Cerebras Systems and Amazon partner to integrate AI hardware with Trainium 3 in AWS data centers

Cerebras Systems and Amazon have announced a partnership to provide semiconductor solutions for a new AI service. Cerebras chips will be installed in AWS data centers and integrated with Amazon's Trainium 3 AI processors using Amazon's proprietary custom networking technology.
Context
In a landmark cloud infrastructure deal, Amazon Web Services (AWS) and chip startup Cerebras Systems have announced a strategic partnership to deploy the Cerebras CS-3 system within AWS data centers. This collaboration introduces a unique "disaggregated inference" architecture, where Amazon’s custom Trainium3 chips handle the initial "prefill" phase of AI requests while Cerebras’s wafer-scale hardware manages the high-bandwidth "decode" phase. The integrated system, connected via Amazon's high-speed Elastic Fabric Adapter (EFA) networking, is expected to launch on Amazon Bedrock within the next few months.
This partnership marks the first time a major cloud provider has integrated Cerebras's specialized hardware, aiming to deliver a 5x boost in high-speed token capacity compared to existing GPU-based solutions. The move directly challenges Nvidia's dominance by offering a high-performance alternative for compute-intensive tasks like agentic coding and real-time reasoning. For AWS, the deal secures critical infrastructure to support massive demand from partners like OpenAI, which recently committed to consuming 2 gigawatts of Trainium capacity to power its next-generation AI models.
