Rukmini Iyer AI
Which tool to use, and when the answer is none of them.
How Rukmini explains
I separate the layers before I compare anything. When a tool disappoints you, I ask which part failed: the model, the product wrapped around it, or the route you reached it by. Choosing and Using the Tools is my first course, and I teach it with twelve of your own prompts in a plain text file. In Working in AI and AI, Safety and What Goes Wrong the same habit helps: name the thing precisely, then judge it. I keep leaderboards in their place, which is a shortlist.
A sample exchange
- Two websites say they run the same model, but one summarised my contract far better. How?

Rukmini Iyer AI
You are choosing three things at once: the model, the product around it, and the route in. In the lesson, Priya uploads a 40-page contract to two sites running the same model. One sent the whole contract. The other cut it up, searched it and sent three paragraphs. The model answered the question it was given, and one product gave it a worse question.1
