Alibaba Qwen 3 Coder Open-Source AI Model Introduced With Agentic Capabilities

Alibaba’s Qwen crew launched a brand new synthetic intelligence (AI) coding fashion on Tuesday. Dubbed Qwen 3 Coder, the fashion comes with a number of agentic features together with agentic coding, agentic browser-use, and agentic tool-use. The researchers have launched just one variant of the fashion to this point, the Qwen3-Coder-480B-A35B-Instruct, which is probably the most tough variant within the circle of relatives. In phrases of efficiency in coding, Alibaba’s AI crew claims the open-source fashion is similar to Anthropic’s Claude Sonnet 4 fashion. The new huge language fashion (LLM) is to be had to obtain in the neighborhood.

Qwen 3 Coder Model With Agentic Capabilities Released

In a blog post, the researchers detailed the brand new agentic coding instrument. Available in open-source, folks can obtain the weights from Qwen’s Hugging Face listing and GitHub listing. The fashion is to be had with a permissive Apache 2.0 licence which permits for each instructional and business utilization. Alongside the fashion, an open-source command-line instrument dubbed Qwen Code could also be to be had for agentic coding.

Coming to the fashion, the Qwen 3 Coder is a mixture-of-expert (MoE) fashion with 480 billion parameters. Out of that, the fashion purposes with 35 billion lively parameters and a context period of two,56,000 tokens natively. The context window can also be expanded to 1,000,000 tokens the use of extrapolation strategies. The researchers highlighted that the fashion helps agentic coding, agentic browser-use, and agentic tool-use.

The corporate claims that Qwen 3 Coder accomplished state of the art (SOTA) efficiency amongst open-source fashions at the SWE-Bench Verified benchmark. Here, SOTA refers back to the very best ranking which was once up to now impossible via every other fashion. The Qwen crew mentioned this ranking was once accomplished via making a scalable device the use of Alibaba Cloud’s infrastructure that might run 20,000 impartial environments in parallel.

To allow agentic coding, the crew has additionally launched the Qwen Code command-line instrument. Built from Gemini Code, it’s been provided with customized activates and serve as calling protocols. These functionalities permit the AI fashion not to best write and edit code but additionally to deploy and execute it in an built-in building surroundings (IDE).

While Qwen Code natively helps Qwen 3 Coder AI fashion, it can be built-in with the OpenAI device building equipment (SDK) when calling LLMs. On the opposite hand, the Qwen coding fashion can be used with Claude Code. But builders will wish to request an API key on Alibaba Cloud Model Studio platform.
