ChatGPT Free: Unlimited Text Chats & GPT-5.6 Luna

OpenAI is removing usage limits on text-based conversations for free ChatGPT users. This means Free and Go users will soon have unlimited text chats. What's interesting is the default model for these users will be the new GPT-5.6 Luna, replacing the current GPT-5.5. Users will also get a new "Think" button to activate advanced reasoning for complex tasks. However, these unlimited chats only apply to text. Other features like file uploads, image and voice functions, and AI image generation will still have usage limits. For paid Plus and Pro subscribers, OpenAI is introducing the upgraded GPT-5.6 Sol model. This model offers improved performance for tasks like answering questions, web research, and writing. The company says it provides more concise and reliable responses. The bottom line is, many users will soon have more access to advanced AI for free text conversations.
