I'll look into it, though seeing "contact us" always makes me think they're not going to sell a single unit to a home user. (With that said, Groq probably wouldn't either. You can technically buy LPUs for 20k each, without an expectation of support, but it takes tens of them to run Mixtral.)
Tenstorrent also looks incredibly Python-specific (as in, everything including their SMI seems mostly Python-based) which doesn't seem promising?
