Microsoft Copilot prompt volatility tracking
copilotprompt_volatilityAnonymous
Copilot is comparatively stable because it leans on a fixed index rather than a fan-out process, so volatility scores here run lower than on the Google surfaces.
How it renders
Derived across the sample set.
Sampling
Volatility is what tells you the right n for every other field. We recommend using it to allocate credits: sample noisy prompts deeply, stable prompts lightly.
Gotcha
Stability driven by index dependence means Copilot movement usually reflects a Bing index change, not an AI behaviour change. Diagnose accordingly.
What the API returns
A single collection call against Microsoft Copilot for the prompt volatility field, sampled n times and returned as one object per prompt.
