Traditional coding benchmarks do not reflect how software is actually built and maintained.
That's why we built a new benchmark, APEX-SWE, in partnership with @cognition. It measures whether AI models can perform complex, real-world software engineering work to ship systems that work and debug them when they don't.
@OpenAI GPT 5.3 Codex (High) tops the leaderboard at 41.5% on Pass@1.
