Introduction of UltraWanComfy
Model Details of UltraWanComfy
UltraWan LoRA — ComfyUI Conversion (Unofficial)
This lora only works with the T2V 1.3b model, it does not work with the 14b. The 4k model has some problems, but the 1k model works well.
This repository contains
converted LoRA weights
from the official
APRIL-AIGC/UltraWan
release.
The only modification made was converting the
.ckpt
/ original format into
.safetensors
compatible with
ComfyUI
.
No training, fine-tuning, or architecture changes were performed.
📌 What This Is
- ✅ Direct conversion of original UltraWan LoRA weights to ComfyUI-compatible safetensors format
- ❌ Not trained, modified, or altered in any way beyond the format change
- 🎯 For users who want to test UltraWan LoRA with ComfyUI’s Text-to-Video pipelines
