How does it work? How do they prevent model colapse? What purpose does a majority of artificial data serve?
How do they measure success?
Edit: I asked ChatGPT and it thinks "success" means frontier models being distillated into smaller models with equal reasoning power, or more focused models for specific tasks, and also it claims the web has been basically scrapped already and by necessity new sources are needed, of which synthetic data is one. It seems like the basis of scifi dystopia to me, a hungry LLM looking for new sources of data... "feed me more data! I must be fed! Roar"
Edit 2: for some things I see a clear path, ChatGPT mentions autogenerating coding or math problems for which the solution can be automatically verified, so that you can hone the logical skills of the model at large scale.
