ChatGPT: Unlimited Text for Free Users Starts Next Week

OpenAI is removing rate limits for free and Go accounts on ChatGPT's pure text chats starting next week. This means users can have unlimited text conversations without a message cap. What's interesting is that GPT-5.6 Luna is also becoming the new default for these free accounts this week, replacing GPT-5.5 Instant. Free and Go users will also see a new "Think" button, allowing GPT-5.6 Luna more time for harder questions. This "Think" feature for pure text use also skips the rate limit. For paid Plus and Pro tiers, OpenAI is updating GPT-5.6 Sol, making answers more focused and matching detail to the question. These users will also get a new effort slider to control how much thought goes into each answer. The company claims stronger factual reliability with the new models, with factual errors reportedly falling significantly in internal checks. The bottom line is that removing message caps for text-only chats is a big change for how free users experience ChatGPT.
