Alibaba's Qwen team announces Qwen3-Coder, a new agentic code model, with its most powerful variant Qwen3-Coder-480B-A35B-Instruct (480B parameters, 35B active, MoE) supporting 256K native context and 1M with extrapolation, achieving state-of-the-art results among open models on agentic coding, browser-use, and tool-use tasks, comparable to Claude Sonnet 4.

## Evidence

Verbatim from https://qwenlm.github.io/blog/qwen3-coder/:

> Qwen3-Coder is available in multiple sizes, but we’re excited to introduce its most powerful variant first: Qwen3-Coder-480B-A35B-Instruct — a 480B-parameter Mixture-of-Experts model with 35B active parameters which supports the context length of 256K tokens natively and 1M tokens with extrapolation methods, offering exceptional performance in both coding and agentic tasks.
