What changed
Google introduced the Gemini Decisions API on November 11 for bounded multimodal choices. The announcement describes scoring candidate options rather than generating a free-form answer.
Why it matters
A confidence score is useful only when it helps a system make better decisions on its own data. A router may need to decline an ambiguous case instead of always choosing a tool. Keep the consequences of a wrong route visible: sending a harmless query to a slower model is different from approving an irreversible action.
What to check next
Create a labeled validation set that includes ambiguous inputs and cases outside the intended categories. Measure error rates by confidence band, set a fallback threshold and retest after distribution changes. Treat the announcement as vendor evidence; Codorc has not independently benchmarked this API.
