# Vercel v0

> Use Vercel v0 models for web development with Agno agents.

The Vercel v0 API provides large language models, designed for building modern web applications. It supports text and image inputs, provides fast streaming responses, and is compatible with the OpenAI Chat Completions API format. It is optimized for frontend and full-stack web development code generation.

For more details, refer to the [official Vercel v0 API documentation](https://vercel.com/docs/v0/api).

## Authentication

Set your `V0_API_KEY` environment variable. You can create an API key on [v0.dev](https://v0.dev/chat/settings/keys).

<CodeGroup>
  ```bash Mac theme={null}
  export V0_API_KEY=your-v0-api-key
  ```

  ```bash Windows theme={null}
  setx V0_API_KEY your-v0-api-key
  ```
</CodeGroup>

## Example

Use `V0` with your `Agent`. The following example assumes you have the `V0` Python class (as you provided) located at `agno/models/vercel.py`.

<CodeGroup>
  ```python agent.py theme={null}
  from agno.agent import Agent
  from agno.models.vercel import V0

  agent = Agent(
      model=V0(id="v0-1.0-md"),
      markdown=True
  )

  # Print the response in the terminal
  agent.print_response("Create a simple web app that displays a random number between 1 and 100.")

  # agent.print_response("Create a webapp to fetch the weather of a city and display humidity, temperature, and wind speed in cards, use shadcn components and tailwind css")

  ```
