Cerebras Unveils CS-4 AI Accelerator With 30x GPU Speed For Inference Systems Cerebras Systems has launched the CS-4, a rack-scale AI accelerator powered by three wafer-scale WSE-3 Turbo processors with 4 trillion transistors. The company says the system can process up to 30 times more tokens per second per user than traditional GPU-based systems, with first shipments due this quarter.
The CS-4 is designed specifically for AI inference and uses SRAM rather than conventional dynamic RAM. The company links this to faster performance and a claimed 2x speed gain over its prior CS-3 system, positioning the new hardware as a direct challenger to incumbent GPU-focused architectures.
Cerebras Systems shares trade at US$209.85 and are down 32.5% year to date, which frames this hardware launch against a backdrop of recent share price pressure.
This launch raises the stakes in AI hardware, since meaningful speed and architecture differences can influence where large AI workloads are deployed and how capital-intensive those deployments become. Ankündigung • Aug 19
Cerebras Systems Unveils CS-4 AI Accelerator Cerebras Systems introduced the Cerebras CS-4, the fastest AI accelerator in the industry. The CS-4 is a rack-scale solution built from three new Wafer Scale Engines and revolutionary rack and system designs. The CS-4 is the first member of the next-generation Cerebras Nexus rack-scale platform architecture. It is up to twice as fast as the CS-3, bringing the CS-4s advantage in tokens-per-second-per-user over GPUs to up to 30x more. The CS-4 solution also delivers up to 10x more throughput per watt than the CS-3, vastly improving data center economics. The CS-4 delivers both higher-value tokens and more total tokens within a given power budget—enabling datacenters to be vastly more profitable. The rack scale CS-4 is built from three of the newly released Wafer Scale Engine 3 Turbo (WSE-3T). The CS-4 delivers 750 PFLOPs of AI compute, 7.2 terabits per second of I/O, and 129.6 petabytes per second of memory bandwidth. Total compute fabric bandwidth jumps to 160.5 petabytes per second, and wafer to wafer latency drops as low as two microseconds, enabling the creation of very large clusters and the support of models with over 50 trillion parameters. The CS-4 sets a new high watermark for inference speed. In a head-to-head comparison on GPT-OSS-120B, when given identical prompts, the CS-4 delivers more than 4,400 tokens second per user (TPS/user), up to 30 times faster than GPU solutions. CS-4 is powered by the newly announced WSE-3 Turbo (WSE-3T). Like the WSE-3, the WSE-3T is the largest AI processor ever built, containing four trillion transistors and 900,000 AI-optimized cores across 46,225 square millimeters of silicon, with 44GB of SRAM integrated directly on the wafer. The WSE-3T doubles AI compute to 250 PFLOPS per wafer and doubles memory bandwidth to 43.2 petabytes per second. The on-chip fabric bandwidth and off-chip I/O both double to 53.5 petabytes per second and 2.4 terabits per second respectively. I/O latency shrinks from five microseconds to as low as two microseconds. 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. Modularity enables each element to scale independently so innovations get to market faster. The modular architecture also supports extremely rapid deployment and upgrades. Cerebras has fundamentally re-imagined the compute subsystem into a rear mounted “backpack” that attaches vertically to the power array. Each Wafer-Scale Backpack is a self-contained assembly that folds power conversion, direct liquid cooling, high-speed I/O, and control electronics into a compact, three-dimensional package built directly around the wafer. By decoupling compute from the power supplies, the Wafer-Scale Backpack simplifies manufacturing and reduces deployment time from days to hours. Compared with the prior-generation system, the Wafer-Scale Backpack has 50% fewer components and uses 60% more automated manufacturing. The Nexus Platform Architecture drives significant power delivery improvements. By moving power conversion 