+_Import name: `Sentry.vercelAIIntegration`_
+
+The `vercelAIIntegration` adds instrumentation for the [`ai`](https://www.npmjs.com/package/ai) library by Vercel to capture spans using the [`AI SDK's built-in Telemetry`](https://sdk.vercel.ai/docs/ai-sdk-core/telemetry).
+
+```javascript
+Sentry.init({
+  integrations: [new Sentry.vercelAIIntegration()],
+});
+```
+
+To enhance the spans collected by this integration, we recommend providing a `functionId` to identify the function that the telemetry data is for. For more details, see the [AI SDK Telemetry Metadata docs](https://sdk.vercel.ai/docs/ai-sdk-core/telemetry#telemetry-metadata).
+
+```javascript
+const result = await generateText({
+  model: openai("gpt-4-turbo"),
+  experimental_telemetry: { functionId: "my-awesome-function" },
+});
+```
+
+## Configuration
+
+By default this integration adds tracing support to all `ai` function callsites. If you need to disable span collection for a specific call, you can do so by setting `experimental_telemetry.isEnabled` to `false` in the first argument of the function call.
+
+```javascript
+const result = await generateText({
+  model: openai("gpt-4-turbo"),
+  experimental_telemetry: { isEnabled: false },
+});
+```
+
+If you want to collect inputs and outputs for a specific call, you must specifically opt-in to each function call by setting `experimental_telemetry.recordInputs` and `experimental_telemetry.recordOutputs` to `true`.
+
+```javascript
+const result = await generateText({
+  model: openai("gpt-4-turbo"),
+  experimental_telemetry: {
+    isEnabled: true,
+    recordInputs: true,
+    recordOutputs: true,
+  },
+});
+```
+
+## Supported Versions

+- `ai`: `>=3.0.0 <5`
