Tongyi Qianwen releases Qwen3-Coder code model with performance comparable to Claude Sonnet4

On the morning of July 23, Alibaba Tongyi Qianwen released Qwen3-Coder today, claiming that this is the code model with the most proxy capabilities to date.It is reported that Qwen3-Coder has multiple sizes, the most powerful version of which is Qwen3-Coder-480B-A35B-Instruct. This is a MoE model with 480B parameter activation and 35B parameters. It natively supports the context of 256K tokens and can be extended to 1M tokens through YaRN. It has excellent code and agent capabilities.

Qwen3-Coder-480B-A35B-Instruct achieves the SOTA effect of open source models on Agentic Coding, Agentic Browser-Use and Agentic Tool-Use, which is comparable to Claude Sonnet4.

At the same time, Tongyi Qianwen also launched and open sourced a command line tool for agent programming: Qwen Code. Qwen Code was developed based on Gemini Code, and adapted prompt and tool calling protocols, so that Qwen Code can maximize the performance of Qwen3-Coder on agentic coding tasks.

In addition, Qwen3-Coder can be combined with excellent programming tools in the community, such as Claude Code, Cline, etc.
