I built a desktop app that sends one prompt to up to 16 models side by side, and the most interesting thing I’ve learned isn’t technical. It’s how often they disagree.

Ask a factual question and the answers mostly match. Ask anything about judgment, like legal wording, a business decision or a medical “should I”, and you get several confident answers that contradict each other. When you only use one model, you never see that.

It changed how I use AI. I no longer trust any single answer. I look for where the models agree, and I dig into where they don’t.
