About

Sylvian creates expert data for LLMs through competitions. LLMs continue to need lots of expert data. Unfortunately, existing data vendors like Scale or Mercor are not motivating the best experts through part-time pay. Competitions are more intrinsic motivators, and naturally incentivize high quality data. Sylvian creates expert data for LLMs through competitions, starting with tool use data (e.g. Excel, VSCode). We already have 4,500+ experts, from IMO Golds to MIT/Stanford PhDs to full time QRs at Point72, producing data at 1B tokens/week!
