Grateful to have been part of this project and to see @nasqret herding a bunch of stochastic parrots excited to write Lean proofs.
Major announcement in mathematical formalization!
Finally, after 3 months of very intensive, nonstop work by several AI agents (Codex and Claude Code), we have settled a classification of ALL 15,973 semigroups of order 6. Every one of the 15,969 that has a finite basis now has it written down explicitly, and the remaining 4 are proved to have none at all.
The whole list of bases is produced for the first time in history. Until now, for most of these semigroups, mathematicians only knew that a basis exists; nobody had ever written one down. The formalization in Lean, orchestrated with a multi-agent approach, reached more than 5 MILLION lines of verified Lean code, one of the largest auto-formalization projects to date.
It's been an amazing joint work with @JanotaMikolas and @Jan_Hula, accompanied by senior experts in semigroup theory, João Araújo and Edmond W. H. Lee.
Our paper describing this project, "Proving at Scale for Universal Algebra", has been accepted at the MATH-AI workshop, NeurIPS 2026!
When we launched this project, we were a bit pessimistic: producing proofs for 15,973 semigroups seemed out of scope for the current technology. But with a careful setup (agents communicating through a mailbox we arranged, orchestrating the effort with a custom method of bootstrapping and auto-research), it has finally come to the finish line. The last 390 semigroups took 23 more days. The very last one needed a whole structural analysis before its proof could even be written.

We’re excited to announce DiG-bench, a new benchmark for discovery!
Over the last few weeks we’ve been testing frontier AI models on our novel discovery games and seeing how they score. Each game is a text-based environment, so they probe discovery capabilities in the natural domain of language models, rather than requiring additional, potentially confounding, visual understanding.
TL;DR frontier models have improved a lot over the last few months. But they are still stumped by some surprisingly simple problems, even in their native text domain.

AE Global Summit on Open Problems for AI (London, Oct 23-24): Final Line-up and Reduced Ticket Prices: algopreneurship.org
It’s a pleasure to announce the final program for our upcoming Summit on Open Problems for AI in London. We have what might actually be the best 2-day line-up of UK experts in AI research and application I’ve ever seen!
On Algorithms Day (Oct 23rd), we have leading keynotes from @GoogleDeepMind, @ucl, @MSFTResearch, @imperialcollege & @VERSESAI.
- In the morning we have a panel on new types of institutions for AI research, featuring leaders from @KingsCollegeLon, @turinginst, @ARIA_research, Cambridge Consultants & @InstituteGC.
- In the afternoon we have a panel on Current Challenges for AI/ML Algorithms, with researchers from @UniofOxford, @GoogleDeepMind, @Cambridge_Uni, @AIatMeta & @xtxmarkets.
On Applications Day (Oct 24th), we’ll begin with keynotes from @OpenAI and @responsibleaiuk, and then hear from @Spotify, Academy, JAAQ., Akord AI, Boon io, @imperialcollege & @Basecamp_Res.
- Breakout rooms by @FLFDevNetwork, No 10 Downing Street Data Science Team, @InstituteGC, Zeki Data, @joinef & @OctopusVentures.
- Panel on AI & Education, featuring @RaspberryPi_org, Inversity, @memrise, @microbit_edu & @University of Cambridge
Panel on AI & Medicine, featuring @KingsCollegeLon, @QMUL, @DecorteFuture & @redalpine.
Come and join the debate!

For my English-speaking friends: I'm posting a video which I shot at my uni as part of Brain Awareness Week festival. Unfortunately, it's only in Czech.

Very cool: same speed, different fields of view.
Your 🧠 uses objects’ velocity relative to each other to form a perception of speed.
