Vercel adds Parallel Decisions Fast to AI Gateway, free until Nov 23

Vercel's AI Gateway now carries Parallel Decisions Fast, a model from Parallel that queries the live web to answer questions about companies, products, policies and other facts that shift over time. Instead of prose, it returns probabilities backed by cited evidence. Vercel says developers call it as parallel/parallel-decisions-fast and need no separate Parallel account; it is free through November 23, 2026. Three question types are supported: boolean questions return a likelihood of yes, choice questions pick from options the caller defines, and score questions grade against an ordered rubric. Citations list source URLs, optional titles and evidence excerpts, and apply to the whole request rather than to individual answers. Requests show up in gateway logs and spend budgets.
