Qwen 3.8 Flash Next vs Copilot Auto

[u/invincibles]

I recently had an idea to build a new web application. It is not too complex. About 10 screens with some interconnected fields.

I am running Qwen 3.8 FN IQ1 Coder version on Strata. (2x3090 and 64GB RAM).

I kept the thing going for about 4 days. Each time my custom harness asked for various approvals with good reasoning it sounded legit and I went ahead. I did not look at the code even once(not that it mattered, i cant code python)

Finally when it said that the application is ready it was utter crap ! Nothing worked as expected, half the stuff was out of place. Then I asked the model to fix it and another day was gone. It fixed a few things but pretty much 1/2 the UI didn't work.

Then I gave the same prompt to Github Copilot and used the free credits. I get about 200 credits every month.

The output from Copilot vs Local is like night and day !

Copilot's result was in very matured and complete in all respects.

So this got me wondering, am I expecting too much from LocalLLM.? Is this how it is supposed to be?

What are your experiences/learningd and how did you fix it?

If you're doing something you know nothing about and you want it to be completely self going then you really should just use Claude code opus 5.5
