Kimi-Dev-72B
Open-source 72B coding LLM tuned with large-scale RL on real repo patching.
About
Kimi-Dev-72B is Moonshot AI's open-source coding model, released June 2026. It is a 72B-parameter dense LLM built specifically for software engineering issue resolution, refined through large-scale reinforcement learning where it autonomously patches real repositories in Docker environments and only earns rewards when the full test suite passes.
It reached 60.4% on SWE-bench Verified, a new record among open-source models at release. The model and code are published on Hugging Face and GitHub with an open license, aimed at developers building coding agents and issue-resolution pipelines.
