Yes. I do all my "production" inference either locally or on an encrypted spot aws g4dn instance for large models (which was a headache to work out and i still think i should work on tuning it to get more juice for it - its very expensive)

I do test some of the commercial models at times but honestly the only one I've used that outperforms on coding is claude 3.7 sonnet (claude 4 regresses on coding for me) and not by enough margin to not use qwen3-coder. They both get into endless logic loops when dealing with complex code beyond the trivial in which thrir bad vibes created dumb bugs - very profitable for the provider too when youre paying or are capped per token.
