Vercel AI SDK

Choose a setup method

Method	Use it when
Agnost AI skill	You want your coding agent to inspect the app, make the change, and verify it.
Agnost AI SDK	You want explicit control over the interaction boundaries and fields.
OpenTelemetry	The framework already emits useful spans or you operate an OTel pipeline.

Start with one method for a call path. Combining SDK tracking with framework OpenTelemetry on the same call can create duplicate interactions.

Recommended: Agnost AI skill

Recommended. Choose this path when you want your coding agent to inspect the project, select a supported transport, make the smallest instrumentation change, send a test event, and verify that it reached Agnost AI.

Install the skill once in your coding-agent environment:

npx skills add AgnostAI/skills --skill agnost-ai

Run the framework-specific prompt below from the application root. Review the resulting diff before deploying it.

Use the agnost-ai skill to add Agnost AI analytics to this Vercel AI SDK application.
Org ID: your-org-id
Instrument the real generateText() or streamText() path and verify one fresh interaction.

Manual setup: Agnost AI SDK

npm install agnostai

import { generateText } from 'ai';
import * as agnost from 'agnostai';

agnost.init('your-org-id');
const interaction = agnost.begin({ userId: 'u-42', agentName: 'vercel-ai-support', input: prompt });
try {
  const { text } = await generateText({ model, prompt });
  interaction.end(text);
} catch (error) {
  interaction.end(String(error), false);
  throw error;
} finally {
  await agnost.shutdown();
}

Manual setup: OpenTelemetry

The Vercel AI SDK emits ai.* spans natively. Wire an OTel exporter pointing at Agnost AI, then enable telemetry per call with userId / sessionId.

1. Install

Already have @opentelemetry/sdk-node (or another OTel SDK) and @opentelemetry/exporter-trace-otlp-proto? Skip: you only need the existing packages. No OTel set up yet?

npm install @opentelemetry/sdk-node @opentelemetry/exporter-trace-otlp-proto

2. Wire the OTel exporter pointing at Agnost AI

Already exporting OTel? Append Agnost AI as an additional span processor on your existing TracerProvider:

import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-base';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';

provider.addSpanProcessor(
  new BatchSpanProcessor(
    new OTLPTraceExporter({
      url: 'https://otel.agnost.ai/v1/traces',
      headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
    }),
  ),
);

No OTel yet? Boot a NodeSDK at startup (e.g. Next.js instrumentation.ts):

import { NodeSDK } from '@opentelemetry/sdk-node';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';

new NodeSDK({
  traceExporter: new OTLPTraceExporter({
    url: 'https://otel.agnost.ai/v1/traces',
    headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
  }),
}).start();

3. Pass userId / sessionId per call

import { generateText } from 'ai';

await generateText({
  model: openai('gpt-4o'),
  prompt: 'Hello',
  experimental_telemetry: {
    isEnabled: true,
    metadata: {
      userId: 'user-42',
      sessionId: 'conv-abc123',
    },
  },
});

experimental_telemetry.isEnabled defaults to false: set it per call.

What appears in Agnost AI

Conversations grouped by sessionId.
User-level analytics grouped by userId.
Events for every generated span.

Verify

Run one generateText call, then open Events in Agnost AI. If the event is present, check Conversations for session grouping.
