AWS, Amazon's cloud division, is the largest cloud provider globally and the primary driver of Amazon's operating profits. Amazon has increasingly positioned AI as central to its cloud strategy, investing heavily in custom silicon, foundation models, and AI-powered services across its product portfolio.

Amazon AWS designs AI training chips (Trainium) and inference chips (Inferentia), deployed within its cloud infrastructure and accessed through Amazon Bedrock alongside third-party models. AWS also develops its own foundation models (Amazon Nova) and operates Bedrock as a managed AI platform aggregating models from multiple providers.

In March 2026, AWS announced a multi-year partnership with Cerebras Systems deploying a "disaggregated inference" architecture: Trainium handles the prefill stage while Cerebras' wafer-scale CS-3 chip handles token decoding, available through Amazon Bedrock. AWS is the first cloud provider to offer this architecture commercially.