100x closer to the processors – from roughly 50 millimeters away from the processor as on conventional GPU boards to approximately 0.5 millimeters – CS-4 nearly eliminates board-level power loss. This delivers twice as much power to the WSE-3T, enabling higher operating frequencies and faster token generation. CS-4 introduces a new programmable I/O subsystem that supports two connectivity modes while doubling I/O bandwidth and reducing latency. The fully programmable Wafer I/O Module supports standards-based RoCE v2 RDMA over Ethernet for seamless integration into existing infrastructure and with an ecosystem of heterogeneous systems. Aggregate off-wafer bandwidth doubles to 2.4 terabits per second per wafer and 7.2 terabits per CS-4 rack solution. The Wafer I/O Module also supports a new communication mode, called Direct Wafer Links, which enables wafers to be linked within and across racks without a switch. Direct Wafer Links enables wafer-to-wafer latency as low as two microseconds. This low latency communication will allow the creation of massive CS-4 clusters and the ability to support models with more than 50 trillion parameters. Programmable low latency I/O is particularly beneficial for heterogeneous disaggregated inference, in which a purpose-built prefill engine processes an incoming prompt and then hands it to Cerebras for ultra-low latency decode. The combination of programmability, standards-based interfaces, and very low latency will allow the rapid creation of disaggregated solutions from different Cerebras ecosystem partners, like AMD Helios and AWS Trainium. Metric comparison: CS-3 (one wafer) vs. CS-4 (3 wafers): AI compute: 125 PFLOPS vs. 750 PFLOPS; Memory bandwidth: 21.6 PByte/s vs. 129.6 PByte/s; On-chip fabric bandwidth: 26.7 PByte/s vs. 160.5 PByte/s; System I/O bandwidth: 1.2 Tbit/s vs. 7.2 Tbit/s; I/O latency: 5 microseconds vs. 2 microseconds. First CS-4 shipments begin this quarter. Full system specifications are available in the CS-4 datasheet. Major Estimate Revision • Aug 19

Cerebras Powers Ultrafast Mode For OpenAI’s GPT-5.6 Sol Cerebras powered OpenAI's most capable model at up to 14x the speed, giving frontier intelligence with no compromise on latency. Cerebras announced that it is powering Ultrafast mode, a new service tier in the OpenAI API for GPT-5.6 Sol. Available initially in limited preview to OpenAI customers, Ultrafast runs GPT-5.6 Sol at up to 750 output tokens per second and up to 14x faster than Standard processing. GPT-5.6 Sol Ultrafast powered by Cerebras runs with the same intelligence as GPT-5.6 Sol Standard, enabling frontier intelligence at Cerebras' blistering fast speed. Ultrafast powered by Cerebras offers access to the full intelligence of GPT-5.6 Sol at speeds suited to work that cannot wait. Based on output speeds for Anthropic models reported by Artificial Analysis, Ultrafast is 5x faster than Claude Opus 4.8 in Fast mode, and 11x faster than Claude Fable 5. Benchmarks focused on economically valuable work, from programming to drafting legal documents, show how faster token generation translates directly into higher productivity for users. On Humanity’s Last Exam, a 2,500-question benchmark spanning graduate-level chemistry, economics and literature, GPT-5.6 Sol Ultrafast answered the full question set in just over 11 hours. This compares to more than three days of continuous compute for Claude Fable 5, with GPT-5.6 Sol Ultrafast reaching comparable accuracy nearly 7x faster. On GDP-Val, a benchmark of economically valuable knowledge-work tasks such as legal briefs, financial models, and engineering reports, Ultrafast delivered a 5.6x end-to-end speedup with no loss in quality. Ultrafast’s speed comes from Cerebras' Wafer-Scale Engine architecture, which keeps model weights on-chip — 44 GB of SRAM on each wafer-sized chip — rather than shuttling them between on-chip memory and off-chip storage as GPU-based inference must. This eliminates the memory-bandwidth bottleneck that constrains frontier-model inference speed on conventional hardware. Reported Earnings • Aug 13
