OpenAI Internal Model Solves 5 More Erdős Problems — Capability Milestone for Unreleased System
A r/singularity post (250↑, 58cmts) reports that an internal (unreleased) model at OpenAI has solved five additional Erdős problems beyond what GPT-5.2 achieved in January. This builds on the earlier breakthrough where GPT-5.2 Pro solved Erdős Problem #397 (verified by Terence Tao), and Tao noted AI tools have helped solve ~100 Erdős problems since October 2025. The claim of an internal model exceeding public model capabilities suggests OpenAI's research frontier continues advancing ahead of commercial releases in mathematical reasoning.
