Key takeaways · AI-distilled
Vercel says the citations Parallel Decisions returns cover the whole request. They do not tie individual sources to individual answers, so you cannot trace which source backed which answer when you ask several questions at once.
Vercel suggests using the returned probabilities as a routing signal: act automatically when an answer clears a threshold you set, and send uncertain results to a person for review.
The three question types behave differently: Boolean returns the probability of yes, Choice picks from options you define, and Score rates against an ordered rubric. Requests show up in AI Gateway logs and spend budgets like other model calls.
