OpenAI's bulk purchase of tens of thousands of Macs for reinforcement learning, combined with Anthropic's rental model, shows a concrete reallocation of training compute away from Nvidia's GPU monopoly toward Apple Silicon. Nvidia now views Apple as a primary competitive threat rather than a complementary player. This reflects a shift in the economics of large-scale model training, with major labs restructuring their hardware stacks mid-cycle. The move exposes both Nvidia's vulnerability in non-inference workloads and Apple's material advantage in power efficiency and unit cost for certain training tasks.
