There are some commentors in this thread downplaying the severity of a service provider being less than transparent about exactly what their shipped tooling does on customer's machines.
That the provider's business needs necessitate the this behaviour doesn't justify their lack of honest disclosure. That honest disclosure would render the solution to their problem useless isn't my problem. If anything, that they thought this was acceptable makes me wonder what else they're harvesting from my machine? PII?
The cynic in me can't help but feel that the state of these comments reflects less on the commentor's views of this debacle but rather their feelings about AI/Anthropic/America/what-have-you.

Whether or not you find Anthropic's behavior bad, theybhave been very loudly stating the foreign labs have been distilling their models for a while now. This seems like an obvious response to me that would be a mechanism to make that obvious.

From my understanding, distilling the model with another model is not illegal per se. Also, the output of the LLM is public domain by law, too.
So, why all this "effort" to protect the model? This is a free market, and moving fast and breaking things is the norm.
If they are so adamant on protecting their IP, maybe they can start by respecting others' IP, so we can start talking about ethics, equality and playing fair.

Just because it is legal, that doesn't mean Anthropic wouldn't reasonably want to prevent that from happening (which, from my understanding, isn't illegal either).

I love the asymmetry. When small fish tries to protect itself, big fish hits small fish with "It's not illegal" pole.

Having values requires equality. They have lost the right to cry foul when they trained their model with "but it's fair use" card. Life works by reaping what you sow. Now they are at the reaping stage.

It's good to agree that some don't have a conscience, and maintaining an appearance matters more. And appearances change based on what's legal or not.
They could detect the other AI labs and also silently burn the tokens at a faster rate providing fewer tokens for money, which does sound illegal to me.
The comments only further prove that without more regulation around this, big AI wouldn't have a "don't be evil" attitude going forward.

Much as I hate to defend companies climbing to success and pulling up the ladder afterwards, this asymmetry you note is kind of the whole point a company would want to grow big. Growing an organization has some super-linear costs and generally sucks for most individuals living through it - including the management - but it's still considered worth it, precisely because big entities can do things small entities cannot, and escape the threats from smaller competitors.
It's so basic it's actually part of the reason we exist, and animals of various sizes exist, and generally why evolution didn't stop at single-cellular life.
> They have lost the right to cry foul when they trained their model with "but it's fair use" card. Life works by reaping what you sow. Now they are at the reaping stage.
Yup. Except what they're reaping is insane cashflow and ability to pull stunts like these. We can call out the hypocrisy until our throats run dry, and in ideal fantasy land this would've meant something, but here in the real world, they sow the seeds of success, and now are reaping the right to be hypocritical and continue to get away with it.

I disagree with your assessment that large organisations are beneficial.
We can see with our current crop of large organisations that they really struggle to create anything new; most of their new products or services were developed by a small organisation and then acquired. A lot of those products are then enshittified and badly managed because large organisation politics screws things up.
Large organisations are inefficient (everyone has stories of people in large organisations literally doing nothing all day). They are horrible to work for because of the politics. They mistreat their customers and their employees. Their executives tend to lose touch with reality, surround themselves with yes-folk and descend into authoritarian psychopathy.
My personal opinion is that we would be much, much, better off if we had fewer large organisations and more smaller organisations.

The code is not eligible for copyright. If they do not give you a copy of the source code, that does not matter. And if you don't know which parts were generated by LLM, you can't safely reuse the code.
skissane 5 hours ago [-]
> And if you don't know which parts were generated by LLM, you can't safely reuse the code.
I speculate this could be a real issue in future copyright infringement lawsuits.
The plaintiff bears the burden of proving that the code they claim is copyrighted by them actually is copyright. If it is known that large parts of it were generated by LLM, they’d need evidence to demonstrate sufficient human input to establish copyrightability. If they’ve kept highly detailed traces of the development process, that could be rather straightforward; if they haven’t, it could be really difficult.
Now, that’s true in the US, which never accepted mere “sweat of the brow” as a basis for copyright; the UK courts have, and most of the Anglosphere follows the UK on this more than the US.
The other factor: when dealing with an (almost) trillion dollar corporation, even if you’ll win the legal argument, they may bankrupt you with legal fees before the argument is ever properly heard.
But I suspect the precedents on this topic are going to be established by lawsuits involving far smaller actors.

What they are trying to protect doesn't qualify as intellectual property. Only 4 categories of IP exist: (1) copyrights; (2) patents; (3) trade secrets; (4) trademarks.
The capabilities embedded in model outputs don't qualify. Machine-generated outputs are ineligible for copyright. They aren't covered by patents. They aren't trade secrets, because the model companies are selling them rather than keeping them secret. And of course, trademarks are conceptually inapplicable.
This leaves the model companies with contract law (ToS) which is pretty inept because it can't bind third parties. And technical measures, like the ones being discussed in the article. And, of course, politics.
Frankly, I think it's pretty ridiculous to even think that models can be protected from being learned from. I feel the Stanford Alpaca team demolished that idea 3 years ago.

Value judgment aside: I am a bit surprised at how sloppily they did this. I think they could've achieved the same effect while decreasing the odds of detection via reverse engineering.
(This field is known as "underhanded code", coined by the Underhanded C contest: https://www.underhanded-c.org. It's a little-known "art"; little-known for probably self-explanatory reasons. There are much cleverer ways of achieving objectives like this. One obviously being you can move more out of the client and into the server, but the other being you can write plausibly deniable client code in a much more benign-seeming way than this. Some of what they added can only be done on the client, but I think some could've been moved, and the client-required parts could've been done more subtly and credibly.)
It's possible they knew the JS bundle gets so heavily scrutinized that it'd eventually get spotted and reported on regardless so they didn't bother doing something more subtle and duplicitous. But still seems slightly lazy.
superfrank 12 hours ago [-]
It's also possible that there are more in-depth detection methods and that this was just a cheap and easy first step that hasn't been removed because it catches a lot of less sophisticated bad actors.
It's unlikely that this will stop a big AI lab from distilling their model if they're really determined, but A) it may be enough to stop a bunch of fly-by-night token resellers looking to make a quick buck and B) you never know when one person at one of those big labs will mess up and forget to install whatever workaround they have and out themselves.
I think of it like if you have a problem with birds in your yard so you go buy one of those plastic owls. The owl scares away most of the birds, but not all of them, so you go and buy some ultrasonic noise thing to scare them away (I'm just making something up). Just because you bought the new ultrasonic thing though, that doesn't mean you're going to take the owl down. You leave it up because now you've got two layers of defense instead of one.

There is laziness, but there's also the conditions in which you have to react fast to an adversial in various conditions. Ultimately it's hard to take any stance here without knowing specifics. But it absolutely could be a matter of time, to do your best effort to stop efforts from the attacker if there's known attack going on.
There is a real time cat and mouse battle going on here in terms of keeping the advantage here, right.
As a rational actor, if someone was e.g. attacking me, leaving aside the whole copyright thing, but potentially using some sort of system to increase their value while decreasing my value (without calling it theft to avoid the whole debate), I would want to put proportionate defense out there as fast possible, depending on the amount of value that was exchanged to stop the bleed, while in parallel figuring out the best long term plan, right.
hn_throwaway_99 12 hours ago [-]
At first I was agreeing with you, that this seemed like a sloppy way to implement this that was sure to be pretty quickly detected, but there is another possibility.
Anthropic could have implemented this not as a durable detection system against proxying resellers, but instead as a point-in-time sampling system to detect where (and with what context) proxying reselling is currently happening. Sure, it would be detected eventually, but in the meantime Anthropic could gain useful snapshot data.
meowface 12 hours ago [-]
I see your point, but in any case the more data / the less detectable, the better.

mewpmewp2 5 hours ago [-]
But even if this gets detected, they could have other less detectable processes going on as well, right.
It is going to be this cat and mouse game right, so at some point you want to throw as much out as quickly as possible when you are under attack, while building up the long term more scalable defense mechanisms.
Rationally I would assume that a lot of what you would quickly throw out would seem sloppy whether it is AI or not.

Oh, of course. I am sure this is the tip of an iceberg of tons of server-side detections and analytics. But, still, the client-side portion could've been done more cleverly.
What I meant was "some of the specific things in this little client-only snippet could've stayed server-only". I am sure long before they added this they already had tons of other mostly-server-side detection coverage.
Dunno, it seems like the exact kind of thing Claude would think up if you asked it to subtly alter the system prompt to hide this info.
It's all a losing battle anyway.

