WAN 2.1 LoRA — `tvix`

A personalized LoRA (Low-Rank Adaptation) trained on WAN 2.1 14B for generating video content with a specific identity. Works with both Image-to-Video and Text-to-Video WAN 2.1 pipelines.

Trained using dual-mode Musubi Tuner (high + low noise models → single LoRA file).

Architecture

This is a dual-mode LoRA trained with --timestep_boundary 875:

High-noise model (timesteps > 875): Handles initial structure and motion
Low-noise model (timesteps ≤ 875): Handles fine details and identity

Both models are trained simultaneously and packed into a single .safetensors file. Compatible with any WAN 2.1 workflow that supports LoRA.
