Parallel Decisions now available on AI Gateway for free

Vercel added Parallel Decisions Fast from Parallel to AI Gateway, free through November 23, 2026, under the model name `parallel/parallel-decisions-fast`. The model searches the live web to answer typed questions about companies, products and policies, returning probabilities with cited evidence; boolean questions return the probability of yes, choice questions select from developer-defined options, and score questions assess an ordered rubric, with related questions sharing context and retrieved evidence in one request. No separate Parallel account is required, and AI Gateway tracks the requests in its logs and spend budgets alongside other model requests.
