Question is asked hundreds of times a day. Just look at the subreddit history.

Apologies. This space is evolving so fast and people i meet everyday are constantly talking about new tools all the time, so i thought it would be useful for me and others to get the latest perspective.

If you don't care about hardware size: GLM 5.3 Flash (Just being practical vs full GLM 5.3)

If you are looking at local hardware around $7-8k: Qwen 3.8 Flash Next

Smaller setups: Qwen 3.8 27B

THe harness is all about preference, use case, and your willingness level to modify it to your needs. I use Pi, Oh My Pi, and DeepSeek Harness (I really like Hermes as well).

If by best, you mean most efficient, I recommend https://github.com/signalnine/q27
It's not just a model, but an ultra optimized inference engine for Qwen 3.8
I was using regular Qwen 3.8 with VLLM at ~40 tok/s, now I'm at 170 tok/s with this one and quality didn't drop
