teortaxesTex · x · 2026-07-11

GPT-5.6 Sol Ultra is now in general availability.

The official account also shared a demo where the model utilized 64 subagents to generate a proof for the famous Cycle Double Cover Conjecture in under an hour, publishing both the prompt and the proof.

The key takeaway isn't just the final result, but how it demonstrates the model's post-training ability to leverage multi-agent collaboration for high-level reasoning in complex tasks.
