Practical overview

When it fits

Use Ltx Desktop when you want an LTX-based generation and editing workflow in a desktop app, and can meet the local hardware requirements or use API mode.

Who it is for

  • Creators who want to generate video from text prompts, images or audio in a desktop application.
  • Users with supported NVIDIA or Apple Silicon hardware who want local generation.
  • Users whose hardware does not support local generation and who can use the app's API mode.

Documented uses

  • Generate video from a text prompt, image or audio input.
  • Make video edits such as Retake or Extend using supported model and generation modes.
  • Use local LoRAs to steer local video generation toward a style or subject.
  • Generate images from text or edit images.
Before you choose

Requirements & limits

The app is open source under the Apache-2.0 license. API mode is available; API-only Pro models are identified as paid cloud generation. Local use requires model downloads, and gated LTX 2.5 weights may require Hugging Face sign-in and license acceptance.

  • Local generation requires at least 15 GiB VRAM on Windows or Linux with CUDA, or 32 GiB total RAM on Apple Silicon; Intel Macs do not support local generation.
  • The LTX 2.5 Fast core pack needs about 72 GB of free disk space, and broader model installs need more.
  • LTX 2.5 Fast is the default local model; LTX 2.3 Fast retains local Retake and Extend support.
  • LTX 2.5 Pro and LTX 2.3 Pro are API-only; API Pro generation is paid cloud generation.
  • LoRAs apply to local generation, not API mode.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Ltx Desktop and complete first-run setup

Install the desktop app and prepare it to download LTX model weights.

Before you start

  • A Windows, Linux or macOS desktop.
  • Internet access.
  • For gated LTX 2.5 weights, Hugging Face sign-in and acceptance of the model license may be required.

Steps

  1. Download the latest installer from the project's GitHub Releases page.

  2. Install and launch Ltx Desktop.

  3. Complete the first-run setup; sign in to Hugging Face and accept model terms if prompted to download gated weights.

Expected outcome

The app is installed and first-run setup is complete; model weights can download into its models folder.

Guide limitations

  • Model downloads can be large and take time; the LTX 2.5 Fast core pack requires about 72 GB of free disk space.
  • This setup guide does not cover generating a video.
  • The application is beta software and may have breaking changes.
