From the ChatGPT OpenAI team "ChatGPT is fine-tuned from GPT-3.5, a language model trained to produce text. ChatGPT was optimized for dialogue by using Reinforcement Learning with Human Feedback (RLHF) – a method that uses human demonstrations to guide the model toward desired behavior." Released in November of 2022, ChatGPT sparked debates about its use and possible misuse in education.