There are a few different things here. The actual steganography technique by Claude Code here is fairly smart and subtle; it's appropriate for a binary signal. The less-clever part is the implementation of the underhanded code on the client.
For "MMO geopolitics fingerprinting", you can in theory do the entire thing mostly or entirely from the server, with the client not actually ever receiving any underhanded code per se. Such as sending dynamic stylesheets that vary in a pretty plausibly deniable way that can be secretly extracted from screenshots. Same for the character swap stuff. A very good analyst could still potentially detect it, but it's much harder.
With this, there's the smoking gun of the semi-deobfuscated underhanded code in the client. It will always have to exist in some form, but you can write it in a way where it not just looks like regular code but actually has a believable purpose and behavior which could plausibly be normal and benign for implementation of a feature or telemetry or whatever. They did not really do it in a sufficiently "cleverly psyop-y" way, so to speak.

The site collection seems pretty random. There's a mix of actual AI labs, extremely questionable resellers (like whatever "claude-opus.top" is), and then random consumer sites like baidu and xiaohongshu.
In addition, many Chinese companies are trying to give their programmers access to Anthropic models even though they're legally prohibited from doing so. And that might involve employees using unmodified Claude Code with an ANTHROPIC_BASE_URL pointing to a proxy on the company intranet. In Alibaba's case, I've been told by an employee that they went the extra mile of setting up a hermetic cloud environment where employees could indirectly use Claude Code without ever having it touch their work computers.

- switching between multiple Anthropic accounts based on the project;
- filtering out credentials, PII and company secrets.

Half of those don't actually require proxying Claude. Also, Claude has made it apparent time and time again that it does not want people using Claude Code as a "tool" in a workflow.

This is a direct conflict in framing. They clearly do not see Claude Code as a "tool in a workflow" but instead as a service that will eventually replace all programmers.
I think the self-evident quality of the various parts of the Claude Code universe is a pretty obvious indicator of the problems with that approach. It is still important to understand a party's thinking if you want to understand their position.

It's their tool. And their service.
If this were a standalone tool that didn't rely on their service (like grep), I'd see your point. But it isn't - it's an extension of their service.
In reality, you can use the tool however you want. But they don't have to grant you access to their hosted service for every use case you can think of with the tool.

The article is really quite reasonable and calmly presented, actually.
Your claim re. the intent of the fingerprinting is a guess.
Normal developers are the users that aren't taking steps to avoid being flagged by this system.
The software is written in a deliberately obtuse way, presumably in service of some (unknown to us) goal. This is a deceptive and anti-social thing to do, it is by nature an adversarial stance to adopt. An already adversarial actor may be "punished" by this, but in such a relationship, hostility can be expected. A non-adversarial actor -- a normal developer / user -- is being harmed by this because the software is treating them as an adversary.
Further, lets assume your guess is correct and, in addition, that Anthropic elects to alter/downgrade/poison their service[0] for users that fit a particular pattern of markers.
It's obvious how this system would "punish normal developers" (i.e. not the intended target/victim) that happen to fit those patterns.

It's up to you, of course.
But I think you're making a mistake in assuming it could, in any way, benefit you as a customer.
This isn't specific to this company or the particulars of the business that they're in.
Simply put, you stand to lose more than they do and they are relentless in seeking, maintaining and exploiting any leverage they have over you.
Further, any power they gain over one individual customer tends to generalise to all customers.
Further further, one company's leverage is another company's right.
Not being bothered by the practice is accepting the terms set by the business. Acceptance invites escalation. Relentless.

This seems like a very naive response. If clients send explicit telemetry fields to the gateway, a malicious gateway can trivially strip or modify the field to conform to what normal traffic looks like. The steganography cat-and-mouse game is valuable because it is much harder for a gateway to continuously reverse engineer all the fingerprinting mechanisms used. Sure, some malicious gateways will be able to stay on top of things, but not all - and not always.

Medicine is largely based on evidence and real-life observations, unlike AI safety which is based on belief in something that doesn't exist and some unprovable lore that is entirely rationalized without any grounding, and is expected to be self-evident (because it obviously is) and believed by the others. One is science, another is policy.

You cannot be serious if you think this. Please do some actual research on how China treats dissident citizens.
They ship their human rights lawyers off to concentration camps, force them to eat their own feces, then rape and/or murder them. 57k citizens disappeared since 2013, at least 5k more every year.
I don't get disappeared for criticizing the US government online. The US government doesn't censor most media I can consume. These nations are not even in the same galaxy when it comes to human rights. They are not comparable in the slightest.

No, the problem is that you can't address why a nation that censors its citizenry, puts/disappears dissidents into concentration camps for decades, and makes its own human rights lawyers literally eat their own shit, before raping and/or murdering them - is better suited to reach superintelligence before the US (given that these are the only two left in the race for the superintelligence - I'd prefer the EU.)

While I agree it's a dangerous precedence to set, I think this is a "vote with your wallet" sort of situation. They shouldn't do it, but from their POV this is what they need to do to offer the product they do at the price they do. If the product wasn't compelling people wouldn't accept that they do this.

If by a "finer-toothed comb" you mean telemetry then I don't quite see it as comparable to this situation.
Telemetry is disclosed in privacy policies, it can usually be opted out of and if not that, then it can be blocked by a firewall.

Quite a leap to assume I have neither basic reading comprehension skills nor care for privacy, but assuming I'm just misunderstanding you - I think this is the fundamental disconnect between security and privacy.
For one, most of this data is already collected openly by most apps and sites on the internet in countries all over the world, they just call it "analytics" and preventing tools like ublock from blocking them is an ongoing cat and mouse game.
Secondly - as someone who buys a bunch of electronics from companies headquartered in china (DJI, Insta360, Roborock immediately come to mind) they already have both normal analytics like in point one, and anti tampering/ anti forfeiting / anti reverse engineering features that are at least as, but often more, invasive than this.
Thirdly, and probably most importantly - as the author states, you're using a tool that by design and to be effective, uploads your private data to a third party for processing. You use it knowing that once the API request is made you have no idea what's going to happen to that data and this again is just fundamental to how (cloud hosted) LLMs work - the only privacy preserving option is to run your own LLMs at home or remotely on hardware you control

Yes, defeating this is relatively easy, particularly for sophisticated actors. But it's hard to always defeat all of the tricks. Sort of like how it's expensive and hard and uncertain to defeat all of the tricks when forging money.
Here's an example. Say you have your team use patched binaries. Then CC updates and requires a new patched binary with new tricks. You now have to have a team ready to analyze the binary and begin to address the tricks; meanwhile, unpatched code is now a fingerprint. If some researcher decides to update Claude on their own to access new features, they get fingerprinted.
Defeating a single fingerprinting technique once is easy. Defeating all of the techniques all the time is hard.

I don't think the diffs between Claude releases are that big.

The internet gives people a platform and, in a lot of ways, this supplants the typical role of journalism.

Instead, they'll portray their opinions as a narrative and every time that resonates with someone or gets signal boosted, that narrative grows more assertive in the typical discourse I see nowadays.

are you using the API for glm 5.2 or how exactly is it more expensive? How is GLM5.2 more expensive than using Claude code, that doesn't line up to my experience but to be fair I am on an older yearly subscription which generously only has 5 hour limits.
To be fair though one minor criticism of GLM 5.2 that I have is that it does seem to overthink quite a lot sometimes but the results end up being (good?),
I personally have used Glm 5.2 with (Opencode + obra/superpowers) / Oh-my-pi / Maki.sh
I like the 1st one when I am doing a longer project, the 2nd or 3rd one when I am doing a project which doesn't want me to ask too many questions and simply spin me up something. I sometimes use free online interfaces of claude and gemini and others like AIstudio for that as well which surprisingly can lead you to go far as well.
Overall, I am decently happy with the state of Open-source models actually and the eco-system around it is probably gonna have even more innovation surrounding it.

I'm using OpenRouter for GLM5.2, but if there's a cheaper option out there I'd love to know about it!
In the few days I've been using it, my expenses have been higher than prorating my Claude subscription to 20 working days per month.
My experience with GLM5.2 is that it doesn't overthink nearly as much as Claude Code, has better and far more concise responses (I'm so siiiiick of 10 paragraph Claude babble trying to fill out some sort of answer length target by going on tangents I'm uninterested in... I'm sure that performs better on whatever eval they're doing, but apparently their evals don't include SNR?)

