What is the underlying technology behind ChatGPT?

ChatGPT is built on the GPT (Generative Pre-trained Transformer) architecture, specifically GPT-3.5. It utilizes a transformer neural network model that is pre-trained on a diverse range of internet text. This enables it to understand and generate human-like text based on the patterns and information it has learned during training. The transformer architecture allows for the model to process and generate sequences of text, making it effective for natural language understanding and generation tasks.
