WebGPT

A fine-tuned GPT-3 model designed to navigate the web and provide sourced answers to complex questions.

WebGPT leverages a fine-tuned GPT-3 architecture to search the internet using a text-based browser, mimicking human research patterns to synthesize information. By citing specific sources from the live web, the system reduces factual hallucinations and provides verifiable evidence for its claims. OpenAI trained this model using imitation learning and reinforcement learning from human feedback (RLHF) to optimize for accuracy and information retrieval efficiency.
