The routing decision

Same request. Different winner.

A router scores every model against criteria, then sends your request to whichever wins. Move the slider to change what the criteria reward.

Illustrative figures, not any real vendor's prices — the mechanic is the point, not the numbers. Nothing here is hidden from you. That is the only part that is unrealistic.
