@swoosh-dev/ai-sdk

Vercel AI SDK provider adapter for @swoosh-dev/router. Kept separate so the core router stays free of the ai dependency — install this only if you route through the AI SDK.

npm install @swoosh-dev/ai-sdk ai

import { ModelRouter, ModelsDevCapabilityCatalog } from "@swoosh-dev/router";
import { createAiSdkProviderAdapter } from "@swoosh-dev/ai-sdk";
import { google } from "@ai-sdk/google";
import { generateObject } from "ai";

const router = new ModelRouter({
  catalog: new ModelsDevCapabilityCatalog(),
  providers: [
    createAiSdkProviderAdapter({
      providerId: "google",
      models: { "gemini-2.5-flash": google("gemini-2.5-flash") },
      generateObject: (request) => generateObject(request as never),
    }),
  ],
});

models maps each modelId from the catalog to its AI SDK model instance; the router picks the capability and this adapter resolves and calls it. ai is a peer dependency.
