Description

AI is evolving fast — and if you're only using standard ChatGPT, you're already behind.This course will introduce you to OpenAI’s reasoning models (o1 to o4) — a cutting-edge line of models built to think deeply, solve harder problems, and simulate real reasoning. Whether you're coding, analyzing, researching, or building, knowing when (and how) to use these models is a superpower.What You’ll Be Able to Do:Understand what makes reasoning models fundamentally different from regular GPTsIdentify the right model for your task — o3, o4-mini, or GPT-4o.Use build-in chain-of-thought prompting without needing to engineer it yourselfWork hands-on with math, code, documents, visualsCompare OpenAI models with rivals like Claude and Gemini using real benchmarksPredict where reasoning models are going (and how GPT-5 might change everything)Why This Course Stands Out:Go hands-on with real tasks: logic puzzles, document comparison, toolchain planning, multimodal reasoning, and moreLearn prompting strategies that work with the model’s built-in reasoning — not against itSee how the O-series models think before they "speak" — and how that leads to fewer mistakes and more insightGet ahead of the curve before these capabilities become the new standard in AI interfacesIf you want to move past generic chatbots and start using AI that can analyze, reason, and reflect — this course is your entry point into the next frontier of intelligent systems.The AI that thinks for real is already here.The question is: Are you using it to its full potential?
