Cerebras Systems announced the release of its third-generation 5nm wafer-scale engine (WSE-3), a chip designed specifically for training the industry's largest AI models. WSE-3's performance is twice that of its predecessor, WSE-2, while maintaining the same power consumption and price. Based on a 5nm process, it features 400 billion transistors and utilizes 900,000 AI-optimized compute cores to deliver 125 petaflops of peak AI performance.
