Amazon's $11 billion AI data center is operational! Exclusively for partners Anthropic to train large models

According to Zhitong Finance APP, Amazon (AMZN.US) officially launched its $11 billion Rainier data center project in Indiana this Wednesday. The project was initially announced in December 2024 and will be dedicated to training and running the models of Anthropic, a leader in the field of generative artificial intelligence.

Amazon has invested in Anthropic multiple times, with the latest financing round occurring in September 2024, valuing the company at $183 billion.

The Rainier project spans 1,200 acres in Indiana and is equipped with approximately 500,000 Amazon-developed Trainium2 chips.

Amazon added in a statement that it will ultimately accommodate nearly 1 million Trainium2 chips.

Ron Diamant, an AWS engineer and chief architect of the Trainium chip, stated in the announcement, "The Rainier project is one of the most ambitious projects AWS has undertaken to date. It is a massive and unique infrastructure project that will lead the way for the next generation of AI models."

Amazon explained that the data center will not only run Anthropic's existing models but will also be used for updated versions of Anthropic's generative AI chatbot, Claude.

Before the unveiling ceremony, Anthropic announced earlier this month that it would expand its collaboration with Google to utilize Google's tensor processing units. Anthropic stated that the expanded deal is worth "tens of billions of dollars" and is expected to bring online computing power exceeding 1 gigawatt by 2026.

Anthropic also added that it remains "committed" to collaborating with its primary training partner and cloud service provider, Amazon
