Qwen Coder 30B A3B is far better than Qwen Coder Next imo. I may have inference issues or it's just a problem with running Coder Next at IQ4 XS, vs Q8 for the earlier/smaller model but I don't find the 80B to be much better at coding, even in instruct mode, and the insane speed and low latency of the smaller model is way more useful. Good one-line completions often happen in 300ms.
