Amazon and Anthropic are building a monster AI supercomputer
Amazon is teaming up with Anthropic to build Project Rainer, a massive AI supercomputer powered by hundreds of thousands of its custom Trainium 2 chips. AWS says the system is 30% to 40% cheaper than Nvidia setups and five times larger than Anthropic’s current training cluster. Why it matters: Amazon is proving Nvidia isn't the only viable game in town, giving frontier AI builders a much cheaper route to compute.
