OpenAI is finally killing ChatGPT’s text chat limits for free users

OpenAI has just announced that it’s now removing text chat usage limits for ChatGPT Free and Go accounts. Previously, Free and Go users were rate-limited to 10–40 text messages per 3–5 hours on flagship models, with users kicked down to a lighter model after hitting limits.

Along with this change, ChatGPT has now made GPT-5.6 Luna—the lightest model in its new GPT 5.6 family—the new default model for ChatGPT Free and Go users. It therefore replaces GPT-5.5 Instant, and it’s the one that now supports unlimited free chat messages with text. GPT-5.6 Luna is faster, more reliable, and more focused.

Note, however, that restrictions will still apply to messages that involve more resource-intensive features, including file uploads, image attachments, image generation requests, voice mode, and more.

OpenAI is also adding a new “Think” button that tells the model to take more time when formulating its response, resulting in deeper reasoning and better quality answers when needed.

The new changes will come into effect starting next week.
