Qwen prompt volatility tracking

qwenprompt_volatilityAccount required

Qwen's commercial answers are noticeably more volatile than its informational ones, because product surfaces beneath it change faster than reference content does.

How it renders

Derived across the sample set, reported per intent bucket.

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

High volatility on a commerce prompt often reflects genuine catalogue churn rather than model instability. Diagnose before you report it as noise.

What the API returns

A single collection call against Qwen for the prompt volatility field, sampled n times and returned as one object per prompt.
