ChatGPT’s free tier is about to become considerably less restrictive for everyday conversations. OpenAI says Free and Go users will get unlimited text chats next week, removing the message cap that could previously interrupt a longer back-and-forth.
The change arrives alongside another model update: GPT-5.6 Luna will become the default ChatGPT model for Free and Go users this week.
- Free and Go users will receive unlimited text chats next week.
- GPT-5.6 Luna becomes the default model for those tiers this week.
- A new Think button will offer help with harder questions.
- Uploads, images, and other tools will continue to have their own limits.
Unlimited chats, with important limits still in place
“Unlimited” applies specifically to text conversations. Users will be able to keep asking questions and following up without running into the usual chat-message limit, although OpenAI says the feature remains subject to abuse guardrails.
That does not mean every ChatGPT feature becomes unlimited. File uploads, image creation, and other tools will still have separate usage limits, so heavy users may still encounter restrictions when working with documents or generating visuals.
A new default model for Free and Go
GPT-5.6 Luna will replace the current default model for ChatGPT Free and Go users. OpenAI has not positioned it as a paid-tier replacement, but pairing the new model with unlimited text chats should make the free experience feel much more useful for research, writing, planning, and everyday questions.
Free and Go users will also gain a Think button for tougher prompts. This should give people a simpler way to ask ChatGPT to spend more effort on a difficult question without needing to understand the differences between models.
What is not changing?
This update applies to ChatGPT itself. OpenAI says its Work and Codex experiences are not changing as part of this rollout.
GPT-5.6 Luna begins becoming the default for Free and Go users this week. Unlimited text chats and Think are scheduled to follow next week.
OpenAI announced the changes in its ChatGPT release notes.
