The inside story of how ChatGPT was built – OpenAI cofounder John Schulman

This podcast episode explores the development of ChatGPT, a conversational chat assistant built on top of the GPT models. The project initially focused on instruction following models, but the team realized the significance of conversations in question answering and decided to build a conversational chat assistant. The development process involved fine-tuning the GPT-4 models, combining instruct and chat data sets, and using iterative supervised fine-tuning to create a model with a coherent personality and robust behavior.
