- Kannan–Lovász–Simonovits (KLS) conjecture proved in two AI-assisted preprints: Song–Zhang's O(1) bound, then Bizeul–Klartag–Lehec ('most proofs … found by ChatGPT') ★★★★★
The KLS conjecture (1995), which says isoperimetry in convex bodies is governed up to a universal constant by half-spaces, was claimed resolved twice in three days. Zhao Song and Xinzhi Zhang (arXiv 2610.01447, Oct 2; v2 Oct 4) prove an O(1) bound on the KLS constant with GPT-6 Astra, GPT-5.6 Sol…
- Klartag and Moshe prove the ε-Dvoretzky conjecture (polynomial dependence on ε); the key probabilistic idea came from a ChatGPT discussion ★★★★
On Oct 2, 2026 Boaz Klartag and Shahar Moshe posted a short proof that the dependence on the accuracy ε in Dvoretzky's theorem is polynomial in 1/ε, not exponential. Their bound is n ≥ (C/ε)^((ℓ+1)/2)·|log ε| for an ℓ-dimensional section ε-close to an ellipsoid, through any interior point of any…
