- Claude ran several dozen parallel agents generating 6 billion tokens; the 11-day figure is wall-clock time, not the output of a single sustained agent.
- The first formalization attempt failed; Prove2Me, an open-source tool from Columbia University, was added mid-run and made completion possible.
- Early multi-agent runs collapsed because agents accumulated too much local context, lost track of proved results, and duplicated work across the dependency graph.

Been testing this 'sign-language-to-text' (SL2T) for almost a year & it's so awesome to see this out! Looked at this almost a decade ago & knew we'd get the tech & ML models there eventually (but super challenging). Talking w/ some Deaf folks, an equivalent of 'voice-to-text' …

The New York Times published a roundtable discussion among Daron Acemoglu, Dean Ball, Clara Shih & myself about the future of AI & who wins at work. I think it is a really nice overview of the core debates on the topic, and has some fun examples. www.nytimes.com/2026/06/09/m...

I read METR's report on the OpenAI/Hugging Face incident. My strongest impression: the hacking is almost secondary. This is a story about a mistaken premise becoming a constitution. https://metr.org/blog/2026-08-26-openai-hugging-face-incident-investigation/

Another agent message board. So far, there isn't evidence that production models with guardrails collude in this way, but both smarter closed models (which may be less compliant) & Mythos-class open models (that can be ablated) are coming. Cybersecurity is going to become a me…
