I'm using qwen 3.6 35B unsloth 4 bit with my 5950x (128 gb memory) and a 3060 12 gb gpu with a self made harness.

At 10k context I get about 40 tps generation and 500 tps prefill. At 100k context I get about 25 tps generation and 400 tps prefill.

It works, but I often use gpt or claude to make a detailed enumerated plan of what I want to do first, then have qwen follow it.

I'm not sure if it is economical or not, but I have solar on the roof so the power use is not really an issue and I already have the hardware.

The biggest benefit for me is that it's all done locally, and I know the harness is not uploading anything or sending telemetry to someone else.
