People are running GPT OSS 120b at 46 tokens per second on Strix Halo systems, which is quite usable and a fraction of the cost of a 128GB NVidia or Apple system. Apple's GPU isn't that strong, so real competition to Apple and NVidia can be created.
On the flip-side, though: Running GPT-OSS-120b locally is "cool", but have people found useful, productivity enhancing use-cases which justify doing this over just loading $2000 into your OpenAI API account? That, I'm less sure of.
I think we'll get to the point where running a local-first AI stack is obviously an awesome choice; I just don't think the hardware or models are there yet. Next-year's Medusa Halo, combined with another year of open source model improvements might be the inflection point.
