With the launch of o3-pro, lets talk about what AI reasoning actually does

OpenAI has introduced o3-pro, a new version of its advanced reasoning model, now available to ChatGPT Pro and Team users, replacing o1-pro and offering enhanced capabilities such as web search, file and image analysis, and Python execution. Despite these improvements, the model's slower response times and persistent factual inaccuracies highlight ongoing challenges in AI reasoning, raising questions about what "reasoning" truly entails in these systems. In addition to technical upgrades, OpenAI has significantly reduced the pricing for o3-pro by 87 percent compared to o1-pro, with costs now at $20 per million input
