Choosing the Right AI Brain for Your Business: o3 vs o4‑mini

The AI Revolution, Simplified

If you've started exploring AI for your business—or you're about to—you've likely encountered OpenAI's newest models: o3 and o4‑mini. But which one deserves your attention? Let's cut through the complexity and help you make a confident choice.

Understanding AI Models in Plain English

When you use ChatGPT, you're interacting with an AI "model"—essentially the brain powering your conversation. Think of it as choosing between different types of consultants: some excel at deep strategic thinking, while others specialise in quick, efficient everyday tasks.

o4‑mini: The Efficient Assistant
