【Just now, Alibaba open-sourced Qwen3-Coder, a programming model at the level of Claude】

Alibaba open-sourcing is starting to compete again!

Just now, Alibaba released Qwen3-Coder, which has topped the global open-source models in programming capabilities. Even more impressive is that it surpassed GPT-4.1, a closed-source model, and can stand on par with Claude 4, the current strongest programming model.

The most exciting part is its actual performance — it's said that novice programmers can complete the work of experienced programmers in a week within just one day using it, and it can generate a brand website in as fast as 5 minutes. This efficiency is simply mind-blowing.

From a technical perspective, it's also very interesting. It's the first code model in the Qwen series to adopt a mixture of experts (MoE) architecture. The total number of parameters reaches 480B, but only 35B parameters are activated. It natively supports a context length of 256K tokens and can be extended up to 1M length. It was pre-trained on 7.5T data, of which 70% are code, no wonder its programming capabilities are so strong.

The performance in terms of Agent capabilities is even more outstanding. In Agent evaluations such as WebArena (browser calling) and BFCL (tool calling), Qwen3-Coder directly set new records for open-source models, even surpassing GPT-4.1. In SWE-Bench, an evaluation that examines a model's ability to independently solve programming tasks, it achieved the best open-source results, comparable to the level of Claude 4.

The most practical aspect is its ability to handle complex long tasks. It can plan comprehensively and autonomously, call various tools to deeply research problems. Test results show that it can call several times more tools than Claude, with excellent results. Industry insiders have already said that the open-source Qwen3-Coder may replace expensive Claude and become the most popular programming model in the Agent field.

Currently, it has been open-sourced on platforms such as ModelScope and HuggingFace, and global developers can use it for free. It will soon be integrated with Tongyi Lingma, and the API will also be available on Alibaba Cloud BaiLian.

Alibaba also specially open-sourced the command-line tool Qwen Code, which can better leverage the potential of agent-style programming. Moreover, the API can be used in conjunction with tools like Claude Code and Cline.

Throughout the years, Claude has always been the top of the programming model field. This time, Alibaba open-sourced a programming model of this level. What do you think? Welcome those who have already used it to comment.
