Selection Rate
The rate at which an AI system chooses a given source from the available grounding candidates when composing an answer; the AI-search equivalent of click-through rate.
Selection Rate is the rate at which an AI system chooses a given source from the grounding candidates available to it when it composes an answer. It is the AI-search equivalent of click-through rate: where CTR captured a person picking a link from a list, Selection Rate captures a model picking a source to ground its reply on.
Raising it is the aim of Selection Rate Optimization. Related: AI Visibility.
