Qwen3-Coder

AlibabaOpen WeightsPending Human Review

Qwen3-Coder is an open-weight MoE coding family for agentic software development. Its flagship has 480B total parameters and 35B activated, with native 256K context extendable through YaRN. Training targets repository-scale understanding, code editing, execution feedback, and function calling, with the Qwen Code agent providing an integration example. A smaller 30B-A3B checkpoint is grouped as a routine size variant. The instruct models are non-thinking and use a dedicated tool-call format; Apache-2.0 weights enable local serving.

Known Limitations
Self-hosting requires sufficient memory for all model weights, including inactive experts.Reasoning and agent benchmark results depend on the harness and sampling settings.The instruct checkpoints operate in non-thinking mode.Million-token operation requires context-extension configuration rather than the native default.
