The shift from traditional GPUs is tied to Apple’s unified memory architecture, which gives the CPU, GPU, and Neural Engine shared access to memory, reducing data transfers during agent training.

Reinforcement learning combines inference with interaction with an environment. Many compact Macs can therefore cost less than GPU clusters built for matrix-heavy workloads.

Anthropic reportedly uses Mac mini too, renting them from AWS. Demand has stretched delivery times for high-memory Mac mini and Mac Studio configurations to weeks or months.
