Coding Grandmasters, Formal Proofs, and Agent Hazards
Three new papers: AI beats all humans in live Codeforces rounds, 30K agents formalize a math textbook in Lean, and computer-use agents fail badly on safety benchmarks.
Tao: Ideas Are Now Free - Math's Bottleneck Has Moved
Terence Tao argues AI has cut the cost of mathematical idea generation to near zero, but verification remains as hard as ever - and our existing academic infrastructure wasn't built for what comes next.
Leanstral Outperforms Claude Sonnet at Formal Code Proofs
Mistral's new open-source Lean 4 agent scores higher than Claude Sonnet on formal proofs at one-fifteenth the cost, raising the bar for trustworthy AI code generation.
Knuth Names Paper After Claude That Solved His Math Conjecture
Claude Opus 4.6 solved a directed graph decomposition conjecture Knuth had worked on for weeks in 31 guided explorations over roughly an hour. Knuth wrote the formal proof himself and titled the paper 'Claude's Cycles.'
