Qwen3-Coder: New Agentic Code Model with 1M Token Context
Qwen has announced Qwen3-Coder, a new agentic code model. Its most powerful variant, Qwen3-Coder-480B-A35B-Instruct, is a 480B-parameter Mixture-of-Experts model with 35B active parameters and supports up to 1M tokens with extrapolation.
Qwen3-Coder is available in multiple sizes, with the most powerful variant being Qwen3-Coder-480B-A35B-Instruct. This is a 480B-parameter Mixture-of-Experts model with 35B active parameters. It supports a context length of 256K tokens natively and 1M tokens with extrapolation methods. The source states it sets new state-of-the-art results among open models on Agentic Coding, Agentic Browser-Use, and Agentic Tool-Use, comparable to Claude Sonnet 4.
