Cerebras
Wafer-scale AI chip delivering the fastest inference for LLMs. CS-3 system runs entire models on a single chip with no memory bottleneck.
What is Cerebras?
Cerebras Systems builds the world's largest computer chips, purpose-designed for AI. Their CS-3 wafer-scale engine (WSE-3) contains 4 trillion transistors on a single 8.5-inch wafer, eliminating the memory bottleneck that plagues GPU-based systems. Their inference API delivers 2,000+ tokens per second for large language models, making them the primary competitor to Groq in the speed race.
