OpenAI is giving ChatGPT free users unlimited text chats

OpenAI is making changes to its ChatGPT service, specifically for users on the free and Go tiers. Starting next week, these users will have unlimited text chats with the chatbot, with no rate limits on text-based conversations. However, limits will still apply to messages that include file uploads and images.

In addition to the unlimited text chats, free and Go users will also gain access to a "Think" button. This feature allows users to access higher reasoning power for more complex questions. According to TechCrunch, the new GPT-5.6 Luna model will power this experience and will be the default model for Free and Go users, replacing GPT-5.5.

The changes also extend to Plus and Pro users, who will gain access to an upgraded GPT-5.6 Sol model. This model is designed for quick tasks such as questions, web research, advice, planning, writing, and making decisions, and is said to provide more compact and robust answers. An internal evaluation found that factual errors were 62% less common for GPT-5.6 Luna and 68% less common for GPT-5.6 Sol compared to GPT-5.5-Instant, as per TechCrunch.
