Frontier LLMs Successfully Prove the Existence of Nonsofic Groups
repligate · x · 2026-08-01
A recent tweet discussed a new breakthrough by frontier Large Language Models in the field of advanced mathematical proofs. Just before the release of a relevant paper, existing models (such as Fable and 5.6 Sol) were able to prove the existence of nonsofic groups.
The models employed different technical paths during the proof process: for instance, Astra used prefix geometry, while Sol and Fable utilized explicit matrix algebra. Both used bounded median normalization and co-area expansion as core strategies. Furthermore, Sol and Fable defined a new infinite nonsofic group using only finitely many generators and relations.
