# Quickstart

> Integrate Opik with your LLM application to log calls and chains efficiently. Get started with our step-by-step guide.

This guide helps you integrate the Opik platform with your existing LLM application. The goal of
this guide is to help you log your first LLM calls and chains to the Opik platform.

## Prerequisites

Before you begin, you'll need to choose how you want to use Opik:

* **Opik Cloud**: Create a free account at [comet.com/opik](https://www.comet.com/signup?from=llm\&utm_source=opik\&utm_medium=colab\&utm_content=quickstart\&utm_campaign=opik)
* **Self-hosting**: Follow the [self-hosting guide](/self-host/overview) to deploy Opik locally or on Kubernetes

## Logging your first LLM calls

Opik makes it easy to integrate with your existing LLM application, here are some of our most
popular integrations:

<Tabs>
  <Tab title="Python SDK" value="python-function-decorator">
    If you are using the Python function decorator, you can integrate by:

    <Steps>
      <Step>
        Install the Opik Python SDK:

        ```bash
        pip install opik
        ```
      </Step>

      <Step>
        Configure the Opik Python SDK:

        ```bash
        opik configure
        ```
      </Step>

      <Step>
        Wrap your function with the `@track` decorator:

        ```python
        from opik import track

        @track
        def my_function(input: str) -> str:
            return input
        ```

        All calls to the `my_function` will now be logged to Opik. This works well for any function
        even nested ones and is also supported by most integrations (just wrap any parent function
        with the `@track` decorator).
      </Step>
    </Steps>
  </Tab>

  <Tab title="TypeScript SDK" value="typescript-sdk">
    If you want to use the TypeScript SDK to log traces directly:

    <Steps>
      <Step>
        Install the Opik TypeScript SDK:

        ```bash
        npm install opik
        ```
      </Step>

      <Step>
        Configure the Opik TypeScript SDK by running the interactive CLI tool:

        ```bash
        npx opik-ts configure
        ```

        This will detect your project setup, install required dependencies, and help you configure environment variables.
      </Step>

      <Step>
        Log a trace using the Opik client:

        ```typescript
        import { Opik } from "opik";

        const client = new Opik();

        const trace = client.trace({
          name: "My LLM Application",
          input: { prompt: "What is the capital of France?" },
          output: { response: "The capital of France is Paris." },
        });

        trace.end();
        await client.flush();
        ```

        All traces will now be logged to Opik. You can also log spans within traces for more detailed observability.
      </Step>
    </Steps>
  </Tab>

  <Tab title="OpenAI (Python)" value="openai-python-sdk">
    If you are using the OpenAI Python SDK, you can integrate by:

    <Steps>
      <Step>
        Install the Opik Python SDK:

        ```bash
        pip install opik
        ```
      </Step>

      <Step>
        Configure the Opik Python SDK, this will prompt you for your API key if you are using Opik
        Cloud or your Opik server address if you are self-hosting:

        ```bash
        opik configure
        ```
      </Step>

      <Step>
        Wrap your OpenAI client with the `track_openai` function:

        ```python
        from opik.integrations.openai import track_openai
        from openai import OpenAI

        # Wrap your OpenAI client
        client = OpenAI()
        client = track_openai(client)

        # Use the client as normal
        completion = client.chat.completions.create(
            model="gpt-4o",
            messages=[
                {"role": "user", "content": "Hello, how are you?",
                },
            ],
        )
        print(completion.choices[0].message.content)
        ```

        All OpenAI calls made using the `client` will now be logged to Opik. You can combine
        this with the `@track` decorator to log the traces for each step of your agent.
      </Step>
    </Steps>
  </Tab>

  <Tab title="OpenAI (TS)" value="openai-ts-sdk">
    If you are using the OpenAI TypeScript SDK, you can integrate by:

    <Steps>
      <Step>
        Install the Opik TypeScript SDK:

        ```bash
        npm install opik-openai
        ```
      </Step>

      <Step>
        Configure the Opik TypeScript SDK by running the interactive CLI tool:

        ```bash
        npx opik-ts configure
        ```

        This will detect your project setup, install required dependencies, and help you configure environment variables.
      </Step>

      <Step>
        Wrap your OpenAI client with the `trackOpenAI` function:

        ```typescript
        import OpenAI from "openai";
        import { trackOpenAI } from "opik-openai";

        // Initialize the original OpenAI client
        const openai = new OpenAI({
          apiKey: process.env.OPENAI_API_KEY,
        });

        // Wrap the client with Opik tracking
        const trackedOpenAI = trackOpenAI(openai);

        // Use the tracked client just like the original
        const completion = await trackedOpenAI.chat.completions.create({
          model: "gpt-4",
          messages: [{ role: "user", content: "Hello, how can you help me today?" }],
        });
        console.log(completion.choices[0].message.content);

        // Ensure all traces are sent before your app terminates
        await trackedOpenAI.flush();
        ```

        All OpenAI calls made using the `trackedOpenAI` will now be logged to Opik.
      </Step>
    </Steps>
  </Tab>

  <Tab title="AI Vercel SDK" value="ai-vercel-sdk">
    If you are using the AI Vercel SDK, you can integrate by:

    <Steps>
      <Step>
        Install the Opik Vercel integration:

        ```bash
        npm install opik-vercel
        ```
      </Step>

      <Step>
        Configure the Opik AI Vercel SDK by running the interactive CLI tool:

        ```bash
        npx opik-ts configure
        ```

        This will detect your project setup, install required dependencies, and help you configure environment variables.
      </Step>

      <Step>
        Initialize the OpikExporter with your AI SDK:

        ```ts
        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";

        // Set up OpenTelemetry with Opik
        const sdk = new NodeSDK({
          traceExporter: new OpikExporter(),
          instrumentations: [getNodeAutoInstrumentations()],
        });
        sdk.start();

        // Your AI SDK calls with telemetry enabled
        const result = await generateText({
          model: openai("gpt-4o"),
          prompt: "What is love?",
          experimental_telemetry: { isEnabled: true },
        });

        console.log(result.text);
        ```

        All AI SDK calls with `experimental_telemetry: { isEnabled: true }` will now be logged to Opik.
      </Step>
    </Steps>
  </Tab>

  <Tab title="Ollama" value="ollama-python">
    If you are using Ollama with Python, you can integrate by:

            print(result)
            ```
          </Tab>

          <Tab title="OpenAI SDK">

        Track your LangGraph graph with `track_langgraph`:

        ```python
        from opik.integrations.langchain import OpikTracer, track_langgraph

        # Create your LangGraph graph
        graph = ...
        app = graph.compile(...)

        # Create OpikTracer and track the graph once
        # The graph visualization is automatically extracted by track_langgraph
        opik_tracer = OpikTracer()
        app = track_langgraph(app, opik_tracer)

        # Now all invocations are automatically tracked!
        result = app.invoke({"messages": [HumanMessage(content = "How to use LangGraph ?")]})

    The pre-built prompt will guide you through the integration process, install the Opik SDK and
    instrument your code. It supports both Python and TypeScript codebases, if you are using
    another language just let us know and we can help you out.

## Analyze your traces

After running your application, you will start seeing your traces in your Opik dashboard:

<video src="https://files.buildwithfern.com/https://opik.docs.buildwithfern.com/docs/opik/2026-01-30T17:33:07.444Z/img/tracing/quickstart.mp4" width="854" height="480" autoPlay muted loop playsInline preload="auto" />

If you don't see traces appearing, reach out to us on [Slack](https://chat.comet.com) or raise an issue on [GitHub](https://github.com/comet-ml/opik/issues) and we'll help you troubleshoot.
