> Opus 5.5 is the first Opus model to launch with a similar class of safeguards to Fable 5.1 on cybersecurity, biology, and distillation, all of which fall back to another model transparently.

This is where Chinese models are going to eat Anthropic's lunch.

They have for sure improved the safeguard classifier. I have a coding agent guard OSS tool [1] and I use Claude to build it. When Fable first came out, I was simply unable to do any work with it. Nowadays their classifier triggers but very rarely.

However, the moment that someone uses a Chinese model without guardrails to commit an AI-powered 9/11, DC will rush to ban Chinese models. (A happy side effect will be to protect American AI profits.)

So the lack of guardrails is a very risky proposition...

In those specific domains, sure. What percentage of paying users would you say that is?

We went from open source Chinese models eating _all_ of frontier labs lunch, to them eating some small extremely niche market of frontier labs.

I don't think this will happen, just as Chinese models did not eat Anthropic/OpenAI's lunch on top tier intelligence. The market is way too niche, and the parties already interested in the capabilities behind safeguards are likely already partnered with Anthropic to get around those with Mythos-class models (see project glasswing for cybersec).

So it will not usable to do anything with hardening Your own site.... I'm so tired of this. I just want adjust cookie behavior of own site...

You have to understand you are in a bubble. 99.99% of people will never be effected by it nor care about it. It will have nothing to do with Anthropic succeeding or failing.

I don't even want to know what safeguards regarding biology exist.
