OpenAI has announced that it is eliminating all limits on text-based chats for ChatGPT users, a move that comes just as the platform surpasses 1 billion weekly active users. The company shared the update in a blog post today, positioning this as a significant step toward making advanced AI assistance universally accessible.
What’s New for Free and Go Users
The new GPT-5.6 Luna model will power the free experience and will become the default for Free and Go users, replacing GPT-5.5. This model is designed to deliver high-quality responses without usage caps on text conversations, allowing users to engage in extended interactions without interruption.
In addition to unlimited text chats, Free and Go users will gain access to a new “Think” button, which enables them to invoke higher reasoning power for complex questions. OpenAI clarified that separate limits will still apply to files, images, voice interactions, and image generation—ensuring that multimodal features remain governed by existing constraints.
Enhancements for Plus and Pro Subscribers
For ChatGPT Plus and Pro users, the update introduces the upgraded GPT-5.6 Sol model, optimized for quick tasks such as answering questions, conducting web research, offering advice, planning, writing, and decision-making. According to OpenAI, this version delivers more compact and robust responses, improving efficiency for everyday use. Notably, this is a distinct variant from the GPT-5.6 Sol used in Codex and Work environments, which remains unchanged.
Plus and Pro subscribers will also receive a thinking slider, allowing them to adjust the amount of reasoning the model applies to a response. This granular control empowers users to balance speed and depth based on the complexity of their queries, from straightforward factual questions to multi-step problem-solving tasks.
Strategic Implications for 2026
This move reflects OpenAI’s broader strategy in 2026 to democratize access to cutting-edge AI while differentiating its paid tiers through advanced features rather than basic usage limits. By removing text chat caps, OpenAI aims to attract and retain a larger user base, particularly as competition intensifies in the generative AI space. The introduction of the “Think” button and thinking slider also signals a shift toward user-customizable reasoning, a trend that is likely to shape AI assistants throughout the year.
