OpenAI has announced a major expansion of ChatGPT’s free tier by removing limits on text-based conversations for Free and Go users. Starting next week, users on these plans will be able to engage in unlimited text chats, eliminating one of the platform’s longest-standing restrictions. The update is accompanied by the rollout of OpenAI’s new default model, GPT-5.6 Luna, and a new “Think” button for handling more complex queries. Together, the changes significantly narrow the gap between free and paid ChatGPT experiences while preserving premium features for Plus and Pro subscribers.
The announcement comes as competition in the AI chatbot market intensifies, with rivals including Google, Anthropic, Meta, and open-weight AI models offering increasingly capable services. Rather than restricting everyday conversations, OpenAI is shifting its monetization strategy toward advanced capabilities such as higher multimodal limits, premium reasoning models, and professional productivity features.
OpenAI Removes Text Chat Limits for Free Users
Beginning next week:
- Free and ChatGPT Go users will receive unlimited text conversations.
- The previous cap on text prompts will be removed.
- Limits on image generation, file uploads, and other compute-intensive features will remain.
- The update will roll out gradually across eligible users.
Feature Rollout
| Feature | Free | Go | Plus | Pro |
|---|---|---|---|---|
| Unlimited text chats | ✅ | ✅ | ✅ | ✅ |
| GPT-5.6 Luna | ✅ | ✅ | Available | Available |
| Think button | ✅ | ✅ | Included | Included |
| Thinking slider | ❌ | ❌ | ✅ | ✅ |
| Higher image/file limits | Limited | Higher than Free | Higher | Highest |
GPT-5.6 Luna Becomes the Default Model
OpenAI is also replacing the default chatbot model for Free and Go users with GPT-5.6 Luna.
According to the company, Luna offers:
- Better reasoning quality.
- Improved writing capabilities.
- Stronger factual accuracy.
- Faster everyday performance.
Internal evaluations cited by OpenAI indicate that GPT-5.6 Luna produces 62% fewer factual errors than GPT-5.5 Instant, while GPT-5.6 Sol, the premium model for Plus and Pro users, reduces factual errors by 68%.
Model Comparison
| Model | Primary Users | Focus |
|---|---|---|
| GPT-5.6 Luna | Free and Go | Everyday conversations, writing, reasoning |
| GPT-5.6 Sol | Plus and Pro | Higher accuracy and advanced reasoning |
New “Think” Button for Harder Questions
Another addition for Free and Go users is the Think button.
The feature allows users to request additional reasoning time for questions involving:
- Multi-step logic.
- Planning.
- Mathematics.
- Coding.
- More complex analytical tasks.
Rather than answering immediately, ChatGPT can spend additional compute on producing a more carefully reasoned response.
Plus and Pro Users Get More Control
Paid subscribers also receive new capabilities.
OpenAI is introducing a Thinking Slider, allowing users to choose how much reasoning effort ChatGPT applies before responding.
Users can adjust responses depending on whether they prioritize:
- Faster answers.
- More detailed reasoning.
- Higher accuracy.
- Better planning for complex tasks.
The updated GPT-5.6 Sol model is also rolling out immediately for Plus and Pro subscribers.
Why This Matters
Removing text message limits marks one of the biggest upgrades ever made to ChatGPT’s free tier.
The change reflects several broader industry trends:
- AI chatbots are becoming everyday productivity tools.
- Competition among AI providers is increasing.
- Companies are differentiating paid plans through premium capabilities instead of basic access.
- Advanced multimodal features remain the primary incentive for subscriptions.
By making unlimited conversations available to everyone, OpenAI is lowering the barrier to everyday AI adoption while reserving higher-end reasoning, multimodal capabilities, and enterprise tools for paying customers.
Looking Ahead
OpenAI’s decision to introduce unlimited text chats for Free and Go users represents a significant shift in the company’s product strategy. Instead of limiting everyday conversations, ChatGPT’s free experience is becoming substantially more capable with GPT-5.6 Luna, unlimited messaging, and the new Think button. These improvements are designed to make AI assistance more accessible while enabling users to tackle a broader range of personal, educational, and professional tasks without hitting text message caps.
Looking ahead, the move is likely to intensify competition across the AI industry as providers increasingly compete on model quality, multimodal capabilities, and user experience rather than basic access limits. Paid plans such as Plus and Pro will continue to differentiate themselves through more advanced reasoning models, greater usage allowances, and enhanced productivity features, while the free tier evolves into a far more capable everyday AI assistant.
