OpenAI removes limits on free ChatGPT text chats, launching GPT‑5.6 Luna as the default model and adding a new “Think” button for complex queries.
OpenAI has lifted the long‑standing cap on free‑tier ChatGPT text conversations, allowing users to chat without hitting a daily limit.
Unlimited chats for free accounts
Effective immediately, the free tier will no longer truncate sessions after a set number of messages, a move aimed at boosting accessibility and encouraging broader adoption of the platform.
The change coincides with the rollout of the new GPT‑5.6 Luna model, which is now the default engine for all free‑user interactions.
Introducing GPT‑5.6 Luna
GPT‑5.6 Luna builds on the capabilities of its predecessor, offering improved contextual awareness, faster response times, and a more nuanced grasp of complex topics.
OpenAI describes Luna as a "lightweight" yet powerful model, optimized for the high‑volume demands of free users while still delivering the quality expected from the brand’s premium offerings.
The new “Think” button
Alongside unlimited chats, OpenAI has added a "Think" button that users can press to signal that a query requires deeper reasoning or multi‑step analysis.
When activated, the button prompts the model to allocate additional compute resources, resulting in more thorough answers for intricate prompts such as legal reasoning, scientific explanations, or multi‑part problem solving.
- No daily message cap for free users
- Default model switched to GPT‑5.6 Luna
- Optional “Think” mode for complex queries
OpenAI says the enhancements are part of a broader strategy to democratize AI access while gathering more usage data to refine future model iterations.
We want everyone to experience the full potential of conversational AI without barriers, and Luna combined with the Think button brings us closer to that vision.
The unlimited chat feature is expected to roll out globally within the next 24 hours, with existing free‑tier accounts automatically receiving the update.
