**TL;DR:** OpenAI says an internal AI system found a faster theoretical algorithm for a fundamental logic problem. Outside researchers are organizing a public examination; their participation is not a certification of the result.

**Satisfiability** asks whether a set of true-or-false choices can satisfy a collection of constraints. The **Exponential Time Hypothesis** says that a central version of this problem cannot be solved in subexponential time in the number of variables.

OpenAI’s October 26 release claims to refute that hypothesis and publishes a manuscript and Lean formalization. **This would not, by itself, settle P versus NP or establish a practical speedup for today’s software.**

Russell Impagliazzo, Ramamohan Paturi and Ryan Williams explain why checking and understanding the claim is its own substantial piece of work:

I have inspected the release and the researchers’ letter, not independently checked the proof.
