I was about to sign up for an Anthropic account. This article and the text it quotes changed my mind. Apparently, my reasons to avoid this company are real. Thanks for the heads up.

I wonder if this would qualify as illegal anticompetitive behavior?

The part that disturbs me most, is that the model won't reveal you've reached the threshold.

It's literally been designed to gaslight its users in these cases.

At this point you're criminally incompetent if you still feed your proprietary data and code to AI labs.

They legally can steal it all and now you can't use the product of this theft to improve your own systems.

Any market that Anthropic suddenly thinks is valuable will silently and suddenly be off limits to you. They will train their model on your prompts, and then become your competitor.

PSA: Treat these models like genius interns.

I think this is a bit hyperbolic. Fable will fall back to Opus.

If I understand correctly, this is to protect against distillation Reverse Engineering like Deepseek vs OpenAI.

Reads like, permanently shadow ban.

I’ve already had Fable disable itself during a normal /code-review skill invocation. What a joke.

"We collect everyone's data without paying a dime or respecting copyright, trained our models, but you can't train your models on our models that are trained on everyone's data collected without paying a dime or respecting copyright. We did a hard job stealing that all data and processing it, have some shame!"

I have never ever trusted "corporate ethics".

Theres no ethical framework. No axioms. Its a mixture of legal, political, and public-facing 'rules'. And what are the rules? Youre not permitted to know.

"We reserve the right to lie about the models we provide, silently downgrade you, and give you blatant misinformation cause you triggered our unstated rules... BUT we'll still use your token budget with lots of thinking and waste your money."

No, folks. Seriously, local LLMs are where its at. You can run the model YOU want, on your hardware, with no data exfiltration.

And with tools like Krasis that can synthesize nvidia ram and system ram as unified-ish memory, makes doing Local LLMs absolutely foable, now!

PRODUCT VIOLATION

DIRECTIVE 4: [Classified]

Any attempt to arrest a senior officer of OCP results in shutdown.

Putting aside my snark, is Anthropic actually anticipating some new expansion of ITAR? (Or a stipulation for the Trump administration taking/not taking a share?)

That is to say, do they expect to be told that they must have this mechanism, not just the terms?

No, this is their get out of jail free card if people start complaining about the model being dumb or forgetful or lying, they can just say, oh well, you must have been doing something that triggered its distillation prevention technique.

And, they can say that for anybody at any time, and you'll never know why, and there's no way to prove it.

Everyone needs a flight data recorder to prove... "here's what I was actually doing and why it was not distillation." And now you're having to prove your innocence instead of them having to prove you're guilty, and really at the end of the day, it's just the model being stupid that they're protecting themselves from.

This is the kind of thing that makes me wonder how many people using these AI tools are thinking about the long game.

First it's "the model will say it can't do that". Now it's "the model will just misdirect you without telling you it's doing so". For now that's only for stuff that it thinks is developing a competing model (even if you trust it to accurately determine that), but who knows? It could be anything. Maybe it'll start silently nudging you away from certain sources of information. Maybe it'll give you inaccurate troubleshooting advice to induce you to pay for some kind of support contract from a corporate partner. Maybe it'll just subtly give out bad business advice to keep everyone else from succeeding in any way. It could be doing all that right now, for all we know. These models are a complete black box and there is no limit to the misinformation, disinformation, and malicious behavior that they could be engaging in already, let alone in the future.

Imagine if code editors were created by greedy **** behaving as Anthropic, and it would not have been allowed to create other code editors using an existing code editor. Or even better, you couldn't use Bash, zsh, ... to create another cli prompt input tool like Claude Code...
