About LTX-Desktop

LTX Desktop is a desktop app for making video with LTX models. You can run it locally on a supported NVIDIA GPU or Apple Silicon Mac. If your machine isn't supported, it falls back to the paid LTX cloud API. It's in beta, so expect breaking changes.

Best for: Anyone with a 16GB+ VRAM NVIDIA GPU or a 15GB+ free-RAM Apple Silicon Mac who wants a GUI instead of a ComfyUI graph.

• Generates video from text, images or audio
• Edits video with Retake (regenerating part of a clip)
• Keeps your edits in video editing projects
• Makes and edits images, including image-to-image
• Runs LTX 2.5 Fast locally by default; switch to 2.3 Fast in Settings
• Adds LoRA (small add-on models) and IC-LoRA styles from a built-in library
