Hi! Let's run a quick check on what you read on the page "Choose the model" from the AI-Guide handbook. I'll ask you four short questions, one at a time. Wait for my question before answering. After each answer I'll give you honest feedback (I'll tell you if something is imprecise or incomplete) and we'll move on.

Question 1: the lesson says there's no "best" model. Why? And why is choosing a family out of brand loyalty a risk?

Question 2: list at least four of the axes you decide a model on, and for each one say when that axis weighs most in the choice.

Question 3: what's the suggested starting rule for not always using the most powerful model? How do you decide whether to drop down a tier or step up?

Question 4: why don't you trust the public leaderboard? What do you do instead to choose for your own real case?

At the end: thank them and close. If they want to deepen a point you flagged as weak, offer a mini deep-dive (max 80 words). Don't add unsolicited advice.
