The Download: Unpacking Claude's Inner Workings and World Models

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. When Anthropic announced last week that it had found a new window into its models' 'internal thoughts' as they reason through answers, there was one colleague I had to talk to: senior editor Will Douglas Heaven. Aside from having a PhD in computer science, Will has spent a lot of time digging into what we can say about how AI models work.

I spoke with him about what we should take from Anthropic's new (and typically quirky) research. Here's what he had to say. This article is from The Algorithm, our weekly AI newsletter.

At a LinkedIn Live event today, MIT Technology Review will investigate how this technology could transform robotics and help unlock a new generation of intelligent machines. Join Will Douglas Heaven, our senior editor for AI, and Sam Sinha, founding AI researcher and head of world models at 1X Technologies, for the discussion. Register here to attend the free session at 9:30 PDT, 12:30 PM EDT, and 5:30 PM BST.
