LTX Desktop
Open-source AI video production suite running locally on your GPU
About LTX Desktop
LTX Desktop is a free, open-source AI video production suite by Lightricks that runs entirely on your machine. It combines a professional non-linear editor with on-device AI generation including text-to-video, image-to-video, audio-to-video, retake, and context-aware gap fill powered by the LTX-2.3 model (20.9B parameters).
Pros & Cons
Pros
- Completely free with no per-generation costs — pay for hardware once
- Full privacy: all processing runs locally with no cloud dependency
- Professional NLE interoperability with Premiere Pro, DaVinci Resolve, and Final Cut Pro
- Open source under Apache 2.0 with active community development
- High-quality output with 20.9B parameter model and local upscaling to 1080p
Cons
- Requires NVIDIA GPU with 32GB VRAM and 160GB disk space for full model library
- macOS users must use the LTX API instead of local generation
- Currently in beta — expect breaking changes
- Large initial model download (~150GB) before first use
- Steeper setup compared to cloud-based AI video tools
