AWS and Cerebras Forge Alliance to Deliver Industry’s Fastest AI Inference via Disaggregated Architecture

24 MARCH 2026·8 MIN READ·8 SOURCES

Amazon Web Services (AWS) and Cerebras Systems have teamed up to launch a groundbreaking AI inference solution that divorces the inference process into two specialized workloads. By combining AWS Trainium3 accelerators for prompt processing with Cerebras’s CS-3 wafer-scale engine for token generation, accessible through Amazon Bedrock, this partnership challenges the dominance of traditional GPU inference setups, promising unprecedented speed and efficiency.

AWS and Cerebras Forge Alliance to Deliver Industry’s Fastest AI Inference via Disaggregated Architecture

Key takeaways · 5

  • 01

    AWS and Cerebras introduce a disaggregated AI inference solution splitting the process into prefill (prompt processing) and decode (token generation) stages.

  • 02

    Prefill workloads run on AWS Trainium3 accelerators optimized for parallel processing and large memory capacity.

  • 03

    Decode workloads are handled by Cerebras CS-3 wafer-scale engines providing massive memory bandwidth for latency-sensitive token-by-token generation.

  • 04

    The two-stage system is connected via AWS Nitro Elastic Fabric Adapter network to maximize performance.

  • 05

    This architecture delivers up to 5x improvement in token throughput and significantly reduces inference latency over traditional GPU-based systems.

The partnership between AWS and Cerebras marks a significant milestone in AI infrastructure evolution, addressing the critical bottleneck of AI inference by specializing hardware according to workload characteristics. By delivering the fastest inference solution through a novel disaggregated architecture, this collaboration not only directly challenges the prevailing GPU dominance, notably NVIDIA's, but also democratizes access to cutting-edge inference speed and efficiency via the AWS cloud. This advance promises to enable scalable, cost-effective deployment of real-time AI services, empowering enterprises and developers to meet rising demands from increasingly sophisticated generative AI applications.
