ChatGPT is OpenAI's chat product layered on top of their GPT model family. Free tier runs on GPT-4o mini; Plus ($20/mo) gives access to GPT-5, Advanced Voice mode, DALL-E 3 image generation, and Code Interpreter; Pro ($200/mo) unlocks o-series reasoning and Sora video. ChatGPT memory persists across conversations, voice mode handles fluent dialog, and the recently expanded tool ecosystem includes web search, file analysis, custom GPTs, and connectors. By 2026 it's still the default AI tool for non-technical users despite Claude's writing-quality edge and Gemini's context-window advantage.
