What is ChatGPT?
ChatGPT by OpenAI is the most widely used AI assistant in the world. It runs on the GPT-5.6 family: Luna, the low-cost model that is the default for Free and Go users; Terra, the balanced option; and Sol, the flagship unlocked on Plus, with a higher-accuracy Sol Pro variant reserved for Pro and Enterprise. It handles conversation, writing, coding, data analysis, image generation and editing, web browsing, and file uploads, and it connects to sources like Google Drive so you can ask questions about your own documents.
Native apps cover macOS, Windows, iOS, and Android, with a Linux desktop app in preview, alongside ChatGPT Work for teams and Codex for coding. Free tier available; Go, Plus, Pro, Business, and Enterprise plans add higher limits and access to the stronger models.
