The development
OpenAI's GPT-5.6 has crossed a threshold in mathematical problem-solving, enabling a mathematician named Bartosz to tackle previously intractable proofs. This represents a concrete capability expansion beyond prior model generations, signaling that frontier LLMs are now competitive with specialized mathematical reasoning tasks. The shift matters for research communities reliant on computational proof assistance and suggests the model's reasoning depth has matured enough to handle open-ended mathematical discovery, not just verification or tutoring.

Modelwire analysis
Skeptical readOur AI-generated reading of the wider context and the next developments to watch.
The framing of 'previously unsolvable' is doing a lot of work here and deserves scrutiny: we don't know whether Bartosz is tackling open conjectures, problems that were merely tedious, or problems that existing proof assistants like Lean or Coq could already handle with enough human scaffolding. OpenAI produced this video themselves, which means it functions as a case study, not a peer-reviewed capability evaluation.
This is largely disconnected from recent activity in our archive, as we have no prior coverage to anchor it to. It does belong to a longer-running conversation in the formal mathematics community about whether LLMs can contribute to genuine discovery versus assisted verification, a distinction that researchers working with tools like AlphaProof and Lean-based assistants have been careful to draw. That context matters here because the bar for 'solving' a problem varies enormously depending on who is setting it.
Watch whether Bartosz or OpenAI publishes the specific problems and proofs in a venue where the mathematics community can assess them independently. If the work appears in a preprint or journal with the model's contributions clearly documented, the claim earns serious weight; if it stays in promotional video format, treat it accordingly.
