what's actually running

One model, made of models.

A fusion model is one model, made of models. Each one votes; we weight every vote by how it scored on a handful of calibration questions, then aggregate with differential-privacy noise so no single source can dominate the answer. A mixture of experts — made honest. And the whole thing is a URL you can run.