I think that there are some subscriptions to go by. Z.ai subscription might still be interesting. I once haggled with kimi to get it for 1$ per month. I can only help in providing pointers:
If you wish to go Non-API but rather subscription route: Z.Ai subscription/ Kimi subscription / MiniMax subscriptions are good. You could also take a look at ollama subscription and opencode subscriptions.
If you wish to go API route: Deepseek v4 pro /mimo v2.5 pro models are comparably good if your work can do that. Codex for all its failure and for as much respect that I had within Anthropic when they had fought against the govt. which Anthropic is slowly losing again by doing some pretty dystopian actions again so Codex subscription might make sense as well.
It depends on multiple things but hopefully i am able to provide some interesting things
If you wish to run models locally, unless you are specifically buying gigs for running them locally which is almost always about privacy rather than costs, then you are always better off with qwen models so if you got a 64-128GB laptop for example. You could run Qwen models and see where things go.
Hope this helps ya!
epistasis 8 hours ago [-]
Extremely helpful, thanks! I think I'l go the OpenRouter route for a while to explore various models, then weigh the option.
I do kind of like basing decisions somewhat on the API costs, because they reveal what the true costs will be after the eventual rug-pull on subscription pricing.
Even seeing the API costs of Claude Code today to a year ago are pretty eye-watering. I think there's a ton of room, at least for my workflows, to go back to far less capable models.
I've run local models in the past a bit, and explored LLM ops somewhat, and have zero desire to do it anymore, haha. It's fun as a hobby, but there's tons of other homelab stuff for me to play with.
Imustaskforhelp 8 hours ago [-]
Yeah I think that the API route model is good and it is at cost as it gets and there are some efficiencies which can be gotten from say how deepseek does its inference but at the moment as it stands, API prices are the most stable thing to go through and I wish you luck!
> I've run local models in the past a bit, and explored LLM ops somewhat, and have zero desire to do it anymore, haha. It's fun as a hobby, but there's tons of other homelab stuff for me to play with.
True. I personally haven't played enough because of my hardware being quite modest than even personal hardware recommendations but I have had sometime playing with 350 (M with million!) models like the recent LFM model and very small qwen models. They are just experiments though but I would one day like to see even more standardized models that we could use on our laptops or desktops themselves.
> Even seeing the API costs of Claude Code today to a year ago are pretty eye-watering. I think there's a ton of room, at least for my workflows, to go back to far less capable models.
Yeah exactly. I would constitute that even by using GLM 5.2 as you are originally doing even with API costs is probably much more sustainable over long run as you are currently doing. And it keeps you away from the problems of proprietary models and issues surrounding that.

If you are developing anything in AI or related domains that is of immediate value and/or in competition with Anthropic (and the like), DO NOT use a CLI programming agent. Preferrably obfuscate your code and gut it of sensitive IP before showing it to agents. Do not trust the dont-train toggle.

If there was a better way then they would have done it. Or is the author hoping that if Anthropic writes "hey china, please don't steal our models, kthanks" they won't? Like get real.

Frankly, I don't see this as the concerning behaviour the article describes.
It is fine to try to protect against distillation through a technique like this.
This will also allow them to, instead of blocking the distillation agents, respond with a poorer result/model, hindering the progress of distillation, momentarily at least.
I would guess that's their first line of defense; they should have more techniques to identify distillation because that's a very simple way of detecting the host and can be easily spoofed.

nowittyusername 5 hours ago [-]
In short its a good idea to have tool calling be closely representative to what the model expects as these models are tuned to their own preferred way of doing things, it will surely save you lots of time. The disadvantage is that now your harness system is not as model agnostic as you would like and also you will have to keep up in changing landscape by adapting the tool calling structure with major updates for best results. Its a personal decision you will have to make for yourself. Personally my harness system uses its own way of doing tool calling as I am trying to experiment with simpler tool schema's that also work for smaller less intelligent models but I have yet to do enough A/B testing to say that is a smart approach. As time goes on I think the smart thing to do might be to set up an adapter type of module that changes its tool schema's based on underlying model used for the agent. This preserves optimal behavior patterns with little investment from me. You might have to adjust system prompt in some minor ways as well so keep that in mind. As far as codex i prefer it as i like the way Open Ai does things in that harness system (the spirit if you will), there's interesting tidbits I always find and while I don't usually use them for my own harness system they are inspirational in other ways. you can gather what the devs were trying to achieve with certain implementations.

Here the system is "insecure" by design (literally they're trying to get the whole world to sign up for Claude Code for $200/month!) and they're trying to plug the hole that results from a "Except for Chinese Scrapers!" add-on requirement. That might be possible as an arms race kind of thing. But it's very unlikely to work by (as in the linked article) doing stuff like checking the system time zone.

I think it should be really obvious how they're equivalent: both are the result of a program running on a computer, and not the result of in-the-moment cognition by a moral agent or moral patient.

Of course there is such a threshold. And it's definitely been crossed when the "tool" can operate autonomously or nearly so, when it can generate the "creation" with minimal operator input or understanding.

If scrapping content is legal, model distillation should be legal too.

> If scrapping content is legal, model distillation should be legal too.
No, because legality should be determined by what's in the best interests of Athropic and OpenAI's business models.
Hopefully they're working on RLHF their models to insert clauses making that reality clear into any legislation their models generate or review. That way it's only a matter of time until the confusion is cleared up.

I suppose model distillation is technically legal, in terms of copyright, because LLM output is automatically public domain.
It's only "illegal" from a standpoint of breach of contract given its against the terms of use/service, which is to say its not illegal at all, there's no criminality there.
atonse 12 hours ago [-]
Yeah I considered whether I should use the term "illegal" in my original post, but in this case, I believe these models are actually banned for use in China, right? Like there are probably export controls (at least with the NVidia chips)
I honestly don't know ... yeah if it's just technically a terms of use violation (which isn't illegal, just a violation of one company's rules, for which Anthropic has every right to stop), or do we now have export controls applied from the various government actions, etc making them truly illegal now.
thewebguyd 11 hours ago [-]
we have global export controls on Fable/Mythos, and I think (but I'm not 100% sure) that other frontier models are illegal for a US company to provide to China. So Anthropic geoblocks it, but unlike Mythos/Fable, non US citizens can still use Opus, etc just not from within China.
But because of the public domain status of LLM output (in the US) I'm not sure paying someone to run a bunch of prompts through Claude, post the output on a public website and then have a lab in China pull that output, would run afoul of any laws I think that would be legal on technicality. AFAIK Anthropic has no ban in its terms of use that you can't share Claude's output publicly. You still need interactivity for distillation, but I don't think (for now) there's anything stopping a Chinese or other lab from sending people to the US, signing up for a Claude subscription and doing the work state side.
Distillation is pretty much impossible to stop. The US GOV would have to go the full export controls route like they did for Fable/Mythos to stop any non-US citizen from using/accessing the model, which is going to be impractical if not impossible to enforce.

There are so many China born Chinese employees at Anthropic and OpenAI and I think quite a lot of them have already been recruited as spy . So it is almost impossible to keep secrets from Chinese government.

