# OpenAI

> Migrate your OpenAI model to Runpod

To get started with Runpod:

* [Create a Runpod account](/get-started/manage-accounts)
* [Add funds](/references/billing-information)
* [Use the Runpod SDK](/serverless/overview) to build and connect with your Serverless Endpoints

This tutorial guides you through the steps necessary to modify your OpenAI Codebase for use with a deployed vLLM Worker on Runpod. You will learn to adjust your code to be compatible with OpenAI's API, specifically for utilizing Chat Completions, Completions, and Models routes. By the end of this guide, you will have successfully updated your codebase, enabling you to leverage the capabilities of OpenAI's API on Runpod.

To update your codebase, you need to replace the following:

* Your OpenAI API Key with your Runpod API Key
* Your OpenAI Serverless Endpoint URL with your Runpod Serverless Endpoint URL
* Your OpenAI model with your custom LLM model deployed on Runpod

    ```python theme={null}

    from openai import OpenAI
    import os

    client = OpenAI(
    api_key=os.environ.get("RUNPOD_API_KEY"),
    base_url="https://api.runpod.ai/v2/${YOUR_ENDPOINT_ID}/openai/v1",
    )

    response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "Why is Runpod the best platform?"}],
    temperature=0,
    max_tokens=100,
    )
    ```

  <Tab title="JavaScript">
    ```JavaScript theme={null}
    import OpenAI from 'openai'

    const openai = new OpenAI({
      baseURL: process.env.RUNPOD_HOST,
      apiKey: process.env.RUNPOD_API_KEY,
    })

    const chatCompletion = await openai.chat.completions.create({
       model: "openchat/openchat-3.5-0106",
       messages: [{'role': 'user', 'content': 'Why is Runpod the best platform?'}],

    });
    ```
