Amazon’s biggest AI data center is now operational in Indiana, with half a million AWS Trainium 2 chips entirely devoted to powering OpenAI rival Anthropic.

CNBC talked to AWS CEO Matt Garman about the project, and went to New Carlisle, Indiana, to ask locals about the impact — and for a first ever on-camera tour inside the largest cluster of non-Nvidia chips in the world.
