Why it matters

Zoneraich's experiment moves coding agents into mathematical research, where parallel search can generate candidates quickly but public proofs and expert review still determine validity.

Cognition's Devin generated proofs and counterexamples for four graph conjectures — Cognition builder Jared Zoneraich ran roughly five Ultra-mode agents per problem, with one counterexample checked in Lean.

Jared Zoneraich (@imjaredz), a Builder in Residence at Cognition, said on July 23rd that Devin produced proofs or counterexamples for four long-open graph theory conjectures across three assignments.…
