Navier-Stokes partial regularity machine-checked in Lean by 50-agent swarm in 36 hours
RexDouglass · x · 2026-09-22
Mathematicians Scott Armstrong and Vlad Vicol launched an agent swarm Friday night to formalize the classical Caffarelli-Kohn-Nirenberg partial regularity theorem for Navier-Stokes in Lean from scratch — done in about 36 hours.
- Orchestrated by Claude Fable 5.1, running up to 50 subagents at once
- Mix: 12 Luna-xhigh, 8 Astra-low, 10+ Leanstral, 10+ deepseek-4.1-flash, 8-10 Opus/Sonnet
- Upshot: many cheap low-powered subagents plus a strong orchestrator can formalize hard theorems fast
