Free ChatGPT just became a much better deal. OpenAI is removing usage limits on text chats for free ChatGPT users, the company announced on Thursday. The change means free users can send unlimited text-only messages without hitting a daily cap. Goodbye to the wall I keep hitting right when a conversation gets interesting.
The company is also switching the default model for all users from GPT-5.5 Instant to GPT-5.6 Luna, the lightweight member of the GPT-5.6 family that launched in July after government review. Luna replaces the old instant model in the default slot, and it’s the cheap end of the family on purpose.
This is the free tier becoming a real product instead of a teaser. I’ve ranked every major AI subscription, and the pattern is obvious: the daily cap was the upsell. Kill the cap and the math changes for anyone who keeps hitting walls at lunchtime. For anyone on the fence about free ChatGPT versus a paid plan, the cap was the deciding factor.
Free ChatGPT text chats just went unlimited
Here’s the rollout in plain terms. GPT-5.6 Luna will become the default model for Free and Go users this week. Starting next week, they’ll also have unlimited text chats and access to a new Think button for harder questions (subject to abuse guardrails).
Limits will still apply for file uploads, images and other tools. Free users are getting the fast model, not the whole buffet.
For questions that require deeper reasoning, Free users can tap the new Think button to give GPT-5.6 Luna more time to work through the answer. Think of it as a manual override for the model’s effort dial. Same idea as the reasoning sliders on paid plans, but aimed at people who never see a pricing page.
The paid side gets something too. Plus and Pro users can access the updated version of GPT-5.6 Sol and the new slider in ChatGPT starting today. A new slider lets you choose how much thought ChatGPT puts into each response. Keep it quick for everyday questions, or move it up for planning, research, writing, coding, or decisions that need more thought. The tuned Sol that ships today is for the Chat experience only, and the version powering Work and Codex isn’t changing.
Why the free ChatGPT upgrade matters
The move is a retention play, and a smart one. Every week, 1 billion people turn to ChatGPT for everything from quick questions and web searches to planning, research, advice, and complex decisions.
ChatGPT crossed one billion monthly users in May, and removing limits for free users is a clear play to keep that base growing rather than losing them to Claude, Gemini, or the growing list of free alternatives.
The accuracy improvement is the headline number. OpenAI says Luna produces 62% fewer factual errors than Instant.
In an internal evaluation of financial, medical, and legal prompts requiring factual detail, responses containing at least one factual error were about 62% less common with GPT-5.6 Luna and 68% less common with GPT-5.6 Sol than with GPT-5.5 Instant. Those are the company’s own numbers, so treat them as a directional sign, not gospel.
I covered the price cuts for this model family last month, and the economics support the move. Free users and $8/month Go subscribers will also get a new Think button that gives the model more time to process harder questions. Plus and Pro subscribers ($20 and $200/month) get a slider tool on GPT-5.6 Sol, the heavyweight model, that lets them dial reasoning effort from high to extra high to pro depending on the task.
This is the part that matters for regular users. The free plan was always fine for a quick question or two. Now it’s a viable daily driver for text, and the Think button covers the questions that used to be paid-plan territory. I still wouldn’t call it a replacement for a paid subscription, but the gap just got a lot smaller.
The safety asterisk
There’s a serious side to removing the cap. Lawsuits against OpenAI have alleged that excessive chatbot use has harmed vulnerable users, including minors. Removing usage limits makes that exposure wider. OpenAI says it has added guardrails so models avoid romantic roleplay, age-restricted challenges, and presenting themselves as substitutes for real-world relationships for users under 18. Whether guardrails hold when the text spigot never turns off is a question the courts may answer.
Bottom line
Free ChatGPT is no longer the demo tier. It’s the funnel that keeps a massive base in the door, running a model that OpenAI says makes fewer mistakes than the one it replaces. If you’ve been limping along on the free plan, this is a real upgrade. Nothing here touches the stuff that makes power users pay: deep research, agent sessions, and the heavy models stay behind the paywall. That’s fine. CNET’s version of the story is worth a skim if you want the consumer view. The free ChatGPT experience just got meaningfully better, and the daily cap is finally gone.
