Wait so Alibaba Qwen has just released ANOTHER model??

Qwen3-Coder is simply one of the best coding model we've ever seen.

→ Still 100% open source
→ Up to 1M context window 🔥
→ 35B active parameters
→ Same performance as Sonnet 4

They're releasing a CLI tool as well ↓ 

You can use the model for free on Qwen Chat:

1. Create a free account
2. Select Qwen3-Coder in the list
3. You can also upload files (codebase) 

Qwen-code is a CLI tool for agentic coding:

→ Forked from Gemini Code
→ Includes custom prompts and proper function call protocols
→ GitHub link: https://github.com/QwenLM/qwen-code 

Some useful links:

- Qwen3-Coder on Hugging Face: https://huggingface.co/Qwen/Qwen3-Coder-480B-A35B-Instruct

- Official blog post: https://qwenlm.github.io/blog/qwen3-coder/

Here are 2 (quite impressive) examples generated with Qwen3-Coder.

1. A 🔗edIn clone

As you can see the model is REALLY good when it comes to generating UIs. 

2. Asteroid Simulator

Something a bit more 'basic', but still amazing to see that Qwen3-Coder was able to generate:

- The sliders/parameters
- The impact and particles
- Import Three js and use it first try 

Comparison between Qwen3-Coder and other models on SWE Bench.

Key insights:

- Same score as Sonnet 4
- Very powerful for its size
- Better than virtually all proprietary models
- Probably much cheaper

Open source is winning!
