Kimi-Dev-72B is Moonshot AI's open-weight 72B coding model built on Qwen2.5-72B-Base and mid-trained on approximately 150B tokens of software-engineering data. It was then cold-started with long chain-of-thought SFT trajectories and optimized by large-scale reinforcement learning on repository tasks, specializing in issue resolution via file localization and code editing with test-suite-verified rewards.
