Cerebras

Cerebras operates wafer-scale supercomputer clusters delivering 450+ tokens/second for LLM inference. Their CS-3 system uses a single wafer-scale chip (WSE-3) with 44GB of on-chip SRAM per core, providing extreme throughput for large model serving. Cerebras hosts Llama 3.3 70B and other open-weight models with verified developer tiers.

Why Choose Cerebras?

Cerebras WSE-3 places 4 trillion transistors on a single 46,225mm² wafer, eliminating the chip-to-chip interconnect bottleneck. Each core has 44GB of SRAM with 20 petaflops of compute, enabling inference without the memory wall entirely. Their Cerebras Inference API uses a compiler that maps transformer attention directly to the wafer's mesh topology, achieving deterministic latency of under 20ms per token. The system eliminates GPU kernel launch overhead entirely through full-stack compilation.
