    "excerpt": "SUNNYVALE, Calif., Aug. 18, 2026 (GLOBE NEWSWIRE) -- Cerebras Systems (NASDAQ: CBRS) today 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. Because fast tokens are more valuable than slow tokens, the CS-4 delivers both higher-value tokens and more total tokens within a given power budget - enabling datacenters to be vastly more profitable. “In AI, speed is productivity,” said Andrew Feldman, CEO and co-founder of Cerebras. “Historically, fast inference meant using smaller and less capable models. Cerebras CS-4 delivers industry-leading speeds on the largest frontier models, fundamentally changing the paradigm. Every aspect of the design has been optimized to deliver the highest speeds with massive throughput. With the CS-4, AI is so fast that it fundamentally reshapes product experiences.” The rack scale CS-4 is built from three of the newly released Wafer Scale Engine 3 Turbo (WSE-3T). The...",
