The post is light on details, and I agree with the sentiment that it reads like marketing. That said, Opus 4.6 is actually a legitimate step up in capability for security research, and the red team at Anthropic – who wrote this post – are sincere in their efforts to demonstrate frontier risks.

Opus 4.6 is a very eager model that doesn't give up easily. Yesterday, Opus 4.6 took the initiative to aggressively fuzz a public API of a frontier lab I was investigating, and it found a real vulnerability after 100+ uninterrupted tool calls. That would have required lots of of prodding with previous models.

If you want to experience this directly, I'd recommend recording network traffic while using a web app, and then pointing Claude Code at the results (in Chrome, this is Dev Tools > Network > Export HAR). It makes for hours of fun, but it's also a bit scary.

Glad to see that they brought in humans to validate and patch vulnerabilities. Although, I really wish they linked to the actual patches. Here's what I could find:

https://cgit.ghostscript.com/cgi-bin/cgit.cgi/ghostpdl.git/c...

https://github.com/OpenSC/OpenSC/pull/3554

https://github.com/dloebl/cgif/pull/84

Grepping for strcat() is at the "forefront of cybersecurity"? The other one that applied a GitHub comment to a different location does not look too difficult either.

Everything that comes out of Anthropic is just noise but their marketing team is unparalleled.

Yawn.

"Evaluating and mitigating the growing risk of LLM-developed 0-days" would be much more interesting and useful. Try harder, guys.

Is there a polymarket on the first billion dollar AI company to 0$ by their own insecure Model deployment?

This reads like an advertisement for Anthropic, not a technical article.
