# ChatGPT

> OpenAI's ChatGPT runs on GPT-5.5 with deep research, agent mode, and Sora video — free tier plus paid plans from $8/month (Go) to $200/month (Pro).

ChatGPT is OpenAI's flagship AI assistant platform, now powered by GPT-5.5 — the current model after the GPT-5.2 family was retired in June 2026. It helps with writing, code, research, analysis, brainstorming, and more, supporting text, images, and file uploads. Paid plans from Go ($8/month) to Pro ($200/month) unlock deep multi-source research, agent mode for autonomous multi-step tasks in a virtual environment, Sora video generation, the Codex coding agent for end-to-end software work, advanced reasoning ("Thinking") models, and real-time Advanced Voice Mode. With over 400 million weekly users, ChatGPT is the world's most widely used AI product and the benchmark against which all AI assistants are measured.
