Last autumn I tried Qwen3-coder via CLI agents like trae to help add significant advanced features to a rust codebase. It consistently outperformed (at the time) Gemini 2.5 Pro and Claude Opus 3.5 with its ability to generate and re-factor code such that the system stayed coherent and improved performance and efficiency (this included adding Linux shared-memory IPC calls and using x86_64 SIMD intrinsics in rust).

I was very impressed, but I racked up a big bill (for me, in the hundreds of dollars per month) because I insisted on using the Alibaba provider to get the highest context window size and token cache.
