Amazon’s Mega AI Data Center Powers Anthropic’s Claude Model

Amazon has switched on one of the world’s biggest AI data centers to support Anthropic’s Claude chatbot, marking a major step in the race to build next-generation artificial intelligence systems.

The huge facility, built under Amazon’s Project Rainier, is designed to train and run powerful AI models at massive scale. It reportedly uses hundreds of thousands of Amazon’s custom Trainium 2 chips, with plans to expand to more than a million chips by the end of the year.

The new data center stretches across several U.S. sites, including Indiana and Pennsylvania, and requires enormous power and high-speed fiber-optic networks. Everything is built to push heavy AI workloads — such as training large language models — faster and more efficiently.

Anthropic, the company behind the Claude AI assistant, will be the first major user of the facility. With this infrastructure, Anthropic aims to build smarter and more reliable AI models for both businesses and everyday users.

Amazon says the investment shows its commitment to leading the global AI infrastructure market. While tech companies face higher energy costs and economic uncertainty, Amazon is doubling down on long-term AI growth.

The launch also highlights rising competition in AI computing. Google, Microsoft, and Nvidia are also building advanced data-center systems to power future AI applications. But Amazon’s new project gives it a strong foothold in the rapidly expanding AI hardware and cloud market.
