It would be amazing (wrong word? Needed? Important?) to see @simonw as one of the trusted testers of Mythos. It makes all the sense in the world to invite the person behind the idea of the Lethal Trifecta. I hope someone at @Anthropic invites him into the project. There should be

Congrats to Anthropic on the strong scores across the board, and congrats on being the first big lab to report SWE-bench Multimodal scores. We will be launching the Multimodal leaderboard & open source test set in the coming weeks.

This is beyond insanity. That jump is nuts. Opus 4.6 was released a few months ago. Look at that jump!! I am shocked

While I think what Anthropic does is sad for the ecosystem, I wanna give Boris credit for doing what he can to soften the fallout. Today’s release will include some fixes for better cache use, to lower cost for API users.

New from the UK AISI Model Transparency team: we replicated Anthropic’s steering approach for suppressing evaluation awareness. Our most surprising finding: “”control”” steering vectors (about books on shelves!) can have effects as large as deliberately designed ones. 🧵

woke up and my mentions are full of these Both me and @davemorin tried to talk sense into Anthropic, best we managed was delaying this for a week. Funny how timings match up, first they copy some popular features into their closed harness, then they lock out open source.
