About
A self-improving AI framework that autonomously tunes its own performance.
Why it made the leaderboard
A self-improving AI framework that tunes both sides of the system: the harness (prompts, tools, execution environment) and the model weights, coordinated by multiple agents. The team reports 70.1% on LawBench against a 45% prior state of the art, 14x Triton kernel speedups, and a #1 ranking on OpenAI's MLE-Bench.
