Comment on: OpenRouter Model Fusion

Most multi-model tools optimize the wrong step. Routing is easy. Synthesis is the hard part. The fact that the judge model is configurable is actually the interesting design decision here, not the parallel execution. A judge that just averages or picks longest is no better than a single good model. Curious whether the default judge behavior is documented somewhere, or if the quality of the fusion is mostly opaque until you've run it enough times to calibrate it yourself.
