## Overview

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

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

Lite runs at a lower resolution than the standard LemonSlice model (368 x 240). In exchange, it offers a significantly lower price per minute, making it a strong fit for high-volume consumer products where at-scale costs matter most.

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

## Examples

The Lite model excels at rendering avatars of any style - photorealistic, 3D pixar-style cartoons, and 2D cartoons like manga.

## Usage

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

<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 close-up portraits of the face and upper shoulders for photorealistic inputs
* Minimize deadspace above the character's head
* Try using an image that zooms in more on the character if artifacts are present

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