It helps 256K token context lengths natively, with extrapolation as much as 1 million tokens utilizing YaRN (Yet one more RoPE extrapolatioN) — a way used to increase a language mannequin’s context size past its unique coaching restrict by modifying the Rotary Positional Embeddings (RoPE) used throughout consideration computation. This capability permits the mannequin to grasp and manipulate total repositories or prolonged paperwork in a single go.
Designed as a causal language mannequin, it options 62 layers, 96 consideration heads for queries, and eight for key-value pairs. It’s optimized for token-efficient, instruction-following duties and omits help for <suppose> blocks by default, streamlining its outputs.
Excessive efficiency
Qwen3-Coder has achieved main efficiency amongst open fashions on a number of agentic analysis suites:
- SWE-bench Verified: 67.0% (commonplace), 69.6% (500-turn)
- GPT-4.1: 54.6%
- Gemini 2.5 Professional Preview: 49.0%
- Claude Sonnet-4: 70.4%
The mannequin additionally scores competitively throughout duties similar to agentic browser use, multi-language programming, and power use. Visible benchmarks present progressive enchancment throughout coaching iterations in classes like code era, SQL programming, code modifying, and instruction following.
Alongside the mannequin, Qwen has open-sourced Qwen Code, a CLI instrument forked from Gemini Code. This interface helps operate calling and structured prompting, making it simpler to combine Qwen3-Coder into coding workflows. Qwen Code helps Node.js environments and might be put in by way of npm or from supply.
Qwen3-Coder additionally integrates with developer platforms similar to:
- Claude Code (by way of DashScope proxy or router customization)
- Cline (as an OpenAI-compatible backend)
- Ollama, LMStudio, MLX-LM, llama.cpp, and KTransformers
Builders can run Qwen3-Coder regionally or join by way of OpenAI-compatible APIs utilizing endpoints hosted on Alibaba Cloud.
Publish-training strategies: code RL and long-horizon planning
Along with pretraining on 7.5 trillion tokens (70% code), Qwen3-Coder advantages from superior post-training strategies:
- Code RL (Reinforcement Studying): Emphasizes high-quality, execution-driven studying on numerous, verifiable code duties
- Lengthy-Horizon Agent RL: Trains the mannequin to plan, use instruments, and adapt over multi-turn interactions
This section simulates real-world software program engineering challenges. To allow it, Qwen constructed a 20,000-environment system on Alibaba Cloud, providing the dimensions mandatory for evaluating and coaching fashions on advanced workflows like these present in SWE-bench.
Enterprise implications: AI for engineering and DevOps workflows
For enterprises, Qwen3-Coder affords an open, extremely succesful various to closed-source proprietary fashions. With robust leads to coding execution and long-context reasoning, it’s particularly related for:
- Codebase-level understanding: Excellent for AI programs that should comprehend massive repositories, technical documentation, or architectural patterns
- Automated pull request workflows: Its capability to plan and adapt throughout turns makes it appropriate for auto-generating or reviewing pull requests
- Instrument integration and orchestration: Via its native tool-calling APIs and performance interface, the mannequin might be embedded in inner tooling and CI/CD programs.
