Qwen3-Coder
Qwen3-Coder is Alibaba Cloud's dedicated coding model, released on July 22, 2025. The flagship variant, Qwen3-Coder-480B-A35B-Instruct, is a mixture-of-experts model trained on 7.5 trillion tokens across 358 programming languages, with 70% of the training data being code. It supports 256K tokens of native context, extensible to 1M tokens with extrapolation, making it suited to repository-scale tasks and multi-file agentic workflows.

Core Features
- 480B/35B MoE architecture: 480B total parameters with 35B active per token, using 160 experts with 8 activated per inference step.
- 256K native context: natively processes 256,000 tokens, with extrapolation support up to 1,000,000 tokens.
- 358 programming languages: trained on a broad code corpus covering mainstream and niche languages.
- Agent RL post-training: long-horizon reinforcement learning trains the model to solve real-world tasks through multi-turn tool interactions.
- Apache 2.0: weights are available for commercial use and fine-tuning.
Benchmarks
| Benchmark | Score |
|---|---|
| SWE-Bench Verified | 69.6% |
SWE-Bench Verified scores are state-of-the-art among open models at release, comparable to Claude Sonnet 4.
