This is a review: I have the Orange PI AI studio thing, 96gb ram and two NPUs, using gpustack, the best I've gotten is qwen3-30b-a3b with around a 100k context window - runs at 25-28tps
There are some weird quirks with it, I've mostly been constrained to using MindIE as a backend which doesn't support all models. I've tried vLLM but it tends to crash and complain it can't talk to both NPUs.
Overall I'm pretty happy with it though
