Summary

LTX Desktop is an open-source desktop application for generating videos using LTX models. It targets users needing local generation on supported hardware or a flexible API fallback, offering AI-driven video creation with local processing benefits.

How It Works

The app uses a three-tier architecture: a React/TypeScript frontend, an Electron main process for OS integration, and a Python/FastAPI backend for model management and GPU execution. It supports local generation on Windows with NVIDIA GPUs (≥32GB VRAM) for privacy and performance, and an API-only mode for macOS and less capable Windows hardware, requiring an LTX API key. An optional local text encoder enables fully offline operation on supported Windows systems.

Quick Start & Requirements

Install via GitHub Releases. Windows local generation requires Windows 10/11 (x64), an NVIDIA GPU with CUDA and ≥32GB VRAM, and 16GB+ RAM (32GB recommended). API-only modes (macOS, unsupported Windows) need macOS 13+ (Apple Silicon) or Windows, plus internet. Development requires Node.js, uv, Python 3.12+, and Git. First-run setup involves accepting model licenses. An LTX API key is mandatory for API-only modes and optional for local mode if the local text encoder is enabled.
