What Cerebras does
Cerebras Systems (NASDAQ: CBRS) builds wafer-scale AI compute infrastructure—hardware systems and the accompanying software and cloud services—centered on its Wafer Scale Engine (WSE) processor line and Cerebras CS systems (CS-2/CS-3 in on-prem or customer datacenters, with newer generations announced as CS-4). Cerebras positions its platform around ultra-fast AI inference and high-throughput training by using wafer-scale architecture intended to reduce interconnect and data-movement bottlenecks typical of multi-GPU clusters. The company sells and deploys AI systems for on-premise use and also provides pay-as-you-go cloud offerings, which are described as powered by the Wafer Scale Engine, while exposing developer tooling such as an inference SDK and training tooling. The business model therefore combines (1) hardware system deployments, (2) software/runtime tooling for model training and inference execution, and (3) Cerebras-hosted cloud capacity and usage-based inference services.
In 2026, Cerebras completed its IPO and became a public company, and it has continued expanding its infrastructure footprint (including European expansion plans), partnerships focused on disaggregated inference workflows, and tiered access to ultra-fast inference capacity for OpenAI API customers. Operationally, the company’s recent investor-relations releases emphasize scaling data center capacity, contracting megawatts, and growing revenue—particularly cloud—while reporting material financial metrics tied to its “core” business segment and performance-obligation backlog.
