Cerebras Systems is an American computer hardware company founded in 2016 and headquartered in Sunnyvale, California that builds accelerators for artificial intelligence at wafer scale. Instead of assembling clusters from many small chips, it manufactures a single processor the size of an entire silicon wafer, the Wafer Scale Engine, which removes most of the communication overhead in large model training and inference. The company sells CS-series systems to research laboratories and enterprises, operates its own inference cloud known for very high token throughput, and has built large supercomputers with partners including the Gulf technology group G42.
