Overview

LTX-2 is an open-source, next-generation multimodal AI model designed for video with synchronized audio and image creation as a comprehensive solution for creative workflows.

Capable of running on consumer-grade GPUs, it combines high-fidelity visuals, coherent sound, and multi-flow performance modes into a single platform.

LTX-2 has the capability to generate, enhance, and repurpose visuals more efficiently. Unlike most models, it considers sound and visuals in a unified production process for synchronized motion, dialogue, ambience, and music.

The model is designed to work with real production workflows, connecting directly with editing suites, broadcast tools, game engines, and VFX pipelines.

It supports both quick previews and delivery-ready 4K outputs. The model provides creative control through text, image, depth, and reference-video inputs, and offers multi-keyframe conditioning, 3D camera logic, and fine-tuning options.

As an open-source tool, LTX-2 enables researchers, enterprises, and independent creators to customize the model to fit their needs. Its use cases include post-production, pre-production, animation, restoration among others, offering solutions to automate motion tracking, rotoscoping, plate replacement, and other tasks, thereby reducing the time and cost of production while maintaining quality.

The upcoming releases will offer open access to the model's weights and training code. Its flexibility and customization options make it ideal for studios, research teams, and solo developers.
