- Extended Context Window: Natively supports a 256,000-token context window, expandable to 1 million tokens.
- Agentic Capabilities: Optimized for agentic coding, enabling autonomous interaction with tools and developer environments.
- Benchmark Performance: Achieves state-of-the-art results among open models on challenging coding benchmarks like SWE-bench-Verified.
- Open-Source Accessibility: Released under an open-source license, promoting widespread adoption and modification.
Model Architecture and Capabilities
The Qwen3-Coder-480B-A35B-Instruct model is built upon a Mixture-of-Experts (MoE) design, featuring 160 experts with 8 activated per inference. This approach allows for state-of-the-art performance while significantly reducing computational overhead. Its architecture includes 62 layers and a substantial number of attention heads, contributing to its advanced reasoning and code generation abilities.
One of the model's most impressive features is its extended context window. It natively handles 256,000 tokens, and through context extrapolation techniques like Yarn, it can scale up to an astonishing 1 million tokens. This capability allows the model to process and understand entire codebases or extensive documentation in a single pass.
Performance Across Benchmarks
Qwen3-Coder-480B-A35B-Instruct has demonstrated exceptional performance across various coding benchmarks. It excels in agentic coding tasks, outperforming or matching proprietary models on suites like SWE-bench-Verified. Its proficiency extends to agentic browser use, tool utilization, competitive programming, automated testing, code refactoring, and debugging.
Qwen Code: An Agentic Command-Line Tool
In conjunction with the model release, Qwen has also open-sourced "Qwen Code." This command-line agentic coding tool is forked from Gemini Code and enhanced with custom prompts and protocols specifically tailored for Qwen3-Coder. Qwen Code facilitates seamless integration with developer workflows, enabling tasks such as tool integration, multi-turn code refinement, and context injection directly from the terminal.
Enterprise Implications and Developer Access
For enterprises, Qwen3-Coder-480B-A35B-Instruct offers a powerful, open-source alternative to closed-source models. Its ability to handle large codebases, its agentic capabilities, and its flexible deployment options make it ideal for various applications, including code review, CI/CD pipelines, and autonomous software development workflows. Developers can access the model via standard transformers pipelines or through the Qwen Code CLI, with integrations available for popular platforms like Ollama, LMStudio, and others.
