OpenAI has introduced two cutting-edge AI models — 03 and o4-mini — that represent a major leap toward more intelligent, tool-using AI systems. These new O-series models don’t just respond — they reason, leveraging deeper contextual understanding and the ability to autonomously use tools like web browsing, file analysis, and image interpretation. 03 is now OpenAI’s most capable model, outperforming the previous 01 model in coding, math, science, and visual tasks. It also makes 20% fewer major mistakes on real-world challenges. On the other hand, o4-mini is built for speed and lightweight tasks, but still delivers top-tier performance — scoring an impressive 99.5% on AIME 2025 and outshining 03-mini in non-STEM reasoning and data science tasks. These models are the first to fully integrate with all ChatGPT tools, laying the groundwork for a more autonomous, agent-like AI experience. Starting today, 03, o4-mini, and o4-mini-high are available to ChatGPT Plus, Pro, and Team users, replacing older 01 and mini models. Enterprise and Edu users will gain access next week, while free-tier users can try o4-mini by selecting the new “Think” mode. Up next? o3-pro — a new model arriving soon with even more advanced reasoning and full tool support. #OpenAI #ChatGPT #AInews #TechUpdate #StartupTracker #ArtificialIntelligence #ProductLaunch
