OpenAI is giving ChatGPT free users unlimited text chats

OpenAI is removing text chat rate limits for free and Go tier users while introducing a new 'Think' button for advanced reasoning. Additionally, the company is upgrading its default AI models and providing Plus/Pro subscribers with a new slider to control the depth of the model's reasoning.
Why it matters
This update significantly lowers the barrier to entry for advanced AI tools, potentially shifting user expectations for free-tier chatbot capabilities.
OpenAI is making a big change for ChatGPT users on its free and Go tiers: starting next week, users on those tiers will be able to have unlimited text chats with the chatbot, according to OpenAI. Right now, you may run into rate limits if you do too many text chats on those tiers, but those limits, just for text, will be going away soon. Messages that include things like file uploads and images will continue to have limits.
Next week, OpenAI is also adding a “Think” button for free and Go users that they can use to “access higher reasoning for harder questions.” This week, for those users, the company is additionally upgrading ChatGPT’s default AI model to the recently-released GPT-5.6 Luna.
