Investing.com -- Amazon.com announced on Wednesday the launch of its compute cluster project called Rainier, revealing that AI firm Anthropic will utilize more than a million chips of the infrastructure by the end of 2025.

The tech giant began Project Rainier last year to build an artificial intelligence compute cluster distributed across multiple data centers in the United States. The computer system currently incorporates nearly half-a-million of Amazon’s in-house Trainium2 chips.

As artificial intelligence models become more advanced, cloud providers like Amazon’s Web Services are expanding their data center plans to address the increasing demand for massive compute capacity.

Anthropic, which receives backing from Amazon, is using Project Rainier’s compute cluster to build and deploy its AI model Claude. The AI company will scale to use more than 1 million Trainium2 chips across Amazon’s Web Services by the end of this year.

Amazon stated that Rainier’s compute power will also support future versions of the Claude AI model.
