Definition: Project Rainier


Amazon's supercomputing center in New Castle, Indiana, near South Bend. Operational at the end of 2025 with nearly a half million Trainium2 chips, Rainier is used to train Anthropic's Claude models. With a million chips projected, Rainier will use two gigawatts of electricity.

Not GPUs, Technically
Although the Trainium chips perform the same mathematical processing as NVIDIA and AMD GPUs do, the Amazon chips are technically not GPUs because they were designed from scratch for AI.



A Pink Datacenter
One might not think the color pink when it comes to AI datacenters, but Amazon's Rainier is the exception. On 1,200 acres of land, Rainier is one of the largest AI processing centers in the U.S. (Image courtesy of Amazon.com.)
