Opik Vercel AI SDK Integration

Seamlessly integrate Opik observability with your Vercel AI SDK applications to trace, monitor, and debug your AI workflows.

Features

• 🔍 Comprehensive Tracing: Automatically trace AI SDK calls and completions
• 📊 Hierarchical Visualization: View your AI execution as a structured trace with parent-child relationships
• 📝 Detailed Metadata Capture: Record model names, prompts, completions, token usage, and custom metadata
• 🚨 Error Handling: Capture and visualize errors in your AI API interactions
• 🏷️ Custom Tagging: Add custom tags to organize and filter your traces
• 🔄 Streaming Support: Full support for streamed completions and chat responses

Installation

Node.js

npm install opik-vercel ai @ai-sdk/openai @opentelemetry/sdk-node @opentelemetry/auto-instrumentations-node

Next.js

npm install opik-vercel @vercel/otel @opentelemetry/api-logs @opentelemetry/instrumentation @opentelemetry/sdk-logs

Requirements

• Node.js ≥ 18
• Vercel AI SDK (ai ≥ 3.0.0)
• Opik SDK (automatically installed as a peer dependency)
• OpenTelemetry packages (see installation commands above)

Configuration

Set your environment variables:

OPIK_API_KEY="<your-api-key>"
OPIK_URL_OVERRIDE="https://www.comet.com/opik/api"  # Cloud version
OPIK_PROJECT_NAME="<custom-project-name>"
OPIK_WORKSPACE="<your-workspace>"
OPENAI_API_KEY="<your-openai-api-key>"  # If using OpenAI models

Usage

Node.js

import { openai } from "@ai-sdk/openai";
import { generateText } from "ai";
import { NodeSDK } from "@opentelemetry/sdk-node";
import { getNodeAutoInstrumentations } from "@opentelemetry/auto-instrumentations-node";
import { OpikExporter } from "opik-vercel";

const sdk = new NodeSDK({
  traceExporter: new OpikExporter(),
  instrumentations: [getNodeAutoInstrumentations()],
});

sdk.start();

async function main() {
  const result = await generateText({
    model: openai("gpt-5-nano"),
    maxTokens: 50,
    prompt: "What is love?",
    experimental_telemetry: OpikExporter.getSettings({
      name: "opik-nodejs-example",
    }),
  });

  console.log(result.text);

  await sdk.shutdown(); // Flushes the trace to Opik
}

main().catch(console.error);

Next.js

For Next.js applications, use the framework's built-in OpenTelemetry support:

// instrumentation.ts
import { registerOTel } from "@vercel/otel";
import { OpikExporter } from "opik-vercel";

export function register() {
  registerOTel({
    serviceName: "opik-vercel-ai-nextjs-example",
    traceExporter: new OpikExporter(),
  });
}

Then use the AI SDK with telemetry enabled:

import { openai } from "@ai-sdk/openai";
import { generateText } from "ai";

const result = await generateText({
  model: openai("gpt-5-nano"),
  prompt: "What is love?",
  experimental_telemetry: { isEnabled: true },
});

Advanced Configuration

Custom Tags and Metadata

You can add custom tags and metadata to all traces generated by the OpikExporter:

const exporter = new OpikExporter({
  // Optional: add custom tags to all traces
  tags: ["production", "gpt-5-nano"],
  // Optional: add custom metadata to all traces
  metadata: {
    environment: "production",
    version: "1.0.0",
    team: "ai-team",
  },
  // Optional: associate traces with a conversation thread
  threadId: "conversation-123",
});

Tags are useful for filtering and grouping traces, while metadata adds additional context for debugging and analysis. The threadId parameter is useful for tracking multi-turn conversations or grouping related AI interactions.

Telemetry Settings

Use OpikExporter.getSettings() to configure telemetry for individual AI SDK calls:

const result = await generateText({
  model: openai("gpt-5-nano"),
  prompt: "Tell a joke",
  experimental_telemetry: OpikExporter.getSettings({
    name: "custom-trace-name",
    // Optional: set threadId per request (overrides exporter-level threadId)
    metadata: {
      threadId: "conversation-456",
    },
  }),
});

Or use the basic telemetry settings:

const result = await generateText({
  model: openai("gpt-5-nano"),
  prompt: "Tell a joke",
  experimental_telemetry: { isEnabled: true },
});

Viewing Traces

To view your traces:

1. Sign in to your Comet account
2. Navigate to the Opik section
3. Select your project to view all traces
4. Click on a specific trace to see the detailed execution flow

Debugging

To enable more verbose logging for troubleshooting:

OPIK_LOG_LEVEL=DEBUG
