AI SDK Example | isplay Docs

AI SDK v6 applies model middleware with wrapLanguageModel. isplay exposes a typed middleware plus a convenience wrapper.

import { generateText, tool } from "ai";
import { z } from "zod";
import { init } from "@isplay/sdk";
import { instrumentTools, wrapIsplayModel } from "@isplay/adapter-ai-sdk";

const client = init({
  projectId: process.env.ISPLAY_PROJECT_ID!,
  baseUrl: process.env.ISPLAY_API_URL,
  serviceName: "ai-sdk-agent",
});

const model = wrapIsplayModel(yourModel, {
  client,
  provider: "openai",
  model: "gpt-5.4-mini",
});

const tools = instrumentTools(
  {
    lookup_claim: tool({
      description: "Look up claim details",
      inputSchema: z.object({ claimId: z.string() }),
      __isplaySideEffectClass: "read",
      __isplaySchemaVersion: "1",
      execute: async ({ claimId }) => ({ claimId, eligible: true }),
    }),
  },
  { client }
);

await client.withRun({ name: "ai-sdk-run" }, async () => {
  await generateText({
    model,
    prompt: "Review claim C-104",
    tools,
  });
});

Drain streamText streams so the middleware can write final model output and tool proposal records.