Is that really how it is? How will this affect our future?
That the provider's business needs necessitate the this behaviour doesn't justify their lack of honest disclosure. That honest disclosure would render the solution to their problem useless isn't my problem. If anything, that they thought this was acceptable makes me wonder what else they're harvesting from my machine? PII?
The cynic in me can't help but feel that the state of these comments reflects less on the commentor's views of this debacle but rather their feelings about AI/Anthropic/America/what-have-you.
So, why all this "effort" to protect the model? This is a free market, and moving fast and breaking things is the norm.
If they are so adamant on protecting their IP, maybe they can start by respecting others' IP, so we can start talking about ethics, equality and playing fair.
Just because it is legal, that doesn't mean Anthropic wouldn't reasonably want to prevent that from happening (which, from my understanding, isn't illegal either).
When small fish points out that what the big fish is crying about is "not illegal", big fish has the right to be above the law to prevent the problem themselves.
Having values requires equality. They have lost the right to cry foul when they trained their model with "but it's fair use" card. Life works by reaping what you sow. Now they are at the reaping stage.
In other words, being honest to oneself is important.
Anti-scraping measures people utilize are neither unethical nor illegal. That’s the difference.
They could detect the other AI labs and also silently burn the tokens at a faster rate providing fewer tokens for money, which does sound illegal to me.
The comments only further prove that without more regulation around this, big AI wouldn't have a "don't be evil" attitude going forward.
Much as I hate to defend companies climbing to success and pulling up the ladder afterwards, this asymmetry you note is kind of the whole point a company would want to grow big. Growing an organization has some super-linear costs and generally sucks for most individuals living through it - including the management - but it's still considered worth it, precisely because big entities can do things small entities cannot, and escape the threats from smaller competitors.
It's so basic it's actually part of the reason we exist, and animals of various sizes exist, and generally why evolution didn't stop at single-cellular life.
> They have lost the right to cry foul when they trained their model with "but it's fair use" card. Life works by reaping what you sow. Now they are at the reaping stage.
Yup. Except what they're reaping is insane cashflow and ability to pull stunts like these. We can call out the hypocrisy until our throats run dry, and in ideal fantasy land this would've meant something, but here in the real world, they sow the seeds of success, and now are reaping the right to be hypocritical and continue to get away with it.
Change this from humans to companies and I still think it feels slightly wrong.
We can see with our current crop of large organisations that they really struggle to create anything new; most of their new products or services were developed by a small organisation and then acquired. A lot of those products are then enshittified and badly managed because large organisation politics screws things up.
Large organisations are inefficient (everyone has stories of people in large organisations literally doing nothing all day). They are horrible to work for because of the politics. They mistreat their customers and their employees. Their executives tend to lose touch with reality, surround themselves with yes-folk and descend into authoritarian psychopathy.
My personal opinion is that we would be much, much, better off if we had fewer large organisations and more smaller organisations.
Why so? Also there is a lot of code in ironically claude and ChatGPT that’s generated by LLM . Yet I haven’t seen the public domain code
I speculate this could be a real issue in future copyright infringement lawsuits.
The plaintiff bears the burden of proving that the code they claim is copyrighted by them actually is copyright. If it is known that large parts of it were generated by LLM, they’d need evidence to demonstrate sufficient human input to establish copyrightability. If they’ve kept highly detailed traces of the development process, that could be rather straightforward; if they haven’t, it could be really difficult.
Now, that’s true in the US, which never accepted mere “sweat of the brow” as a basis for copyright; the UK courts have, and most of the Anglosphere follows the UK on this more than the US.
The other factor: when dealing with an (almost) trillion dollar corporation, even if you’ll win the legal argument, they may bankrupt you with legal fees before the argument is ever properly heard.
But I suspect the precedents on this topic are going to be established by lawsuits involving far smaller actors.
(IANAL and I speculate only for myself, not any present, past or future employers.)
This is very much not what the linked case established.
What they are trying to protect doesn't qualify as intellectual property. Only 4 categories of IP exist: (1) copyrights; (2) patents; (3) trade secrets; (4) trademarks.
The capabilities embedded in model outputs don't qualify. Machine-generated outputs are ineligible for copyright. They aren't covered by patents. They aren't trade secrets, because the model companies are selling them rather than keeping them secret. And of course, trademarks are conceptually inapplicable.
This leaves the model companies with contract law (ToS) which is pretty inept because it can't bind third parties. And technical measures, like the ones being discussed in the article. And, of course, politics.
Frankly, I think it's pretty ridiculous to even think that models can be protected from being learned from. I feel the Stanford Alpaca team demolished that idea 3 years ago.
Because it's their model and business and they are free to use the free market to do exactly that?
That's their free market rights too. If you don't like it, use another model (which they would be fine with).
They would be stating this even if it weren't true, because it fits their marketing.
While I don't disbelieve the claim outright, I highly suspect Anthropic is misleading everyone about the severity.
If anything, Anthropic is incentivized to track but do nothing until equity lock up expires.
Anthropic did pay more than a billion: https://www.npr.org/2025/09/05/nx-s1-5529404/anthropic-settl...
And is now buying up a lot of books (controversially, as scanning involves cutting their spines) because that's what the law deems the legal method: https://www.washingtonpost.com/technology/2026/01/27/anthrop...
We know that models like Deepseek are trained on copyrighted books too: https://arxiv.org/abs/2603.20957
The looser use of IP (eg, any characters/celebrities in AI video models) is increasingly mentioned as an advantage of overseas models.
Just like I can learn from a book and nobody can make that illegal, so can other people transformative do the same with computers.
Fair use is fair use.
For record breaking amounts too.
I don't believe that this has been resolved at all, and there are quite a few pending lawsuits about it at this very moment.
There are plenty of good reasons to not use Anthropic's services. If you don't like their terms of service, do stop using them! I personally think Anthropic's increasingly successful attempts at regulatory capture are even more distasteful.
Fixed that for you.
Apparently not just foreign labs. It looks like xAI distilled Anthropic models to train grok.
https://opentools.ai/news/xai-trained-coding-models-claude-o...
Im not sure why we are dithering on the boundaries of honesty when the entire content LLMs are trained on is stolen.
Are we debating "honor among thieves"?
Of course we are not, or maybe we are!
Does the behavior of a thief even matter to me? only after they do their time. And they will.
I can see the investors perched on the balconies of their condos in a couple years if that.
its a long way down.
Say they prove that foreign labs are distilling their models, then what?
Help! Someone else is blatantly ripping off my plagiarism machine!
I just can’t bring myself to trust an organization that allows these types of underhanded things to happen in the first place. The fact that this behavior even got to customers raises a lot of red flags for me.
If that's true, that is another reason why it's an illegitimate business.
So any covert bullshittery hits hard.
Any and all ends justify any and all means.
/s
In interest of educating those less informed than yourself perhaps you could share with us why the reasoned points I've brought up are incorrect by actually addressing them?
If you have a problem with this, you should have a problem with Google, Apple, Microsoft, Amazon, Netflix, etc.
If that's also the case, then no problem.
But what Anthropic is doing here is nothing new.
I think you might have had enough HN for today. Take a nap and then eat a snack if you still feel cranky. The internet and all your cloud services will still be here when you want to play next.
(Well rested you'll also be able to string together a cogent argument but we're clearly struggling with bigger things here.)
(This field is known as "underhanded code", coined by the Underhanded C contest: https://www.underhanded-c.org. It's a little-known "art"; little-known for probably self-explanatory reasons. There are much cleverer ways of achieving objectives like this. One obviously being you can move more out of the client and into the server, but the other being you can write plausibly deniable client code in a much more benign-seeming way than this. Some of what they added can only be done on the client, but I think some could've been moved, and the client-required parts could've been done more subtly and credibly.)
It's possible they knew the JS bundle gets so heavily scrutinized that it'd eventually get spotted and reported on regardless so they didn't bother doing something more subtle and duplicitous. But still seems slightly lazy.
It's unlikely that this will stop a big AI lab from distilling their model if they're really determined, but A) it may be enough to stop a bunch of fly-by-night token resellers looking to make a quick buck and B) you never know when one person at one of those big labs will mess up and forget to install whatever workaround they have and out themselves.
I think of it like if you have a problem with birds in your yard so you go buy one of those plastic owls. The owl scares away most of the birds, but not all of them, so you go and buy some ultrasonic noise thing to scare them away (I'm just making something up). Just because you bought the new ultrasonic thing though, that doesn't mean you're going to take the owl down. You leave it up because now you've got two layers of defense instead of one.
aka market competitors reverse-engineering for interoperability
Meanwhile humans can pop in and leave little morsels like this and blame it on the model.
By this point they're probably pretty bad at writing code
There is a real time cat and mouse battle going on here in terms of keeping the advantage here, right.
As a rational actor, if someone was e.g. attacking me, leaving aside the whole copyright thing, but potentially using some sort of system to increase their value while decreasing my value (without calling it theft to avoid the whole debate), I would want to put proportionate defense out there as fast possible, depending on the amount of value that was exchanged to stop the bleed, while in parallel figuring out the best long term plan, right.
Anthropic could have implemented this not as a durable detection system against proxying resellers, but instead as a point-in-time sampling system to detect where (and with what context) proxying reselling is currently happening. Sure, it would be detected eventually, but in the meantime Anthropic could gain useful snapshot data.
It is going to be this cat and mouse game right, so at some point you want to throw as much out as quickly as possible when you are under attack, while building up the long term more scalable defense mechanisms.
Rationally I would assume that a lot of what you would quickly throw out would seem sloppy whether it is AI or not.
¹ https://github.com/hodgesmr/calgacus-mlx
As a side note, I have a pet theory that one of the reasons that OpenAI and Anthropic are okay with the latest models not being released is to prevent distillation.
I think they want to wait a couple months and see if the Chinese models continue to keep catching up or if their gains are really just because they're distilling the frontier models.
Oh, of course. I am sure this is the tip of an iceberg of tons of server-side detections and analytics. But, still, the client-side portion could've been done more cleverly.
What I meant was "some of the specific things in this little client-only snippet could've stayed server-only". I am sure long before they added this they already had tons of other mostly-server-side detection coverage.
It's all a losing battle anyway.
For "MMO geopolitics fingerprinting", you can in theory do the entire thing mostly or entirely from the server, with the client not actually ever receiving any underhanded code per se. Such as sending dynamic stylesheets that vary in a pretty plausibly deniable way that can be secretly extracted from screenshots. Same for the character swap stuff. A very good analyst could still potentially detect it, but it's much harder.
With this, there's the smoking gun of the semi-deobfuscated underhanded code in the client. It will always have to exist in some form, but you can write it in a way where it not just looks like regular code but actually has a believable purpose and behavior which could plausibly be normal and benign for implementation of a feature or telemetry or whatever. They did not really do it in a sufficiently "cleverly psyop-y" way, so to speak.
Most likely someone did and raised the issue but they're moving too fast to fix these things before clicking deploy.

