Meta buys millions of Amazon's custom AI chips, signaling shift away from GPUs toward cheaper processor alternatives

Meta signed a deal to purchase a large quantity of Amazon's custom-built CPUs (standard processors, not the graphics chips most AI companies use) for running AI agents (AI systems that make decisions and take actions without human intervention for each step). This marks a major bet on an alternative to the expensive, hard-to-find GPUs (graphics processors) that have dominated AI chip demand.

Amazon's CPUs cost less and are easier to source than the specialized GPU chips from NVIDIA that every tech company is competing for. For repetitive AI tasks like answering customer support questions or processing data, CPUs may be 'good enough' — meaning Meta can handle more workloads for less money and without waiting for scarce chip inventory.

This forces the entire AI industry to rethink chip strategy. If Meta — one of the world's largest AI spenders — can do useful work on cheaper, more-available CPUs instead of premium GPUs, other companies will follow, which could finally ease the global shortage of AI chips. For businesses waiting months to access GPU capacity, this opens a new path forward.
