Wafer-Scale Engine (WSE)
A revolutionary chip architecture developed by Cerebras Systems where an entire 300mm silicon wafer is used as a single processor, rather than being cut into hundreds of smaller chips. The WSE-3 (third generation, released 2024) contains 4 trillion transistors and 900,000 AI-optimized compute cores — making it the largest chip ever built. Unlike traditional GPU clusters that require data to move between separate chips via network interconnects, the WSE keeps everything on-die with 44GB of on-chip SRAM, eliminating memory bottlenecks. This enables significantly faster AI inference for models like GPT-5.3-Codex-Spark. OpenAI partnered with Cerebras on a 750MW facility to leverage this technology for high-speed coding model inference.
