OpenAI removes text-chat rate limits for free users, rolls out GPT-5.6 Luna by default
Starting next week, ChatGPT free and Go tier users get unlimited text conversations and access to a new Think button for complex reasoning.

OpenAI is removing a long-standing friction point for free-tier users: next week, ChatGPT’s free and Go tiers will support unlimited text conversations, eliminating rate limits that previously throttled heavy users. Paid subscribers—Plus and Pro tier members—gain access to an updated GPT-5.6 Sol model with factuality improvements and a new reasoning-intensity control slider, rolling out as early as Thursday.
Unlimited Text Chats and GPT-5.6 Luna for Free Users
According to The Verge, OpenAI is lifting text-chat rate limits for free and Go tier users starting next week. The change applies to text-only conversations; multimodal requests involving image uploads or file attachments will continue to face constraints. The company is simultaneously upgrading ChatGPT’s default model on these tiers to GPT-5.6 Luna, the recently released variant. Free and Go users will also gain access to a new “Think” button, enabling higher reasoning capabilities for complex questions.
This move signals OpenAI’s strategy to deepen engagement among its non-paying user base before converting them to paid tiers. Removing text-rate limits lowers the barrier to extended, multi-turn conversations—the primary use case for free-tier adoption.
GPT-5.6 Sol Factuality Improvements and Reasoning Control for Paid Tiers
Plus and Pro subscribers receive GPT-5.6 Sol, an updated variant designed to reduce factual errors, particularly when answers depend on dates, numbers, sources, rules, or logical assumptions, according to The Verge. The model now references its sources more rigorously during generation. Paired with formatting optimizations that make responses more direct and concise, GPT-5.6 Sol omits superfluous detail when it does not advance the answer.
Paid users also gain a new slider control that lets them adjust how intensively ChatGPT reasons through a question—a feature that bridges the gap between fast, surface-level responses and methodical, step-by-step deliberation. Both GPT-5.6 Sol and the reasoning slider launch on Thursday.
Why This Matters
The unlimited text-chat policy targets a critical conversion funnel: free users with high engagement (frequent, multi-turn conversations) often graduate to paid plans when they hit rate limits. By removing that barrier, OpenAI may increase stickiness among power users who would otherwise seek alternatives. For knowledge workers and professionals evaluating ChatGPT as a research or writing tool, the factuality improvements in GPT-5.6 Sol and the reasoning slider offer measurable control over output quality—addressing a long-standing complaint that LLMs hallucinate or over-explain. The dual-track rollout (free-tier speed, paid-tier accuracy) reinforces OpenAI’s tiered differentiation strategy without sacrificing free-user retention.
Frequently Asked Questions
Will image and file uploads still have limits on free tiers?
Yes. According to The Verge, only text conversations become unlimited; multimodal inputs (images, file uploads) retain rate limits.
What is the Think button, and when does it launch?
The Think button allows free and Go users to access higher reasoning for harder questions. According to The Verge, it rolls out next week alongside the unlimited text-chat change.
What changes are coming to GPT-5.6 Sol for paid users?
GPT-5.6 Sol is being updated to reduce factual errors, provide more direct responses with tighter formatting, and includes a new slider letting users control reasoning intensity.
