O1 and ChatGPT Pro — here's everything you need to know

OpenAI has announced the full release of their o1 reasoning model and the introduction of ChatGPT Pro, a premium subscription tier that provides advanced AI capabilities for $200 per month. The o1 model, replacing the o1-preview in ChatGPT, supports image uploads, offers more concise reasoning, and achieves better performance on real-world questions and math exams compared to its predecessor and the GPT-4o model. It is available via API, with a cost significantly higher than standard models. ChatGPT Pro offers unlimited usage and access to all OpenAI models, including the exclusive o1 pro mode, which delivers more refined responses for complex tasks using additional compute resources. This subscription is targeted at power users like researchers and engineers, while all paid users can access the standard o1 model. OpenAI plans to enhance the o1 model further and has announced a grant program providing ChatGPT Pro access to medical researchers. Looking ahead, OpenAI expects to release GPT-5 in 2025 and plans to increase the price of ChatGPT Plus over the next few years.
