# Nano Banana

> Generate and edit images with the Nano Banana model family.

Nano Banana is the first image model family documented for the YingTu unified
task flow. Use it for prompt-based generation and image-guided editing.

<Info>
  The public model ID is part of the request contract. Do not invent aliases in
  client code; select an ID from the verified model catalog.

## Typical workflow

<CardGroup cols={2}>
  <Card title="Choose parameters" icon="sliders-horizontal" href="/en/models/image/nano-banana/parameters">
    Set the prompt, aspect ratio, and supported output resolution.
  </Card>

  <Card title="Copy an example" icon="code-2" href="/en/models/image/nano-banana/examples">
    Start from cURL, Python, or Node.js.
  </Card>
</CardGroup>

The examples use `gemini-3.1-flash-image` as the model ID and the common task
envelope.
