ChatGPT

What is ChatGPT?

ChatGPT is OpenAI's general-purpose AI assistant. You type or speak a request and it writes, explains, plans, summarizes, searches the web, reads uploaded files and images, and generates pictures. Paid plans add stronger GPT-6 reasoning models, larger limits for uploads and memory, deep research that compiles sourced reports, projects, scheduled tasks and custom GPTs. Codex handles coding work, and ChatGPT Work takes actions across your apps and files. People use it for studying, drafting emails and essays, debugging code, market research and everyday questions. It is available on the web and in mobile apps. The ChatGPT pricing page lists four individual plans, Free, Go, Plus and Pro, but the text we reviewed does not show dollar amounts, so confirm current prices on chatgpt.com before upgrading.
