TL;DR

  • The most economically significant AI self-improvement mechanism is the post-training pipeline.
  • This pipeline involves a loop where a model generates answers, these answers are graded, and the good ones are used as training data.
  • The model then trains on this data, improving its ability to produce better answers.
  • This process, known by terms like STaR or RLVR, is responsible for the evolution of frontier models into agents.
  • This loop is already being operated at an industrial scale by major AI labs.
