I regret building this $3000 Pi AI cluster
ordered a set of 10 Compute Blades in April 2023 (two years ago), and they just arrived a few weeks ago. In that time Raspberry Pi upgraded the CM4 to a CM5, so I ordered a set of 10 16GB CM5 Lite modules for my blade cluster.
So discounting the fact we're only talking CPUs, I don't think any hyperscalers are looking to swap out a few thousand AMD EPYC systems for 10,000+ Raspberry Pis :) Like the only real world use case besides learning is for CI jobs or high security edge deployments, where you're not allowed to run multiple things on one server. But I will keep it going, knowing it's definitely easier to maintain than the 1,050 node Pi cluster at UC Santa Barbera, which to my knowledge is still the world's largest!
