Open AI trained GPT 3 .5 model ( pre trained set of Transformers) and crafted Chat GPT using Reinforcement Learning from Human Feedback (RLHF) And supervised fine-tuning.
To create a reward model for reinforcement learning, Open AI team during training randomly selected. model-written message, sampled several alternative completions, and had Human AI trainers rank them. Using these reward models, Open AI fine-tune the model using Proximal Policy Optimization. Open AI performed several iterations of this process.
