OpenAI is changing how far people can go with ChatGPT on its free and Go tiers. Starting next week, users on those plans will be able to keep sending text-only chats without hitting the text chat rate limits that can apply today.
The change is narrow but important: it applies to text chats. Messages that involve file uploads, images, or similar inputs will continue to have limits.
What Changes For Free And Go Users
The biggest update is the removal of text chat limits for ChatGPT users on free and Go tiers. At the moment, people on those tiers may encounter rate limits after doing too many text chats. OpenAI says those text-only limits are going away soon.
That makes the core ChatGPT experience more open for users who mainly type questions, drafts, summaries, explanations, or follow-up prompts. It does not mean every kind of ChatGPT message becomes unlimited. The distinction matters because OpenAI is keeping limits in place for messages that include things like file uploads and images.
For many users, the practical takeaway is simple: regular written conversations with ChatGPT should become less constrained on the free and Go tiers. More complex interactions that use extra inputs will still be managed separately.
The New Think Button
OpenAI is also adding a “Think” button for free and Go users next week. The company says the button will let those users “access higher reasoning for harder questions.”
That positions the button as a way to ask ChatGPT to spend more effort on questions where a quick answer may not be enough. The source does not describe every detail of how the button works, but the stated purpose is clear: harder questions can be routed toward higher reasoning.
This is separate from the unlimited text chat change. Together, the updates make the free and Go tiers more flexible for ordinary text use while giving users a visible control for questions that may need deeper reasoning.
GPT-5.6 Luna Becomes The Default
OpenAI is also upgrading the default AI model for free and Go users this week. Those users are being moved to the recently-released GPT-5.6 Luna as the default model in ChatGPT.
That means the free and Go updates are not only about quantity. OpenAI is also changing the model that users start with by default. The source does not provide additional performance claims for GPT-5.6 Luna, so the core fact is the model switch itself.
Seen together, the changes create a clearer split in the product experience. Free and Go users get unlimited text chats, a new Think button, and GPT-5.6 Luna as the default. Plus and Pro subscribers get a different set of upgrades focused on GPT-5.6 Sol and answer control.
What Plus And Pro Users Get
For Plus and Pro subscribers, OpenAI is updating GPT-5.6 Sol in ChatGPT. OpenAI says the model will be “more reliable with facts.”
The company describes the change as an effort to reduce mistakes in answers that depend on sensitive details. In OpenAI’s words, “The new GPT‑5.6 Sol is designed to make fewer mistakes — especially when answers depend on dates, numbers, sources, rules, or assumptions — by better using the sources it finds to answer your question.”
That description points to a focus on factual reliability in situations where small details can change the quality of an answer. Dates, numbers, sources, rules, and assumptions are all areas where a response can look fluent while still being wrong. OpenAI’s stated goal is for the updated GPT-5.6 Sol to use found sources better when answering.
OpenAI also says the updated GPT-5.6 Sol will provide “more direct responses” with “tighter formatting.” The company adds that ChatGPT will “avoid extra detail when it does not help.”
That is a notable product direction because it addresses not only factual accuracy, but also presentation. The update is described as making answers more direct, more tightly formatted, and less padded when extra context is not useful.
A Slider For How Much Thought ChatGPT Uses
Plus and Pro subscribers are also getting a new slider. OpenAI says the control lets users decide “how much thought ChatGPT puts into an answer.”
The updated GPT-5.6 Sol and the slider will both be available starting Thursday. That gives paid subscribers two linked changes: a model update aimed at stronger factual reliability and a control for adjusting how much reasoning effort ChatGPT applies.
The overall update gives each tier a different emphasis. Free and Go users get broader access to text chats and a Think button for harder questions. Plus and Pro users get an updated GPT-5.6 Sol, more direct answers, tighter formatting, and a slider for answer effort.
The limits that remain are just as important as the limits going away. Unlimited access applies to text chats on free and Go tiers. Messages with file uploads and images will still have limits, so users should not treat this as unlimited access to every ChatGPT feature.
