AI Labs Deploy Massive Mac Mini and Mac Studio Clusters for Agent RL

AI labs like OpenAI and Anthropic are shifting toward deploying large on-premise clusters of Apple Mac mini and Mac Studio M5 Ultra machines. Reinforcement learning for computer-use agents requires thousands of parallel, lightweight operating system sandboxes rather than dense GPU interconnects. Unified memory setups with up to 512GB RAM allow local model hosting and headless browser execution at a fraction of cloud VM rental costs.
