qwen3-coder-30b is surprisingly good for a smallish model, but it's not going to replace Claude Code. Maybe if you're using it for Python it could do well enough. I've been trying it with C code generation and it's not bad, but certainly not at Claude Code level. I hope they come out with a qwen coder model in the 60b to 80b range - something like that would give higher quality results and likely still run in the 15 tok/sec range which would be usable.
