Diogo Almeida, founder, TypeSafeModels have been superhuman at chat for years, so where is all the automation?This has been my driving question for the last four years. At OpenAI, I helped build the methods that made language models useful at following instructions and talking with people. That work ended up as the research behind ChatGPT.
