OpenAI has announced the removal of limits on text chats for all ChatGPT users, coinciding with the platform surpassing 1 billion weekly users. The new GPT-5.6 Luna model will be the default for Free and Go users, while Plus and Pro users will access an upgraded GPT-5.6 Sol model, designed for efficiency in tasks like research and decision-making.
Additionally, Plus and Pro users will receive a thinking slider to customize the depth of responses. These updates aim to enhance user experience by providing more accurate and concise answers, with significant reductions in factual errors compared to previous models.
