>also why hyperscalers are paying folks to host gpu clusters in their homes

Source? There's definitely shady people paying people to host proxies, but hyperscalers doing it would be surprising.

My understanding of it so far is that it is at most, 50 or 100 houses as a test... It's a startup that wants to make it wide scale but hasn't got there yet.

Calling them a "hyperscaler" is a stretch. By all accounts it's some renewables startup that's trying to pivot into AI because obviously AI = $$$, and calling themselves a "hyperscaler" in the process. Calling them a "hyperscaler" makes as much sense as some guy who runs a homelab in his basement as a "datacenter".

My thoughts exactly. In the current environment you could slap "AI" on a potato and get $$$ for it.
