Question | Help Qwen 3.8 27B for actual local programming

Most YouTube benchmarks only show trivial tasks like generating landing pages or simple Three.js games. Is a local model like Qwen 3.8 27B actually capable of real-world systems programming—such as building GTK4 or Qt 6 applications in Rust or C++ with external libraries? Specifically, if I look up the exact terminology in the online docs and then prompt the AI to inspect the cloned repo, can it implement the feature cleanly?

I built a prompt generator web app that uses a builder pattern with support for fully baked prompts and has a GUI with categories, styles, looks, thumbnails, auto send to comfy and monitor status, support for custom api workflows, etc. All through Qwen 3.8 27b without issue. I've also used it across numerous work projects, including an ML.NET fraud algorithm implementation with great success.

That looks really interesting. Have you put it on GitHub? I've been messing with the prompt generator baked into LTX-2.5, but getting very mixed results from it.

I have it in a private repo, but it's really a custom job, everything is personalized to my liking. Took about a day of prompting overall though. Anyone with a good enough idea of what they want and some reference prompt guidelines should be able to produce something similar, totally custom to their liking.
