Honestly surprised to hear that GPT OSS 20B runs slow on mac hardware. It's absolutely one of the fastest models I've run on local GPUs for its size, but only tried Nvidia cards.

Edit: TIL it is MoE and only has 3.6B active, explains a lot.

Yeah, I'm probably wrong there. GPT OSS 20B is certainly much faster than some other models I've tried. I actually gave GPT OSS 20B a few prompts just now and it seems to respond as fast or faster than Qwen 3.5 9B. But I needed many more prompts for GPT OSS 20B to complete my contrived task, so progress felt much slower.
