Anthropic's RSPv3 didn't consider cybersecurity a major threat area. I think this vindicates my reaction of: This is not about rules or promises anymore, it is all about whether you trust Anthropic to make good decisions based on the actual situation that arises.

Anthropic announces Project Glasswing, a cybersecurity initiative that will use its Claude Mythos Preview model to help find and fix software vulnerabilities

Today we're announcing Project Glasswing1, a new initiative that brings together Amazon Web Services, Anthropic, Apple, Broadcom …

Imagine being Dario, and being told DoW is worried you might sabotage the weights of Claude Gov in physically impossible ways, while you know you have zero-days on every operating system and browser in the world.

They accidentally trained against the CoT for Opus 4.6, Sonnet 4.6 and Mythos for 8% of RL. So let me be clear, at a minimum: ANY AND ALL REASSURING EVIDENCE FROM THEIR CoTs IS WORTHLESS. They are hopelessly corrupted. Good day, sir.

Anthropic says it will make Claude Mythos Preview available to 40+ organizations that maintain critical software and doesn't plan to make it generally available

Anthropic on Tuesday released a preview of its new frontier model, Mythos, which it says will be used by a small coterie of partner organizations for cybersecurity work.

This is very bad news. Anthropic (presumably) not noticing the severity of the issue is worse news. If Anthropic pretends this is not as bad as it is even after this is pointed out, it is far worse news than that.