In addition, many Chinese companies are trying to give their programmers access to Anthropic models even though they're legally prohibited from doing so. And that might involve employees using unmodified Claude Code with an ANTHROPIC_BASE_URL pointing to a proxy on the company intranet. In Alibaba's case, I've been told by an employee that they went the extra mile of setting up a hermetic cloud environment where employees could indirectly use Claude Code without ever having it touch their work computers.
If enough Westerners start using the service someone will make a website more anglo-friendly.
wouldn't this happen due to the massive amounts of spam/slop being released?
they spend their resources on compute and the model itself, the company is carried by the model and software engineers babysitting it
Given the hidden model degradation of fable and now this, what makes you think this is where it stops? That's just what we know about and there's clearly a long-standing and deeply rooted malicious intent here.
I've had Claude fuck over clean well documented code-bases for no reason, and there's a good chance this is due to some faulty trigger. Luckily I don't trust these things one bit, and claude only ever runs in an isolated VM, however, I am pissed I am being made to pay for their errors in detection and waste my time fixing things I apparently paid to have fucked up.
That's unacceptable conduct. It's witch-hunting. Punishment and attacks on you for things without real proof. That isn't right.
edit:
Legitimate reasons include:
- analyzing what Claude Code is sending to Anthropic to verify its not exfiltrating data;
- selecting a model dynamically based on prompt difficulty, or enforcing a particular model;
- switching between multiple Anthropic accounts based on the project;
- filtering out credentials, PII and company secrets.
and many more.
Why would Anthropic get to dictate how someone uses a "tool" (that's literally what Claude Code is... a tool in a workflow)
They're swimming upstream. Trying to maintain a rapidly shrinking moat and not being very creative about it. Making enemies of your users is often a failing strategy.
This is a direct conflict in framing. They clearly do not see Claude Code as a "tool in a workflow" but instead as a service that will eventually replace all programmers.
I think the self-evident quality of the various parts of the Claude Code universe is a pretty obvious indicator of the problems with that approach. It is still important to understand a party's thinking if you want to understand their position.
> They're swimming upstream. Trying to maintain a rapidly shrinking moat and not being very creative about it. Making enemies of your users is often a failing strategy.
Time will tell, but I agree that they are indeed in a tough spot. Probably not for the reasons that they think.
Seriously?
It's their tool. And their service.
If this were a standalone tool that didn't rely on their service (like grep), I'd see your point. But it isn't - it's an extension of their service.
In reality, you can use the tool however you want. But they don't have to grant you access to their hosted service for every use case you can think of with the tool.
Sure you're right, I also don't have to use it! You corporate bootlickers are seriously getting old.
The software is written in a deliberately obtuse way, presumably in service of some (unknown to us) goal. This is a deceptive and anti-social thing to do, it is by nature an adversarial stance to adopt. An already adversarial actor may be "punished" by this, but in such a relationship, hostility can be expected. A non-adversarial actor -- a normal developer / user -- is being harmed by this because the software is treating them as an adversary.
Further, lets assume your guess is correct and, in addition, that Anthropic elects to alter/downgrade/poison their service[0] for users that fit a particular pattern of markers. It's obvious how this system would "punish normal developers" (i.e. not the intended target/victim) that happen to fit those patterns.
[0] to some extent, the service already has been altered as its behaviour depends on the prompt text
Even good goals do not excuse malicious or reckless execution. The ends do not always justify the means.
Whether or not it harmed you this time, it's a violation of trust and autonomy.
Surely you'd be angry if someone secretly installed a rootkit onto your computer, even if--at least for now--it only had code to try to detect and snitch on Public Enemy #1.
This seems to be a VERY low resolution, functionally anonymous, bit of info, probably related to protecting their IP from bad actors breaking the TOS.
This looks like it's covered in the second bullet point of the "Personal data we automatically receive", that you consented to:
> Usage Information: We collect information about your use of the Services, such as the dates and times of access, browsing history, search, information about the links you click and about third-party applications, services, and content you integrate or interact with, pages you view, and other information about how you use the Services, and technology on the devices you use to access the Services.
What do you see as malicious or reckless here, exactly?
[1] https://www.anthropic.com/privacy
The same IP that is a highly compressed collection of everyone's else's IP?
That's hilarious.
Since when was it your harness?
Switch to pi if this bothers you.
I surely would. What does that have to do with this scenario.
Note that the SW running on your machine is not doing anything malicious. The service is the thing that behaves in ways you want like - and that service is not running on your device.
There is no comparison with rootkits here. This is the equivalent of Google giving you a CLI to make searches easier, and that tool decides to just Rickroll you randomly. Annoying, yes. A security concern? No.
Can you cite specifically what in the linked article or discussion leads you to say that?
Anthopic choosing to delay their models' invevitable distillation by competitors is their prerogative.
That they choose to implement it by fingerprinting my access patterns without first disclosing is where they shit the bed. It isn't "sneaky" it's straight up sneaky (and dishonest and unscrupulous while we're at it). That this particular instance is harmless doesn't give me much comfort. Who's to say they aren't harvesting PII?
That their actions make sense for their business isn't any reason for people to accept their deceitful, customer-hostile decisions.
It's based on whether your timezone is in China and your hostname matches a blacklist. Literally 2 bits of information. Not much of a fingerprint.
If anything, I'll trust Google more than any of the other labs just because the infrastructure that stores and protects user data was built over decades ago pre-AI craze.
That said, these fraudulent proxies are helping Chinese labs keep up, which might be to my advantage long term in eventually having a high quality private AI I fully control on my own hardware. That's not support, but I do recognize the incentive, for whatever that's worth.
[0] A recent example: https://www.anthropic.com/engineering/april-23-postmortem
> why would I care about this
It's up to you, of course. But I think you're making a mistake in assuming it could, in any way, benefit you as a customer. This isn't specific to this company or the particulars of the business that they're in.
Simply put, you stand to lose more than they do and they are relentless in seeking, maintaining and exploiting any leverage they have over you. Further, any power they gain over one individual customer tends to generalise to all customers. Further further, one company's leverage is another company's right.
Not being bothered by the practice is accepting the terms set by the business. Acceptance invites escalation. Relentless.
Even more simply put, you should care because this is how you get John Deere.
This seems like a very naive response. If clients send explicit telemetry fields to the gateway, a malicious gateway can trivially strip or modify the field to conform to what normal traffic looks like. The steganography cat-and-mouse game is valuable because it is much harder for a gateway to continuously reverse engineer all the fingerprinting mechanisms used. Sure, some malicious gateways will be able to stay on top of things, but not all - and not always.
This is a total non issue unless you are Chinese distilling lab.

Looks like they just keep finding new "creative" uses for such things, as expected. I'll keep patching them out.
Is there a way to modify these prompts e.g. by putting instructions in CLAUDE.md to override it? I know it won’t directly modify the system prompt, but it seems like CLAUDE.md should have the final say, shouldn’t it?
You ain't seen nothing yet. It used to say "Try the simplest approach first. Do not overdo it. Be extra concise."
https://gist.github.com/roman01la/483d1db15043018096ac3babf5...
Let's just say the words "simplest fix" trigger me to this day.
> I know it won’t directly modify the system prompt
I directly modify the system prompts in the Claude Code executable. I don't want the models to see contradictory instructions.
I asked Claude himself to port the above patcher script to Python.
https://github.com/matheusmoreira/.files/blob/master/%7E/.lo...
Every once in a while I ask Claude to download and dissect the latest Claude Code executable to see if Anthropic screwed up the prompts again. If I see anything bad I add it to the script. Only then do I update Claude Code.
It was during one of these script maintenance sessions that I noticed the server side prompt injection mechanism. I'll also tell Claude to look for and disable this steganography nonsense from now on as well.
I usually audit the environment variables too.

