OpenAI has made its latest AI models, o1-preview and o1-mini, available to all ChatGPT Enterprise and ChatGPT Edu customers. Designed to tackle complex reasoning tasks, these models could change the way businesses and educational institutions approach their toughest challenges. As Michael Nuñez reports for VentureBeat, the o1 models stand out for their ability to engage in deep, multi-level thinking. In early tests, o1-preview performed impressively, solving 83% of the problems on a qualifying exam for the International Math Olympiad.
