OpenAI Might Be Hiding More Powerful Models
basedjensen · x · 2026-07-11
Based on claims that GPT-5.6 Sol Ultra proved a mathematical conjecture, a post infers that if this was achieved using a publicly available model today, OpenAI must have possessed an even stronger internal model at least two months prior.
The original post notes that the unit distance problem results were announced on May 20, with at least a week-long gap between the discovery and the public announcement, indicating OpenAI researchers needed time for internal verification. The core takeaway is the potential existence of a significant capability gap between public releases and unreleased internal models.
