If a product can switch between Claude, DeepSeek, and GPT, what is it more like?

Answer: A platform that routes across models

One model that answers everything — Wrong. If something can switch across several models, it is almost certainly not one model itself. A single model can be called by the platform, but it is not the platform.

A platform that routes across models ✓ — Correct! A product that can switch among Claude, DeepSeek, and GPT behaves like a routing or orchestration layer. It sits above the models and decides which one to use, when to use it, and sometimes how to combine them.

The data used to train those models — Wrong. Training data is what helps create model capability before deployment. It does not sit at runtime deciding which model should answer a user request.
