AWS Stargate-smashing Rainier megacluster goes live
"Never mind Sam Altman's Stargate, which is just beginning to open its portal to distant AI-fueled worlds: Amazon's competing mountain of AI compute power is already up and running. Amazon Web Services today announced that Project Rainier, its Stargate-rivaling AI "UltraCluster", is now up and running, with "nearly half a million" Trainium2 chips serving the massive machine across multiple datacenters."
""Project Rainier ... is now fully operational, less than one year after it was first announced," AWS said - and it's not stopping at that half-a-million Trainium2 chips, either. The cluster is already being used by Amazon's AI partners at Anthropic, who the company said will be scaling "to be on more than 1 million Trainium2 chips - for workloads including training and inference - by the end of the year.""
"From what we know based on earlier discussions with AWS staff in our preview of Project Rainier from the summer, each one of the datacenters housing the project will be massive. An AWS spokesperson told us in July that one site in Indiana that is now partially online as part of the Rainier cluster will eventually span 30 datacenter buildings, each measuring 200,000 square feet."
Project Rainier is fully operational less than one year after its initial announcement, deploying nearly half a million Trainium2 chips across multiple datacenters. Amazon plans to expand capacity, with Anthropic set to scale workloads to more than one million Trainium2 chips for training and inference by year-end. One Indiana site that is partially online will eventually span 30 datacenter buildings, each about 200,000 square feet. AWS described Rainier as one of the world's largest AI compute clusters but did not disclose the exact number of datacenters or the total compute power. Rainier competes with OpenAI-backed Stargate capacity.
