Wanxiao 2.1-1.3B-LoRA-Aesthetic-Distillation-v1

Model Introduction

This LoRA model is trained based on the Wanxiao 2.1-1.3B model and the DiffSynth-Studio framework. It has been fine-tuned on an aesthetically curated dataset to enhance the visual appeal of generated videos, and supports disabling classifier-free guidance for faster inference.

Recommended parameter settings:

cfg_scale=1
sigma_shift=10

Note: Using this model may reduce the diversity of generated videos. Adjust the lora_alpha value to control the influence of the LoRA on generation results.

Model Performance

Below are comparisons of model outputs under the settings cfg_scale=1 and sigma_shift=10.

Prompt: A serene tropical beach at sunset, with palm trees, flower-covered rocky cliffs, and gentle waves breaking

Prompt: A robot in a desert world, covered in rust, with dappled sunlight

Usage Instructions

This model is built on the DiffSynth-Studio framework. Please install it first:

pip install diffsynth

python

import torch
from diffsynth import ModelManager, WanVideoPipeline, save_video
from modelscope import snapshot_download

python

snapshot_download(
