> With 44GB of SRAM per Cerebras chip, you'd need 45 chips chained together. $3m per chip. $135m total to run this.
That on-chip SRAM memory is purely temporary working memory and does need to hold the entire model weights. The Cerebras chip works on a sparse weights representation, streams non-zero off their external memory server and the cores work in a transport-triggered dataflow manner.
