I'm Peiyuan Liao, a computer systems engineer and founding member of technical staff at Prometheus. Recently, I trained the computer use model at General Agents before we were acquired.

I believe technology should foster human agency, not smother it.

On a less serious note, I think computers are cool and if you squint closely enough, many of the interesting problems about computers are either a pipeline, a tile, or a fault.

I'm building pretraining systems for our frontier models. I also consult for Condé Nast, helping out with AI strategy and engineering execution.
