ChatGPT

ChatGPT is an AI-powered conversational assistant from OpenAI that exposes the company’s large language models through a chat interface. It supports text, images, and voice and can browse the web to surface current information with citations.

ChatGPT can generate, explain, and refactor code, assist with debugging, and run file-based analyses to create charts and summarize datasets. It also supports custom GPTs to tailor behavior for specific tasks and offers connectors to popular document and code sources for organization-wide search and “deep research”.
