- Custom silicon collaboration. Anthropic uses AWS Trainium chips to build, train, and deploy its world-class AI models. Anthropic works closely with Annapurna Labs on developing and optimizing future Trainium chips, providing direct feedback from Claude training workloads to shape next-generation chip design for frontier AI models and benefitting other AWS customers. This has led to a strong engineering relationship that is helping Anthropic accelerate the development of their models with both engineering teams communicating on an almost daily basis on everything from low-level optimization work to high-level architectural decisions for next-generation chips.
- Project Rainier. AWS collaborated with Anthropic to launch Project Rainier, one of the world’s largest AI compute clusters with nearly half a million Trainium2 chips. When it launched, Project Rainier was larger than any AI compute cluster in the world and Anthropic is now actively using it to train and deploy Claude models for customers around the world for their AI-powered applications. Project Rainier is also being used to build and deploy future versions of Claude, and the more compute dedicated to training this frontier model, the smarter and more accurate it becomes. Project Rainier is now a template for deploying at scale the kind of raw computational power that will allow AI to tackle the hardest human challenges and enable breakthroughs across everything from medicine to climate science.
- Empowering builders worldwide. AWS is the best place to run Anthropic’s world-class family of Claude models, including Opus, Sonnet, and Haiku, and over 100,000 organizations of all sizes are running them on Amazon Bedrock to do things that weren’t previously possible. For example, Lyft incorporated Claude, via Amazon Bedrock, to power its customer care AI assistant, delivering fast responses to the most common support issues, and directing customers to a human specialist when more hands-on assistance is required, reducing average customer service resolution time by 87% and resolving thousands of customer requests daily. Pfizer is using Amazon Bedrock with Claude to help scientists search through the approximately 20,000 documents generated per drug development project using voice commands and a chatbot, saving scientists 16,000 annual search hours, while reducing infrastructure costs by 55%. Claude also powers experiences across a range of additional AWS technologies, including Amazon Connect, Kiro, and Amazon Quick, making it easy for developers to experiment, customize, and deploy AI on AWS.
- Primary training and cloud provider. Anthropic continues to choose AWS as its primary training and cloud provider for mission-critical workloads. Amazon developers and engineers also have access to build with Claude models to improve customer experiences across Amazon’s businesses.
