OpenAI announced today that it is removing limits on text-based chats for all ChatGPT users, including those on the free tier, as the platform surpasses 1 billion weekly active users. The change, which will be powered by the new GPT-5.6 Luna model, will become the default for Free and Go users, replacing GPT-5.5. This update is part of OpenAI’s broader effort to make its AI assistant more accessible and useful for everyday tasks.
What changes for Free and Go users
Starting this week, Free and Go users will see the new GPT-5.6 Luna model as the default for text conversations, eliminating previous caps on the number of text messages they can send. Additionally, a new “Think” button will be introduced next week, allowing users to opt for higher reasoning power on complex questions. OpenAI clarified that separate limits will still apply to files, images, voice, and image generation, so the unlimited text chat does not extend to all modalities.
Upgrades for Plus and Pro subscribers
Plus and Pro users are not left out. They will gain access to an upgraded GPT-5.6 Sol model, which OpenAI says is optimized for quick tasks such as answering questions, web research, advice, planning, writing, and decision-making. This version is distinct from the GPT-5.6 Sol used in Codex and Work, which remains unchanged. Subscribers will also receive a new “thinking slider” to adjust the depth of reasoning the model applies to a query, giving them finer control over response complexity.
Factual accuracy improvements
OpenAI shared internal evaluation results indicating that factual errors were 62% less common with GPT-5.6 Luna compared to GPT-5.5-Instant, and 68% less common with GPT-5.6 Sol. These improvements are part of the company’s ongoing focus on reliability, though independent verification is still pending.
Why this matters
This move signals a significant shift in OpenAI’s strategy to democratize access to advanced AI tools. By removing text chat limits, the company is likely aiming to attract and retain more users, especially as competition intensifies among AI chatbot providers. For everyday users, the change means more consistent access to a powerful assistant without worrying about hitting usage caps, potentially increasing reliance on AI for daily tasks.
Conclusion
OpenAI’s removal of text chat limits for free users, coupled with the introduction of GPT-5.6 Luna and the upgraded Sol model, represents a major step in making AI assistance more accessible. The rollout begins this week for Free and Go users, with the Think button arriving next week. As these changes take effect, users can expect a more seamless and capable ChatGPT experience.
