# Vision capabilities

For the following example to work, save your [API key](https://docs.tokenfactory.nebius.com/api-reference/introduction#authentication) to the `NEBIUS_API_KEY` environment variable.

You can pass images in the following ways:

* A URL to the image.
* A base64 encoded image directly in the request.

  client = OpenAI(
