Cerebras Architecture Deep Dive: 10T Model Needs 50 Wafers
bookwormengr · x · 2026-08-19
Technical analysis of Cerebras: handling massive weights requires pipeline parallelism across multiple wafers. A 10T parameter model would need approx. 50 wafers (132GB each, holding 200B params at 4-bit, with remainder for KV cache). The author notes Cerebras' strength is decode over prefill and suggests a hybrid architecture: Attention on GPUs, FFN/Experts on Cerebras wafers.
