Qwen3-Coder-30B-A3B-Instruct is good I think for in line IDE integration or operating on small functions or library code but I dont think you will get too far with one shot feature implementation that people are currently doing with Claude or whatever.

I have been adding a one shot feature to a codebase with ChatGPT 5.3 Codex in Cursor and it worked out of the box but then I realised everything it had done was super weird and it didn't work under a load of edge cases. I've tried being super clear about how to fix it but the model is lost. This was not a complex feature at all so hopefully I'm employed for a few more years yet.

I could be doing something wrong, but I have not had any success with one shot feature implementations for any of the current models. There are always weird quirks, undesired behaviors, bad practices, or just egregiously broken implementations. A week or so ago, I had instructed Claude to do something at compile-time and it instead burned a phenomenal amount of tokens before yeeting the most absurd, and convoluted, runtime implementation—- that didn’t even work. At work I use it (or Codex) for specific tasks, delegating specific steps of the feature implementation.

The more I use the cloud based frontier models, the more virtue I find in using local, open source/weights, models because they tend to create much simpler code. They require more direct interaction from me, but the end result tends to be less buggy, easier to refactor/clean up, and more precisely what I wanted. I am personally excited to try this new model out here shortly on my 5090. If read the article correctly, it sounds like even the quantized versions have a “million”[1] token context window.

And to note, I’m sure I could use the same interaction loop for Claude or GPT, but the local models are free (minus the power) to run.

[1] I’m a dubious it won’t shite itself at even 50% of that. But even 250k would be amazing for a local model when I “only” have 32GB of VRAM.
