<ul data-eligibleForWebStory="true">OpenAI launched o3-pro, a new simulated reasoning model, available to ChatGPT Pro and Team users, replacing o1-pro.o3-pro focuses on mathematics, science, coding, web search, file analysis, image analysis, and Python execution.The model is slower but recommended for complex problems where accuracy is more important than speed.Price reductions for o3-pro make it 87% cheaper than o1-pro, addressing concerns about high costs.o3-pro utilizes chain-of-thought simulated reasoning for technical challenges, prioritizing accuracy over speed.OpenAI reports positive feedback on o3-pro's performance and preferences over o3 in various domains.Research suggests that reasoning models like o3-pro allocate more resources for improved analytical task performance.AI models using chain-of-thought techniques enhance accuracy by constraining outputs and considering context.However, Transformer-based AI models primarily rely on pattern matching from training data.While pattern-matching and reasoning are not mutually exclusive, limitations exist in current AI models' logical reasoning abilities.
