OpenAI Announces a New AI Model That Solves Difficult Problems Step by Step

OpenAI made the last big breakthrough in artificial intelligence by increasing the size of its models to dizzying proportions, when it introduced GPT-4 last year. The company today announced a new advance that signals a shift in approach--a model that can "reason" logically through many difficult problems and is significantly smarter than existing AI without a major scale-up. The new model, dubbed OpenAI-o1, can solve problems that stump existing AI models, including OpenAI's most powerful existing model, GPT-4o. Rather than summon up an answer in one step, as a large language model normally does, it reasons through the problem, effectively thinking out loud as a person might, before arriving at the right result. "This is what we consider the new paradigm in these models," Mira Murati, OpenAI's chief technology officer, tells WIRED.
