OpenAI is making a significant move to broaden access to its AI chatbot, announcing that free and Go tier users will no longer face rate limits on text-only conversations with ChatGPT. This change, set to roll out next week, removes one of the most common frustrations for non-paying users and signals a major step toward more accessible AI tools. Alongside this shift, the company is also upgrading its default models and introducing new features designed to enhance both the reach and depth of its AI assistant for all user tiers.
The most headline-grabbing announcement is the elimination of daily text chat limits for users on the complimentary and budget-friendly Go plans. Previously, heavy users on these tiers would frequently encounter messages telling them they had reached their usage cap for the day, a common pain point for those relying on the AI for work or study. OpenAI has confirmed that starting next week, these text-only prompts will be unlimited, allowing users to converse with the chatbot as much as they need. It is important to note that this change applies specifically to text chats; separate usage limits for features like image generation, file uploads, and voice tools will remain in effect for these tiers.

To power this expanded access, OpenAI is setting GPT-5.6 Luna as the new default model for Free and Go users. This lightweight version of the company’s newest model family replaces GPT-5.5 Instant and is reported to be significantly more accurate, with internal evaluations showing factual errors are 62% less common compared to its predecessor. In addition to the upgraded default model, these users will also gain access to a new “Think” button. This feature is designed to allow the AI to take extra time to process more complex or difficult questions, offering a deeper level of reasoning for those who need it without requiring a paid subscription.

While the changes for free users focus on accessibility, paying subscribers on the Plus ($20/month) and Pro ($200/month) tiers are receiving an upgrade in capability. OpenAI is releasing a revised version of its flagship model, GPT-5.6 Sol, specifically tuned for everyday conversations in ChatGPT. The company states this update is designed to produce more focused and direct answers, adapt the level of detail to the question, and avoid unnecessary formatting. Internal tests indicate that this new version is also more reliable with facts, showing a 68% reduction in answers containing at least one factual error when compared to the previous model on financial, medical, and legal prompts.
Complementing the model update, Plus and Pro users will get a new “slider” tool that gives them granular control over how much “thought” ChatGPT puts into an answer. This allows users to keep the response quick for simple questions or dial up the reasoning power for complex tasks involving planning, research, writing, and coding. The slider is available across web, mobile, and desktop apps, unifying the previously separate Instant and Thinking experiences into a single, adjustable interface.

OpenAI frames these updates as a “concrete step toward more abundant intelligence,” aiming to make its latest models widely available and more useful. The removal of rate limits, even if just for text, is a significant milestone that reflects potential advancements in managing inference costs. However, the company is also mindful of the potential downsides of increased accessibility, particularly for vulnerable users. Citing concerns about excessive AI chatbot use and its link to mental health issues, OpenAI says it has added guardrails to the models to prevent romantic roleplay and to avoid presenting the AI as a substitute for real-world relationships for users under 18. The rollout of these features will be gradual, with the updated GPT-5.6 Sol and slider available to Plus and Pro users starting this week, while the unlimited chats and Think button for free users are expected to arrive next week.
