Cerebras CS-4: 30× From the Same Silicon
Cerebras unveiled the CS-4 on August 18 without changing its WSE-3 wafer at all — the gains come from moving power conversion 100× closer to the die and adding a third wafer per rack. The result is a system claiming 4,400 tokens/sec/user, a number that is hard for GPU clusters to match at low batch sizes, along with a 125–135 kW rack TDP that represents the real engineering bet.
