OpenAI has reportedly bought tens of thousands of Apple Mac mini and Mac Studio units for reinforcement learning and AI agents that operate computers. The purchases have contributed to shortages, with some buyers facing longer delivery times. Apple is also reported to have moved up refreshed Mac launches as demand for AI-capable hardware grows.

OpenAI has quietly purchased tens of thousands of Apple Mac mini and Mac Studio units over the past several months to train reinforcement learning systems and AI agents that operate computers on their own. The buying spree is being blamed for supply shortages that have pushed Apple to release refreshed versions of both machines earlier than expected.

Why AI labs are turning to Apple's desktops

The Information reports that OpenAI's Mac purchases are separate from the cloud GPU clusters it typically leases for large-scale model training, pointing instead to a preference for Apple's compact desktops for specific reinforcement-learning and computer-use-agent workloads. Apple's unified memory architecture, which allows the CPU, GPU and neural engine to draw from a shared memory pool, has made the Mac mini and Mac Studio well suited to running these kinds of AI tasks efficiently compared with conventional desktop setups.

Anthropic, by contrast, is said to be accessing the same class of hardware without buying it outright, instead renting Mac minis through Amazon Web Services for similar workloads, per the same report.
