FAQs

What is LTX Desktop?

LTX Desktop is an open-source, AI-powered video production suite currently in beta that runs entirely on your machine. It combines a full non-linear editor with on-device AI generation - including text-to-video, image-to-video, audio-to-video, retake, image generation, and timeline import from professional NLEs. Everything runs locally, powered by the LTX-2.3 engine. No internet connection is required after installation.

Is it free?

Yes, if you have a machine capable of running the LTX-2 model locally, there are zero costs for inference. LTX Desktop is free and open source, licensed under Apache 2.0. The app is our way of showing what's possible with LTX-2.3 and giving the community something to build on.

If you don’t meet the hardware requirements for local inference, or prefer to run inference via Lightricks’ API, you can enable LTX API inference in the Settings panel.

Note: the underlying LTX-2.3 model weights are subject to the LTX-Video Model License,

What can LTX Desktop do?

Gen Space — AI generation

• Fully customizable keyboard shortcuts
• Keyboard preset layouts for Premiere, DaVinci Resolve, and Avid

What are the recommended system requirements to run LTX Desktop locally?

Does LTX Desktop run on Mac?

Yes. LTX Desktop is supported on Apple Silicon Macs (M1 and later). Currently, generation on macOS runs via the LTX API rather than locally on the GPU. Support for local GPU inference on macOS is planned for a future release.
