## Overview

LemonSlice Lite is specifically designed for the needs of consumer apps:

* Low-cost
* High volume
* Ultra-low latency
* Instant character creation from 1 photo

Lite is a less powerful avatar model. In exchange, it offers a significantly lower price per minute (as low as \$0.039/min), making it a strong fit for high-volume consumer products where at-scale costs matter most.

<Info>
  Lite is only available to enterprise customers. Contact [support@lemonslice.com](mailto:support@lemonslice.com) to get access.

## Examples

Although the Lite model is less capable than the Standard model, it still has great performance in many domains. We recommend using the Lite model with stylized characters (3D-style like in Pixar movies or 2D cartoons, like in manga). If using photorealistic characters, zoom in closely to the face. Here are example outputs of the Lite model:

## Usage

Set the optional `model` parameter to `"lite"` when starting a session. Supported `aspect_ratio` values are `"2x3"` and `"1x1"`. The Lite model is lower resolution.

<CodeGroup>
  ```python LiveKit (Python) theme={null}
  avatar = lemonslice.AvatarSession(
      agent_image_url="...",
      model="lite",
      aspect_ratio="2x3",
  )
  ```

  ```javascript LiveKit (Node.js) theme={null}
  const avatar = new lemonslice.AvatarSession({
    agentImageUrl: "...",
    extraPayload: { model: "lite", aspectRatio: "2x3" },
  });
  ```

  ```python Pipecat (Python) theme={null}
  transport = LemonSliceTransport(
      ...
      session_request=LemonSliceNewSessionRequest(
          agent_image_url="...",
          model="lite",
          aspect_ratio="2x3",
      ),
  )
  ```
</CodeGroup>

## Framing and image tips

For best results when using Lite:

* Use a stylized image, such as 3D cartoon, anime style, ghibli, etc.
* If using a photorealistic image, use tight face crops
* Minimize deadspace above the character's head

See [Avatar Image Tips](/docs/prompting-guide/avatar-image-tips) for general guidance on reference images.
