## **The Fastest AI Just Got Faster\.**
Introducing the all new Cerebras CS\-4, a revolutionary rack\-scale solution that delivers up to 30x faster inference compared to GPUs, enhanced economics, and a simple path to deploy hyperscale capacity\. It is the architecture for frontier AI\.

### Three WSE\-3 Turbo per System
Each wafer delivers up to 2x the speed of the previous generation
### More Performance per Wafer
All new power, cooling, and I/O unleashes even more performance per wafer
### Nexus Rack\-Scale Platform
Enables rapid deployment in hyperscale datacenters
## Up to 30x faster than GPUs
Powered by WSE\-Turbo, CS\-4 delivers up to 30x faster inference compared to GPU systems, setting a new record for the fastest inference available in production\.
## Higher ultrafast throughput
The CS\-4 solution shifts the inference Pareto frontier, delivering up to 10x more throughput per watt than CS\-3 while generating tokens up to 30x faster than production GPU systems\. The result is a system designed to deliver both throughput and interactivity\.
## Frontier\-ready architecture
By reducing wafer\-to\-wafer interconnect latency to 2 microseconds, CS\-4 delivers more than 1,000 tokens per second on models exceeding 10 trillion parameters, preserving interactive decode performance at unprecedented scale\.
## BUILT FORHYPERSCALE
CS\-4 is the first iteration of the new Cerebras Nexus Platform Architecture\. It is built around a modular concept with three foundational elements: Compute, Power, and I/O – each with significant innovation to simplify manufacturing, deployment, maintenance, and upgrades\.

## Modular compute backpack design
Cerebras has fundamentally re\-imagined the server\. Each Wafer\-Scale Backpack is a self\-contained assembly thatfolds the wafer, power conversion, direct liquid cooling, high\-speed I/O, and control electronics into a compact 3D package with 50% fewer components\. This design simplifies manufacturing and reduces deployment time from days to hours\.
## High\-density power delivery
With power delivery just 0\.5 millimeters away from the processor \- roughly 100x closer than the roughly 50mm of conventional GPU boards \- CS\-4 nearly eliminates board\-level power loss\. This enables the delivery of twice as much power to the WSE\-3T, enabling higher operating frequencies and faster token generation\.
## Next\-gen wafer I/O interface
CS\-4 introduces a new programmable I/O subsystem that doubles I/O bandwidth and reduces latency, benefitting both aggregated and disaggregated solutions\. The Wafer I/O Module also enables wafers to be linked within and across racks without a switch, for wafer\-to\-wafer latency as low as two microseconds that is key to interactivity for models with tens of trillions of parameters\.
## Deploy infrastructure then compute
CS\-4 separates the stable power, cooling, and network layer from its modular wafer\-scale compute\. The Cerebras PowerRack can be installed and facility\-qualified before compute arrives\. Compute backpacks then slide into place and connect to power, cooling, and data—reducing deployment from days to hours while simplifying service and future upgrades at hyperscale\.