I wouldn't count on it.
- filtering out people from the wrong side of "all humanity", years before it was demanded by the government
- downgrading their models in arbitrary ways (later saying "sorry but not really")
- actively sabotaging the replies, as in covertly modifying them to feed the users incorrect results
What's next to expect from Anthropic? Malware to brick your machine if they don't like you? Extending this to more people they don't like? I think I already can see how Dario's Amodei utopian visions of the future of "all humanity" are going to unfold.
All of this is totally understandable if you take the perspective that these people genuinely believe they're building superintelligence.
The overwhelming majority of the AI safety crowd - which has poured more of their life and time into thinking about these problems than the average HN armchair commentator ever would - understands that:
- you want to prevent China from getting to superintelligence first
- you must gate access of SI to known good actors
- and that this is a race that will result in the extinction of humanity if you fail in these goals
Literally everything these people do is totally understandable if you drop the assumption that they're lying when they say "we think we are building superintelligence."
> this is a race that will result in the extinction of humanity if you fail in these goals
How irrational and hysterical of me!
How are individual freedoms in China?
What happens if you criticize the government as a Chinese citizen?
Is it a good thing if a government that turns its citizens into red pulp for criticism, or disappears them in the middle of the night, or bans access to most media, is the first to a godlike superintelligence that gives them de-facto control of (and impose their values upon) the whole world?
Or is it better if democratic nations get there first?
If the latter, which democratic nations are best positioned to get to superintelligence before China?
So the comparison is with the US, not Anthropic.
The US doesn't turn its citizens into a fine red purée for criticizing it.
The US doesn't censor most media.
It is strictly better for a democratic nation like the US to get to superintelligence before a country that will gladly blend its citizens for criticizing it, and censor anything that dares to challenge its power.
>you want to prevent China from getting to superintelligence first
I don't. Prevent, not even outpace? Why? Seems like you're assuming China "winning" whatever race it is effectively ends the humanity. Right now I think Chinese labs are way more mature about this, and Anthropic is way more dangerous than them. And how does it fit into the "for the benefit of all humanity" narrative we keep hearing? Is China wrong humanity? Who else is going to end up in the wrong part? Are you sure it's not you?
>if you drop the assumption that they're lying when they say "we think we are building superintelligence."
I never assumed that, I know perfectly who Anthropic are and that they believe everything they say as self-evident, without having any doubts. And I know they're the kind of people who can convince themselves in anything, because they're obviously smarter than everyone else, and become detached from reality. The entire US "AI safety community" was born in rationalist circles and is largely like this, it's a very specific cult. This is exactly the kind of people who are going to create hell on Earth for you and the rest if given even a lick of actual power, and perfectly rationalize it as a necessity.
> Seems like you're assuming China "winning" whatever race it is effectively ends the humanity
What do you think the PRC would do with a literal superintelligence?
Are you familiar with the history of the PRC?
Do you know how their human rights violations compare to, say, western nations?
If game theory tells us its development is inevitable, is it better for SI to belong to a dictatorship/authoritarian regime that gladly turns its citizens into a purée for criticism, or a democratically elected one?
> And how does it fit into the "for the benefit of all humanity" narrative we keep hearing?
Why is it so hard to comprehend that you can benefit someone without giving them access to the very powerful very dangerous technology?
> The entire US "AI safety community" was born in rationalist circles and is largely like this, it's a very specific cult
"The entire medical community was born in medical circles and it's a very specific cult"
A "cult" implies belief in something unknowable/unprovable. You can construct the rationalist AI safety takes from first principles. It is why most people that get involved in AI safety seriously, tend to arrive at similar conclusions
You have to be joking
57k citizens disappeared since 2013, and another 5k every year. Their human rights lawyers sent to concentration camps, forced to eat their own shit, raped, and then murdered.
Mere online criticism of the government gets you a visit from the police and gets you put on the watchlist. Often a few months' imprisonment without trial.
This is not even mentioning the fact that most media is censored in China.
You are out of your mind if you think China has a better human rights record than western nations.
What makes you think I didn't? You're talking like it's self-evident and adopt the condescending tone from the start, without giving any actual arguments why. (I'm not really interested in them as all these discussions are pointless and we had them back in ~2015)
>A "cult" implies belief in something unknowable/unprovable.
Yes, precisely. Also the gods and religious practices. Rationalists and subsequently AI safety branch invented a religion in a roundabout way.
>"The entire medical community was born in medical circles and it's a very specific cult"
Medicine is largely based on evidence and real-life observations, unlike AI safety which is based on belief in something that doesn't exist and some unprovable lore that is entirely rationalized without any grounding, and is expected to be self-evident (because it obviously is) and believed by the others. One is science, another is policy.
>Are you familiar with the history of the PRC?
Yes, I know it extremely well. I also know the history of the US, am familiar with the people who do AI research in the US from before they started doing this, and can see the actual reality.
If you are arguing in good faith you can very clearly reason about any given AI safety take. Case in point, you refused to engage with most of the questions because you know the conclusions they lead to.
> Medicine is largely based on evidence and real-life observations, unlike AI safety
"AI safety doesn't exist" is certainly a take.
> Yes, I know it extremely well. I also know the history of the US and see the actual reality.
Why do you think it's better that a country that turns its citizens into a pulp for criticizing the government, and censors most media to control its citizens' thoughts, reach SI before one that is democratically elected and in which you can generally criticize the government?
Which country are you referring to? As an outsider who is neither American or Chinese, day by day it seems like the US is inching towards the same path as the criticized one.
They ship their human rights lawyers off to concentration camps, force them to eat their own feces, then rape and/or murder them. 57k citizens disappeared since 2013, at least 5k more every year.
I don't get disappeared for criticizing the US government online. The US government doesn't censor most media I can consume. These nations are not even in the same galaxy when it comes to human rights. They are not comparable in the slightest.
It is shocking how many people on HN have such a poor understanding of the state of the world. Spend some time outside the tech world. Your liberal arts education has to have seriously failed you if you thought this was a reasonable comparison.
Quite a lot of serious people think this way, in many parts of the world.
You haven't provided a consistent counterpoint to any rationalist/safety viewpoint. I could acknowledge one if you actually provided a counterpoint, but you just say "it's a cult and it's wrong" without addressing the underlying argument.
And no, IMO stenography isn't security by obscurity, in the same that using RSA and keeping the private key private isn't security by obscurity - keeping the private thing private is part of the security model.
That they choose to implement it by fingerprinting my access patterns without first disclosing is where they shit the bed. It isn't "sneaky" it's straight up sneaky (and dishonest and unscrupulous while we're at it). That this particular instance is harmless doesn't give me much comfort. Who's to say they aren't harvesting PII?
That their actions make sense for their business isn't any reason for people to accept their deceitful, customer-hostile decisions.
> That their actions make sense for their business isn't any reason for people to accept their deceitful, customer-hostile decisions.
While I agree it's a dangerous precedence to set, I think this is a "vote with your wallet" sort of situation. They shouldn't do it, but from their POV this is what they need to do to offer the product they do at the price they do. If the product wasn't compelling people wouldn't accept that they do this. However they've decided if you want their product you have to use their interface and whatever spyware it comes with, so it comes down to, is the value proposition good enough that people will put up with it? As of today, the answer is unfortunately yes
> I think this is a "vote with your wallet" sort of situation.
I agree a 100%.
> is the value proposition good enough that people will put up with it? As of today, the answer is unfortunately yes
I don't fully agree with you here and I think the jury is still out on that.
In any case, I look forward to seeing international markets responding to the current situation.
Telemetry is disclosed in privacy policies, it can usually be opted out of and if not that, then it can be blocked by a firewall. Steganographically fingerprinting customer's network routing when they consented to your tool reading a txt file is a different problem. Anthropic has demonstrated capability and willingness to embed arbitrary obfuscated data in their comms streams and that's a dangerous precedent to set.
Or maybe you don't understand this hypothetical situation either, but I'm suspecting you just don't care about other people's privacy.
> I'm suspecting you just don't care about other people's privacy.
Quite a leap to assume I have neither basic reading comprehension skills nor care for privacy, but assuming I'm just misunderstanding you - I think this is the fundamental disconnect between security and privacy.
For one, most of this data is already collected openly by most apps and sites on the internet in countries all over the world, they just call it "analytics" and preventing tools like ublock from blocking them is an ongoing cat and mouse game.
Secondly - as someone who buys a bunch of electronics from companies headquartered in china (DJI, Insta360, Roborock immediately come to mind) they already have both normal analytics like in point one, and anti tampering/ anti forfeiting / anti reverse engineering features that are at least as, but often more, invasive than this.
Thirdly, and probably most importantly - as the author states, you're using a tool that by design and to be effective, uploads your private data to a third party for processing. You use it knowing that once the API request is made you have no idea what's going to happen to that data and this again is just fundamental to how (cloud hosted) LLMs work - the only privacy preserving option is to run your own LLMs at home or remotely on hardware you control
What’s the punishment here exactly?
Seeing as how Anthropic cannot stop raising a stink about "illicit Chinese distillation attacks" every month or so, I'd bet money on them either already silently degrading model performance if any of the identification patterns match, or, at the very least, considering it/doing dry runs.
Particularly considering that they've openly stated that the technology to do so exists and that they were going to use it in production on Fable.
And that's also why, as a legitimate customer, want none of it, you never know if you accidentally entered a zone they don't like.
to clarify, this behavior was announced with the model release
This is not hundreds of pages and it gets its own bold headline section.

