Qwen3 Coder 480B A35B is Alibaba's largest coding-specialized MoE model with 480B total and 35B active parameters, native 256K token context extended to 1M.
Capabilities, design details, and architectural traits
Qwen3 Coder 480B A35B-Instruct is Qwen's most powerful agentic code model, designed for autonomous software engineering, repository-level understanding, and multi-turn tool use with interactive reasoning.
Qwen3 Coder 480B A35B sets new standards for open models in agentic coding and browser-use tasks:
| Distinctive Trait | Why It Matters | How It Works |
|---|---|---|
| 35B activated parameters | Efficient inference for massive 480B model | Uses 8 experts out of 160 total during inference, activating only 35B of 480B per forward pass |
| Native 256K token context | Repository-scale understanding in single pass | Processes 262,144 tokens natively, extended to 1M tokens with Yarn extrapolation for vast codebases |
| Specially designed function call format | Agentic coding requires precise tool invocation | Supports Qwen Code, CLINE, and other platforms with dedicated function call structure for tool use |
| Non-thinking mode only | Consistent behavior for coding tasks | Does not generate blocks, spec enable_thinking=False not required for predictable output |
| State-of-the-art agentic performance | Open models rival proprietary alternatives | Achieves results comparable to Claude Sonnet 4 on Agentic Coding, Agentic Browser-Use, and Agentic Tool-Use benchmarks |
Qwen3 Coder 480B A35B was built to deliver autonomous coding agent capabilities that manage complex workflows beyond basic code generation, supporting interactive multi-turn reasoning and tool use across diverse programming ecosystems.
