OpenAI announced a series of major updates to ChatGPT, removing message limits on text-based conversations for free tier users while rolling out advanced reasoning tools to enhance answer accuracy. The update introduces a dedicated "Think" feature designed to tackle complex
analytical queries, alongside upgrading the default standard model to GPT-5.6 Luna for routine daily tasks. Furthermore, premium subscribers gained access to the upgraded GPT-5.6 Sol model, which delivers higher factual precision regarding dates, numerical data, and source citations, accompanied by
a dynamic reasoning slider that allows users to adjust the cognitive processing depth prior to response generation.
