Etched

Etched is an American semiconductor startup building Sohu, an application-specific integrated circuit (ASIC) designed to run only one thing: transformer models. By burning the transformer architecture directly into silicon, Etched claims an 8-chip Sohu server can match the throughput of 160 Nvidia H100 GPUs on Llama-70B inference. Founded in 2022 by three Harvard dropouts, the company has raised over $625M, including a recent $500M round at a reported $5B valuation.
