ChatGPT Free: Unlimited Conversations & GPT-5.6 Luna Rollout

OpenAI is rolling out unlimited text conversations for ChatGPT Free and ChatGPT Go users. This update removes a major limitation for the AI chatbot. What's more, users are being upgraded to the new GPT-5.6 Luna model by default. This brings improvements in reasoning, accuracy, and overall conversational quality. To access this, update your ChatGPT app or visit the website and sign in. The rollout is automatic and may take a few days to reach everyone. GPT-5.6 Luna offers 62 percent better factual accuracy than the previous version. It also introduces a "Think button" for complex queries, allowing ChatGPT more time to reason before responding. While Free and Go users get Luna, paid subscribers receive the even more advanced GPT-5.6 Sol model. This makes ChatGPT significantly more accessible for everyday tasks like writing, coding, and research.
