Vercel AI Gateway adds Google's decision-only Gemini Decision 1 model

Vercel added Google's Gemini Decision 1, a non-generative decision model, to its AI Gateway, giving developers a single API key for routing, policy checks, and agent tool filtering.

Vercel announced on November 11, 2026, that it had added Google's new Gemini Decision 1, a non-generative decision model, to its AI Gateway, according to a Vercel changelog entry. The model gives developers a single API key to use it for routing, policy checks, and agent tool filtering alongside Vercel's existing observability and billing tools.

What Gemini Decision 1 adds to the Gateway

The model is available under the identifier google/gemini-decision-1.
It accepts multimodal inputs: text, images, audio, video, and PDF documents.
Outputs are non-generative: booleans, choices, and scores rather than text tokens.
Developers can reach it through three paths: the AI SDK's experimental_decide function, a TypeSafe-compatible API, and a dedicated Decisions API.
PDF, audio, and video inputs require AI SDK 7; the TypeSafe-compatible API and the Decisions API support only text and image.
It plugs into AI Gateway's unified spend tracking, observability logs, and request traces, using one API key with no separate Google provider account required.

What it means for people building with AI

For teams building multi-step coding or automation agents on Vercel, the addition makes a new, cheaper, non-generative model category usable directly inside existing pipelines. Stated use cases include routing requests, policy checking, filtering agent tools, and ranking results, work that previously needed either a separate Google Cloud account or a full generative model.

Context among recent AI Gateway additions

Gemini Decision 1's listing follows two other AI Gateway additions published on November 10, 2026: MiniMax H3 Image/Highspeed and Gemini 4 Carbon, which confirms the November 11 placement. The changelog entry is credited to Vercel staff authors Aayush Kapoor, Jerilyn Zheng, and Zachary Chen.
