OpenAI buys thousands of Mac minis to train AI agents

OpenAI has purchased tens of thousands of Mac mini and Mac Studio systems for reinforcement learning and computer-use agent training, while Anthropic is renting similar hardware via AWS. The shift reflects demand for Apple’s unified memory architecture for local multi-session and agent workloads beyond traditional GPU clusters. The unexpected enterprise uptake has contributed to strong Mac revenue growth and earlier-than-usual hardware refreshes.
