Lynx is a state-of-the-art high-fidelity personalized video generation model that creates videos from a single input image while preserving the subject's identity. Built on a Diffusion Transformer (DiT) foundation model with lightweight ID-adapters and Ref-adapters for identity preservation and spatial detail enhancement.
## Model Variants
This repository contains two model variants:
- **Lynx Full Model** (`lynx_full`): Complete version with all advanced features and best performance
- **Lynx Lite Model** (`lynx_lite`): Lightweight model with fewer parameters (no Ref-adapter), tailored for efficient 24fps (121-frame) video generation.
