Qwen 3.6 27B and 3.8 27B are the darlings of local inference at the moment.
The only other thing anyone is using is Qwen 3.8 Flash Next, only by memory-rich people.
Depending on which benchmarks you believe, these models (and the Ornith 1.5 finetune of Qwen 35B-A3B) are competitive at about Opus 4.5 to 4.7 level. That matches my experience in real tasks over the last few months.
Not bad for something you can run at home for a couple of thousand dollars.
