Rumored Math Breakthrough by GPT-5.6

新智元 · wechat · 2026-07-15

OpenAI officially claims that GPT-5.6 Sol Ultra proved the "Circuit Double Cover Conjecture," which has puzzled the math community for 50 years, in under an hour. The task wasn't completed by a single model alone; instead, a system of 64 concurrent agents collaborated to produce the proof, ultimately formatted into a paper with the help of Codex.

The article details this system's organization: the first round required exploring multiple completely different proof paths; a "picket line" was set up to rigorously refute each candidate proof; and it mandated specific lemmas, constructions, and equations to avoid empty talk. The author attributes this breakthrough to parallel test-time compute (TTC): breaking down long-duration reasoning into a massive concurrent search, thereby compressing an exploration that might otherwise take much longer into under an hour.
