An American AI-silicon startup that makes the largest chips in the world—about the size of a dinner plate—from a single silicon wafer. Unlike Nvidia's graphics-processing units, Cerebras's chips are optimised for inference (running AI systems) rather than training them, giving them a speed advantage. The UAE's Mohamed bin Zayed University of Artificial Intelligence uses a data centre filled with Cerebras chips to run its K2 Think reasoning model, producing output at thousands of words per second.
Cerebras is on its third generation of chips. Its latest contains 900,000 cores and 44 gigabytes of on-chip SRAM. Because all data movement occurs within the wafer, Cerebras claims its system can run inference up to 15 times faster than conventional designs. For very large models, however, storing all parameters on SRAM remains impractical.
It's interesting to think that many quite distinguished people have bodies similar to yours.
