LTX 2.3 All-in-One Video Generator

A Gradio app for LTX-2.3 wrapping all six modes of the official ComfyUI All-In-One workflow under a single, focused UI. Runs locally on Apple Silicon (MPS) or NVIDIA (CUDA), and deploys to Hugging Face Spaces (ZeroGPU).

Modes

1. Text → Video (+ optional Audio)
2. Audio → Video (Text + Audio → Video + Audio)
3. Image → Video (+ optional Audio)
4. Lipsync (Image + Audio → Video + Audio)
5. First / Last Frame → Video (keyframe interpolation)
6. Style Transfer (Video → Video, motion control)

Local quickstart

Requires Python 3.11, ~80 GB free disk for model weights, and ~24 GB+ GPU memory (CUDA) or 32 GB+ unified memory (Apple Silicon).

git clone --recurse-submodules https://github.com/<your-handle>/ltx2.3-AIO-generator
cd ltx2.3-AIO-generator
bash setup.sh
source .venv/bin/activate
python app.py

The first run downloads 70 GB of models into your existing `/.cache/huggingface/hub(no duplicate copies in this repo) and symlinks them intocomfyui/models/`.

HF Spaces deployment

This repo is a Gradio Space. The required Pro tier provides ~50 GB persistent /data storage and longer per-call ZeroGPU budgets needed for Balanced and Quality presets.

git remote add space https://huggingface.co/spaces/<your-handle>/ltx2.3-aio
git push space main
