LTX-2 Pro

LTX-2 Pro is a high-fidelity video generation model developed by Lightricks, designed for professional creative and production workflows. It is part of the LTX-2 family, serving as an audio-visual foundation model capable of generating synchronized audio and video simultaneously in a single pass. This unified approach ensures that visual motion and sound cues are natively aligned without the need for external post-production layering.

The model is built on a Diffusion Transformer (DiT) architecture and features approximately 19 billion parameters. It supports multiple resolutions, including 1080p, 1440p, and native 4K, with frame rate options of 25 or 50 frames per second. LTX-2 Pro is optimized for visual stability and subject consistency, enabling the creation of detailed sequences up to 20 seconds in length.

Compared to the "Fast" variant of the same family, the Pro model prioritizes cinematic quality and intricate detail for use in advertising, film previsualization, and high-end content creation. Lightricks released the model weights and codebase to the public in early 2026 to support local execution and community customization.
