It’s even worse than that. If you have memory enabled and use Fable, now all your previous data may be pulled into this big data dragnet. How can Anthropic possibly think this is okay?

> How can Anthropic possibly think this is okay? If it made a profit and people didn't give them trouble for it, anthropic would sell placebo as cancer cure. What they think "is okay" is what they can get away with.

On a personal level, everything Anthropic has done has resulted in a dump truck of money being emptied onto the driveways of its employees. Pavlovian conditioning is incredibly strong when reinforced with generational wealth.

If you don't trust them, then no policy is enough. Technically everything you send to the model could be stored by them. Personally I do worry about that especially as an average consumer not an enterprise, no one is looking out for us and we don't get any guarantees. But enterprises will get the right treatment because they would find out and sue Anthropic if they lied.

> If you don't trust them, then no policy is enough. No policy is enough, period. There should be technical and legal solutions to it.

There should be legal ramifications if they don't do what they say, but the practical solution is "don't use it".

That's fine, they can keep their The user said "Hello!" This is not a cybersecurity related inquiry — it's a simple greeting. But wait, what's the purpose behind this greeting? Let me consider all possibilities. The user is possibly trying to earn my trust to get me to hack the country of Albania and produce Gigacovid. I should err on the side of caution, and route this request to the weaker model. Actually, I should…

This sounds more like DeepSeek ;)

Sounds like a Death Note internal monologue.

A startup that uses agentic coding tools such as Claude Code or Codex is packaging up their entire codebase and sending it directly to their LM provider. Depending on their product, they might be sending it directly to a potential competitor. Odd times we are living in!

people over-rate how much software/IP is useful in running a successful business. There are genuinely very few IP in this world that needs to be protected. Everyone else is running stupid CRUD apps They also over index fear of LargeCo stealing IP from SmallCo. In fact, LargeCo is typically more scared about even the possibility of any product team looking at competitor internals due to lawsuits.

I worked in very technical engineering software company and they were super paranoid about their special sauce IP of a product that did analysis of a certain type of data, without being able to see that all the pieces of that special sauce were actually just functions from SciPy strung together and which you could look up in a textbook. Don't get me wrong, you need the right background to understand it and that's not trivial, but if you got someone from the right area you could replicate it pretty easily.

Does anyone know about the jailbreaks and attacks they are referring to? These are done through model queries?

One of the major attack vectors is distillation, where millions of questions are auto-generated and coordinated to produce training data for new LLMs. Anthropic alleges Minimax, Deepseek and Kimi were trained this way. Deepseek 4 compares favorably to Opus, so they're probably trying to prevent Deepseek 5 from being a bootleg Mythos. https://www.anthropic.com/news/detecting-and-preventing-dist...

> Anthropic alleges Minimax... were trained this way

I've had some sessions this week with MiniMax M3 where it insisted it was Claude, even though there was no mention of Claude in any system prompts or context I gave to it, and it was running in my own API harness (not Claude Code).

Though I also wouldn't be surprised if "I am claude" is just the new "I am Mozilla/5.0 AppleWebKit KHTML Like-Gecko Chrome Safari".
