AnimTOON: Token-Efficient Vector Animation Generation

AnimTOON is an innovative approach to creating Lottie animations with a focus on minimal token usage, utilizing an AI model that animates SVG files efficiently. With AnimTOON, generating high-quality animations requires 3-4x fewer tokens compared to OmniLottie (as reported at CVPR 2026), enabling smooth animations even on consumer hardware. This model operates with just 5GB of VRAM, making it accessible for individual creators and developers alike.

Key Features

• Versatile Animation Support: The current version (v3) introduces character animation capabilities, specifically coordinated 14-layer walk and idle cycles, trained on skeletal data from Spine and DragonBones.
• Multi-Part SVG Animation: The model can animate individual components of complex SVGs effectively, demonstrated in scenarios such as a 47-part animated crab.
• Human-Readable Format: AnimTOON utilizes a simple text format that allows for easy generation of Lottie animations by describing animation keyframes only, drastically reducing the typical token load.

Comparison with OmniLottie

Example Animation Code:

anim fr=30 dur=120
layer Logo shape
  fill #000000
  path sh x2
  pos [0.5,0.5]
  rot 0.0->-67 0.04->46 0.14->-31 0.28->0 ease=bounce
  scale 0.0->[0,0] 0.14->[90,90] 0.28->[100,100] ease=smooth
  opacity 0.0->0 0.14->100 ease=fade

A complete animation output of only 166 tokens compared to the 18,000+ tokens required by raw Lottie JSON demonstrates AnimTOON's efficiency.

Technical Overview

AnimTOON processes SVG files through a streamlined pipeline:

+--------+     +---------+     +-----------+     +--------+
|  SVG   | --> | Prompt  | --> | AnimTOON  | --> |.lottie |
|  File  |     | Builder |     |  Model    |     |  File  |
+--------+     +---------+     +-----------+     +--------+

With this setup, the model generates animation instructions separately while relying on the provided SVG for shape accuracy, achieving significant token reduction (up to 98.8%).
