CAPA (No History): leaderboard
Metric: Executable success (%; share of the 300 held-out coding sessions solved within an eight-turn budget, a submission counting when the execution-grounded judge accepts it from the hidden tests and the reference solution, and a simulated user agent answering clarification questions; no history: the model sees only the new ambiguous request). Source: arxiv.org. Saturation forecast: Around December 2026. 12 models tracked.
