Since OpenAI introduced the “Reasoning Models” like o3, o4-mini, or o4-mini-high, one thing has become clear: 👉 Choosing a model is no longer a technical decision — it's a strategic one. And that, understandably, is causing a great deal of confusion: ✅ The model names are vague, interchangeable, and not particularly intuitive. ✅ The differences are poorly documented or difficult to find. ✅ Many users are using the wrong model — and are puzzled by the results. 🎯 Here's how we bring clarity: I've reviewed OpenAI’s official guidance and condensed it into a simple, decision-oriented flowchart to help you choose the right model based on your goals: ✅ Multimodal, everyday use, speed? → GPT-4o ✅ Structuring, organizing, planning? → o4-mini or o4-mini-high ✅ Deep reasoning, understanding, analysis? → o3 or o3-mini 💡 The key to choosing between the o3 and o4 models lies in a simple question: Do I want to understand (Why?) — or execute (How?). You can download the model selection cheat sheet here — and feel free to share it. - Are you already using the right models? - Or were you unaware that this distinction even existed? - Which models do you rely on in your daily work? P.S. If you want to prompt strategically, it's not enough to just ask the AI — you also need to know who you're talking to. 🤪