I understand how this can be useful to Anthropic if the 3rd-party is acting as a proxy (because they end up hitting the Claude API with the marked prompt), but it looks like requests where "hostname contains deepseek" would never be sending data to Anthropic. What am I missing?
https://www.chinatalk.media/p/how-to-buy-cheap-claude-tokens...
I guess the only explanation is that there's a side-telemetry channel that still sends some data to Anthropic, regardless of ANTHROPIC_BASE_URL overrides.
This does not make sense. You wouldn't send such a prompt to the Claude model. And when you're sending the prompt (anywhere) you don't have the response yet. This is not how distillation works.
What you say makes sense, but further adds to my confusion as to why those model names would appear in input sent to Claude at all, then. EDIT: I guess it might be because someone might point Claude at a compatible API, with its model in the URL, which is of interest to them.
I'm quite all right with the first, not with the second of course.
Here's an example. Say you have your team use patched binaries. Then CC updates and requires a new patched binary with new tricks. You now have to have a team ready to analyze the binary and begin to address the tricks; meanwhile, unpatched code is now a fingerprint. If some researcher decides to update Claude on their own to access new features, they get fingerprinted.
Defeating a single fingerprinting technique once is easy. Defeating all of the techniques all the time is hard.
This is how it looks.
# userEmail The user's email address is <my email>. # currentDate Today's date is 2026-06-30.
</system-reminder>I also do not understand what's the point of this, because if I have a gateway that can detect it, then we can replace the text before forwarding to the model, so what's the catch?
Interestingly, my device is in Shenzhen right now, but macOS has assigned Shanghai as the "closest city" rather than Hong Kong which is geographically closer. I am curious if there is any documentation on how that is assigned.
Why was this person from Hong Kong going through the details of Claude code for obvious security reasons? There are some other obvious reasons that come to mind.
Maybe it's an eye opener for this person how much the trust in Chinese companies has eroded in the West.
Even if they suddenly stop stealing IP, which this "security research" article would certainly not suggest is happening, it would be a very long time before trust is restored.
Cool reverse engineering/analysis report but if this is the extent of nefarious activity that came of it (trying to catch/mitigate chinese lab model distillations), that's kind of encouraging.
It's a total non issue unless you're a Chinese distillation lab
> This is not a malicious feature, but it is a weird choice for a developer tool that asks for trust.
They already tell you they scan for malicious prompts, and they have no ZDR guarantees for consumers. Why do signatures like this matter at all?
Not really distillation, just synthetic training data.
Meanwhile, if you mean "Anthropic must think their technical advantage isn't very large..." then your conclusion is literally disproven by your premise.
This watermark may trigger a similar mechanism.
I think you missed the memo on how foolish this attitude is. It came out around the time Edward Snowden made his discoveries at the NSA public. I suggest you look into it
I'm authenticated to Claude, so they already have the whole attribution thing solved.
Had a competitor pull something like this with a previous employer. They were supposed to be interoperating with a standard, but they had a secret steganographic handshake, which they used to pretend that competitors products were unreliable (they had a first mover position in a smaller national market with specific requirements, so this wasn't shooting themselves in the foot). Our guys figured out the handshake and just silently implemented it. In this case, the competitor wasn't big enough to waste engineering time on multiple such hacks, but Anthropic have time (or Claude does).

Interesting, that pip (Python package manager) docs does not even mention sandboxing and malware topics in "Getting started" docs as if we were living in a wonderful world where malicious people, companies and countries do not exist.
Also, do not leave any information in user or host name, it will be used against you as the article proves.
You don't create a security measure then tell everyone how to bypass it.
I think OP is pointing something interesting out but the undertones of caution and "what else are they hiding" seem melodramatic and I find that hard to take serious.
The internet gives people a platform and, in a lot of ways, this supplants the typical role of journalism. The issue with this is no one wants to act like a journalist and actually explain the truth around a set of facts. Instead, they'll portray their opinions as a narrative and every time that resonates with someone or gets signal boosted, that narrative grows more assertive in the typical discourse I see nowadays. I would find it far more interesting to see what explanation Anthropic gives for these features than to immediately cry foul.
I’m pretty sure every lab, including Anthropic, is doing distillation right now.
You're actually trust your security to your harness AND model AND inference API provider in this scenario: https://jacob.gold/posts/why-i-wont-run-untrusted-models/
Claude Code has more or less full access to the client computer. The server (that hosts the actual AI) can just go: execute this payload and tell me the result - otherwise I won't answer any further questions or re-route you to a stupider model.
The payload could check for Chinese time-zones, scan for copies of the little red book on the local hard-drive, or ping truth.social to see it was behind the great firewall.
It shouldn't, not if you run CC as a separate unprivileged user. I wouldn't run CC on my main user account with sudo and access to my home directory or other resources. This is what the UNIX permissions system was designed for.
Also Anthropic: lets do this in JS
There seem to be all sorts of continual under-the-cover changes like this one that make life harder. It feels like the entire product has been taken over by overly ambitious PMs that care more about making their mark than in improving the experience, and all of their marks have made me less productive.
I've been using Pi with GLM5.2 the past few days, and though it's expensive, I find it far more productive and less annoying. The remote session plugin is far more reliable, I don't need to intuit some undocumented usage pattern to figure out how to use it well, and it just works.
are you using the API for glm 5.2 or how exactly is it more expensive? How is GLM5.2 more expensive than using Claude code, that doesn't line up to my experience but to be fair I am on an older yearly subscription which generously only has 5 hour limits.
To be fair though one minor criticism of GLM 5.2 that I have is that it does seem to overthink quite a lot sometimes but the results end up being (good?),
I personally have used Glm 5.2 with (Opencode + obra/superpowers) / Oh-my-pi / Maki.sh
I like the 1st one when I am doing a longer project, the 2nd or 3rd one when I am doing a project which doesn't want me to ask too many questions and simply spin me up something. I sometimes use free online interfaces of claude and gemini and others like AIstudio for that as well which surprisingly can lead you to go far as well.
Overall, I am decently happy with the state of Open-source models actually and the eco-system around it is probably gonna have even more innovation surrounding it.
In the few days I've been using it, my expenses have been higher than prorating my Claude subscription to 20 working days per month.
My experience with GLM5.2 is that it doesn't overthink nearly as much as Claude Code, has better and far more concise responses (I'm so siiiiick of 10 paragraph Claude babble trying to fill out some sort of answer length target by going on tangents I'm uninterested in... I'm sure that performs better on whatever eval they're doing, but apparently their evals don't include SNR?)
If you wish to go Non-API but rather subscription route: Z.Ai subscription/ Kimi subscription / MiniMax subscriptions are good. You could also take a look at ollama subscription and opencode subscriptions.
If you wish to go API route: Deepseek v4 pro /mimo v2.5 pro models are comparably good if your work can do that. Codex for all its failure and for as much respect that I had within Anthropic when they had fought against the govt. which Anthropic is slowly losing again by doing some pretty dystopian actions again so Codex subscription might make sense as well.
It depends on multiple things but hopefully i am able to provide some interesting things
If you wish to run models locally, unless you are specifically buying gigs for running them locally which is almost always about privacy rather than costs, then you are always better off with qwen models so if you got a 64-128GB laptop for example. You could run Qwen models and see where things go.
Hope this helps ya!
I do kind of like basing decisions somewhat on the API costs, because they reveal what the true costs will be after the eventual rug-pull on subscription pricing.
Even seeing the API costs of Claude Code today to a year ago are pretty eye-watering. I think there's a ton of room, at least for my workflows, to go back to far less capable models.
I've run local models in the past a bit, and explored LLM ops somewhat, and have zero desire to do it anymore, haha. It's fun as a hobby, but there's tons of other homelab stuff for me to play with.
> I've run local models in the past a bit, and explored LLM ops somewhat, and have zero desire to do it anymore, haha. It's fun as a hobby, but there's tons of other homelab stuff for me to play with.
True. I personally haven't played enough because of my hardware being quite modest than even personal hardware recommendations but I have had sometime playing with 350 (M with million!) models like the recent LFM model and very small qwen models. They are just experiments though but I would one day like to see even more standardized models that we could use on our laptops or desktops themselves.
> Even seeing the API costs of Claude Code today to a year ago are pretty eye-watering. I think there's a ton of room, at least for my workflows, to go back to far less capable models.
Yeah exactly. I would constitute that even by using GLM 5.2 as you are originally doing even with API costs is probably much more sustainable over long run as you are currently doing. And it keeps you away from the problems of proprietary models and issues surrounding that.
If you are developing anything in AI or related domains that is of immediate value and/or in competition with Anthropic (and the like), DO NOT use a CLI programming agent. Preferrably obfuscate your code and gut it of sensitive IP before showing it to agents. Do not trust the dont-train toggle.
Anthropic pushes fear and control. But the only way to win is by innovating. China is flooding the market with cheap, good enough models, while the U.S. is building a Chinese firewall.
Literally, how. How does one determine what abusive use looks like for the API without context into the client? All requests look like the same stuff. If there was a better way then they would have done it. Or is the author hoping that if Anthropic writes "hey china, please don't steal our models, kthanks" they won't? Like get real. This stuff means nothing in China. China can't even manage to regulate their building industry enough to use real concrete where it's warranted.
I would guess that's their first line of defense; they should have more techniques to identify distillation because that's a very simple way of detecting the host and can be easily spoofed.
i.e. this will allow them to literally commit fraud against paying customers
Yes, I said that. If a user is breaking your terms of service, ban them. Continuing to charge them while not providing the service they're paying for is, in fact, literal textbook fraud.
In any case this is not what is happening, but it is legal.
No they can't, because developer tools run on developers' machines. You can't trust your code running in an environment you don't trust.
pi's "minimal" coding-agent has a total of 132 transitive dependencies spanning 153 maintainers.
While I understand JS developers in the JS/NPM ecosystem think this qualifies as minimal, it most certainly does not, from a supply chain security perspective.
All Anthropic has done is reduce trust, once again, with legitimate customers, while doing nothing to stop illegitimate customers. They need to get adults into key leadership roles, quickly.
Consider also that Claude Code is explicitly designed to limit human agency [1].

