## What is a personal benchmark?

A personal benchmark tells you which AI model is best for the work you actually do. It takes a real task—say, giving feedback on an article opening—and gives it to several models. Then it scores their answers against your standards: Did it catch that the headline buried the strongest claim? Did it replace vague language with concrete wording? Each time you correct an AI, that correction can become another test. Over time, your benchmark gives you a living, personalized answer to a practical question: Which model should I use for this job?
