OpenAI makes free ChatGPT text chats unlimited

OpenAI will give ChatGPT Free and Go users unlimited GPT-5.6 Luna text chats starting next week, though separate limits remain for file uploads, images, and other tools. The company’s ChatGPT update also adds a Think button and says its internal factual-detail evaluation found responses with at least one error were 62% less common for Luna than for GPT-5.5 Instant. For builders tracking OpenAI’s push to turn ChatGPT into a super-app, the disappearing text cap raises the baseline for free assistants while leaving multimodal usage limits as the remaining upgrade lever.
