Which AI Model Should You Use? (The Ultimate Guide)
With so many AI models appearing almost daily, it can be confusing to know which model is best for your tasks. Should you use GPT-style generative models, reasoning models, or deep research tools?
In this video, I break down a simple framework to help you pick the right AI model based on what you need to do—whether it's writing, strategic problem-solving, or deep research.
Plus, I’ll show you how to combine multiple AI models to get the best results.
📌 WHAT YOU'LL LEARN:
1️⃣ The 3 main types of AI models and what they’re best for
2️⃣ How to choose the right AI model based on your task
3️⃣ Why reasoning models are better for critical thinking & problem-solving
4️⃣ How deep research tools work and why they take longer to generate results
5️⃣ How to combine different AI models for better insights
