01Summary

404 Media obtained internal documents about Project Lily. Contractors hired through intermediaries such as Crossing Hurdles and Mercor, reportedly paid more than US$50 an hour, review selected real user conversations. They score replies from 1 to 7, summarise user intent, and flag behaviours such as robotic phrasing or excessive agreement (sycophancy). OpenAI removes usernames and tries to redact personal data, but reviewers see whole threads and sensitive details still get through. ChatGPT has about 900 million active users. OpenAI also fired contractors caught using AI to do the grading.

02Key revelations

  1. 01People read full, real ChatGPT conversations to improve the model.
