The Rainier cluster will use Amazon’s custom-built AI chips, called Trainium 2, that compete with Nvidia’s graphics processors.

Amazon.com Inc. will provide artificial intelligence partner Anthropic with a massive cluster of homegrown chips it says will quintuple the startup’s current processing power.

The company’s megacluster of chips for artificial-intelligence startup Anthropic will be among the world’s largest, it said, and its new giant server will lower the cost of AI as it seeks to build an alternative to Nvidia.

AI startup Anthropic will collaborate with Amazon Web Services and put the supercomputer to work with its AI technology.
