Anthropic and Amazon announced a significant expansion of their partnership to secure up to 5 gigawatts (GW) of capacity to train and run Claude. Why does that sound like a lot? Because behind that number are big investments, large-scale chips, and a bet on keeping things fast and reliable as demand grows.
What was announced
The collaboration between Anthropic and Amazon deepens with an agreement that guarantees up to 5 GW of new capacity to train and run Claude. The plan includes the arrival of Trainium2 in the first half of the year and almost 1 GW total of Trainium2 and Trainium3 before the end of 2026.
Anthropic has already been working with Amazon since 2023: more than 100,000 customers use Claude on Amazon Bedrock, and together they launched Project Rainier, one of the largest compute clusters in the world.
Why it matters
Have you ever wondered why an AI model’s responses slow down or become unreliable during peak times? It’s all about infrastructure. Training giant models and serving millions of users at once requires enormous resources.