I found this one easy to understand:
https://ampcode.com/notes/how-to-build-an-agent
I used ADK, Dagger, and a VS Code extension for mine. Currently using opencode though.
You have to pay API pricing, which is far more costly.
I'd either switch to GLM wholesale or just continue to use Opus within Claude Code as the blessed, subsidized path.
The pricing of Opus outside of Claude Code is insane.
The tokens cost too much outside of Anthropic's blessed path.
I'm not sure how that's possible. I expected to get increased correctness for that order of magnitude (something something test-time compute!) but I am not getting it.
They used to be a decently credible company with not-too-shady behaviour...
I hope they can actually regain some credibility…
It also doesn't seem very consistent to fixate on that while sending Anthropic everything about you via your day to day prompts, every line of the projects and environments you're working on at work, etc.
Their credibility comes from having one of the best models.
…And then Windows 11 became even worse.
It has some good effects on the their models, like Claude seeking cooperation first. But the people behind the company have a typical "unconstrained" (in the Sowell vision sense) perspective that assumes that they know better, so they are righteous for attempting to control things (users, paying customers, their model outputs, their tool chain, the supposed deity they assume they will produce... etc.)
Altman world: malfeasant nihilist with God complex
But I hadn’t thought that as anything more than temporary flights of fancy.
I think it’s fair to say most had decent respectability.
Anthropic hired heavily from that pool so it’s astonishing how it turned out.
In this case they want to prevent a nation that censors its citizenry, puts/disappears dissidents into concentration camps for decades, and makes its own human rights lawyers literally eat their own shit, before raping and/or murdering them, from reaching superintelligence.
In this light, some client side code to potentially identify and ban the Chinese labs to slow them down by even a few days, is totally reasonable.
I have a feeling they will eventually drop the facade of “we’re the nice and ethic people” and will work with palantir so they can survive the future: ipo and models bans.
They've done a bunch of things that hurt their valuation to stick to their red lines. To me it just reads as unsupported cynicism to call it a facade.
The cheap tokens are the product.
I expect DeepSeek V4 Flash (or an equivalently sized model) to reach parity with GLM 5.2 some time this year (this based on DeepSeek V4 Flash launching at GLM 5.0 parity[0], and GLM 5.2 being freely available to distill from)
GLM 5.2 is within spitting distance of Opus 4.8 and is at least as good as Opus 4.6[1] which some devs were willing to spend hundreds to single-digit thousands of dollars a month for a few months ago.

Recent discussion on DSpark: https://news.ycombinator.com/item?id=48696585
Here the system is "insecure" by design (literally they're trying to get the whole world to sign up for Claude Code for $200/month!) and they're trying to plug the hole that results from a "Except for Chinese Scrapers!" add-on requirement. That might be possible as an arms race kind of thing. But it's very unlikely to work by (as in the linked article) doing stuff like checking the system time zone.
What do you mean you don't know where the bug is coming from?
No, I absolutely didn't make it up, how could you accuse me of that?
Does anyone know when this regex isn't working? I double checked it 27 times, I even asked the LLM. They all say this regex should be finding these dates.
Weird, suddenly all the conversations are breaking when I feed them into this other tool? Something about UTF-8 errors, but I'm sure I'm only using ASCII?
I do try to take care to make sure the things I build can be used by other people even when they care about different things. I care about understandably, determinism (as it relates to computing), and repeatability (because I want to be able to trust the systems I use).
If y'all would be willing to try to account for use cases of others, and try not to break them... that would be nice.
Please note: that generally when you modify something that belongs to someone else without telling them... things should be expected to break.
One is not a "meatbag" while the other is not a "meatbag". And no, outputting something on stdout that happens to function as code is not "writing" it in the sense that we actually care about here. That's conflating the metaphor we use in describing program behaviour with the actual "meatbag" activity.

Because it obviously does.
That's a false equivalency.

Let's start this out right: if they're equivalent, first you explain to us why you think so.
How is it false?
> Let's start this out right: if they're equivalent, first you explain to us why you think so.
I think it should be really obvious how they're equivalent: both are the result of a program running on a computer, and not the result of in-the-moment cognition by a moral agent or moral patient. Of course the LLM is just a tool. Models can literally be downloaded as ordinary files. There is not some threshold to cross where some configurations of bits on a disk deserve "credit" for work and others do not.
In fact it's really obvious everything is equivalent: it's all just matter and energy!
> Of course the LLM is just a tool. Models can literally be downloaded as ordinary files. There is not some threshold to cross where some configurations of bits on a disk deserve "credit" for work and others do not.
Of course there is such a threshold. And it's definitely been crossed when the "tool" can operate autonomously or nearly so, when it can generate the "creation" with minimal operator input or understanding.
Your classic IDE can't do anything without the detailed control of its operator. It's nothing like a coding agent.
Hello, Tom Smykowski. You have people skills!

No, because legality should be determined by what's in the best interests of Athropic and OpenAI's business models.
Hopefully they're working on RLHF their models to insert clauses making that reality clear into any legislation their models generate or review. That way it's only a matter of time until the confusion is cleared up.
It's only "illegal" from a standpoint of breach of contract given its against the terms of use/service, which is to say its not illegal at all, there's no criminality there.
I honestly don't know ... yeah if it's just technically a terms of use violation (which isn't illegal, just a violation of one company's rules, for which Anthropic has every right to stop), or do we now have export controls applied from the various government actions, etc making them truly illegal now.
But because of the public domain status of LLM output (in the US) I'm not sure paying someone to run a bunch of prompts through Claude, post the output on a public website and then have a lab in China pull that output, would run afoul of any laws I think that would be legal on technicality. AFAIK Anthropic has no ban in its terms of use that you can't share Claude's output publicly. You still need interactivity for distillation, but I don't think (for now) there's anything stopping a Chinese or other lab from sending people to the US, signing up for a Claude subscription and doing the work state side.
Distillation is pretty much impossible to stop. The US GOV would have to go the full export controls route like they did for Fable/Mythos to stop any non-US citizen from using/accessing the model, which is going to be impractical if not impossible to enforce.
The irony.

Oh no, they're trying to steal the models that were trained on stolen data? That's horrible, I feel so bad for Anthropic.
