Rumor: New Architectures Could Cut Cerebras K3 Wafer Needs From 60 to 10

bookwormengr · x · 2026-10-23

Quoting Joe Fioti's "60+ wafers per replica" remark, an unverified analysis argues K3's 2.8T parameters and 1.5TB storage justify Cerebras' 60-wafer count, but new architectures could cut it to 10 wafers at hardware cost near a single NVL72. Mythos-class cyber models like GLM 5.3 and DeepSeek v4.1 flash (800B) need only 500B weights on-wafer (embeddings off-chip), and DS-style prefill using half the layers would let Cerebras handle prefill and large-micro-batch decode efficiently. Speculative, unconfirmed.
