Moonshot AIOpen WeightsPending Human Review

Kimi-Dev is a 72B open-weight language model specialized for software issue resolution. It builds on Qwen2.5-72B and uses reinforcement-learning-based self-play with coding and testing tasks to improve repository-level software engineering. The released checkpoint targets bug fixing and code editing under an agent harness rather than merely writing isolated snippets. MIT weights and inference examples support self-hosted experiments. End-to-end issue-resolution performance depends on the surrounding tools, tests, and execution environment.
