Additionally, free users will now have unlimited text chats, with no rate limits applying to text conversations.\n\nAn improved version of GPT-5.6, called GPT-5.6 Sol, is also being rolled out. According to 9to5Mac, ChatGPT is becoming more than just a chat platform over time.\n\nThe Verge reports that a \"Think\" button will be added for free and Go users, providing access to higher reasoning for more challenging questions. However, limitations will still apply to messages containing file uploads and images.",
