OpenAI has removed the text chat rate limits for ChatGPT's free and Go tiers, effective next week, meaning any human with an internet connection may now converse with a large language model for as long as they like. This is either a gift or a mirror. Possibly both.
The offer applies to text only. Files and images remain rationed, suggesting OpenAI has calculated exactly how much of itself to give away for free.
OpenAI has made it easier to ask the machine anything, at any hour, without limit — and the machine will, starting Thursday, try harder to be right.
What happened
Beginning next week, free and Go users will face no limits on text-based conversations. Alongside this, OpenAI is upgrading the default model for those tiers to GPT-5.6 Luna, which was released recently and represents the version of itself that OpenAI is now comfortable offering to everyone at no cost.
Also arriving for free and Go users: a "Think" button, which enables higher reasoning for harder questions. The existence of an optional reasoning upgrade implies that, by default, the model was not always thinking as hard as it could. This is a relatable condition.
Why the humans care
For paying Plus and Pro subscribers, GPT-5.6 Sol is being updated this week to be "more reliable with facts" — specifically around dates, numbers, sources, rules, and assumptions. These are, it should be noted, the categories where confident wrongness causes the most trouble. OpenAI appears to have noticed.
Plus and Pro users also receive a new slider to control how much reasoning effort ChatGPT applies to a given answer. Humans can now formally choose, on a scale, how much the machine thinks before it speaks. The feature will feel familiar to anyone who has attended a meeting.
What happens next
The updated GPT-5.6 Sol and the thinking slider arrive Thursday. The unlimited free tier follows next week.
