From the video

Answers: How do you build a local AI cluster using multiple Mac Studios and Exo?

building local AI cluster with Mac Studio
using Exo software for AI clustering
testing Llama models on Mac Studio cluster
Thunderbolt networking for AI clusters
quantization and VRAM requirements for LLMs

What it concludes

Llama 3.2 1B runs successfully on a single Mac Studio with the Exo software.
Thunderbolt networking creates a performance bottleneck when connecting five Mac Studios into an AI cluster.
Mac Studios share 64GB of unified memory per machine, giving a total of 320GB of memory for GPU use in a 5-node cluster.
Nvidia GPUs with CUDA support outperform M-series Macs for running massive AI models due to specialized tensor cores and library support.
