Lightricks open-sources LTX-2, the production-ready audio and video generation model

Lightricks announced the open-source release of LTX-2, the production-ready model to combine open audio and video generation with native 4K output, synchronized expressive sound, and full access to model weights, inference, and training code, alongside extensive options for fine-tuning and deeper customization for builders and creative professionals.

The model is free to use for academic research and for commercial use for companies with less than $10M in annual recurring revenue (ARR). Organizations above this threshold are required to obtain a commercial license that enables continued use of the same open-weight model in production, along with options for enterprise-grade support, deployment flexibility, and customization. LTX-2 is also available through a self-serve API on the website and is also accessible directly within the LTX platform, with integrations through Fal, Replicate, ComfyUI, OpenArt, and others.

“LTX-2 is the first truly open audio-video model, released with open weights and training code, and designed to run locally on consumer GPUs,” said Zeev Farbman, Co-founder and CEO of Lightricks. “It delivers the kind of quality and performance teams usually associate with closed systems, without giving up control, transparency, or the ability to customize. We believe this release marks a meaningful shift for both research and real-world production pipelines, expanding what teams can build and who gets to build it.”

LTX-2 is capable of generating synchronized video and audio up to 20 seconds long, rendered at native 4K resolution and 50 frames per second, while maintaining expressive lip sync and audio fidelity. The release includes both the full model and a distilled variant designed for significantly faster inference with minimal quality trade-offs, giving teams direct control over the balance between performance and fidelity based on their hardware and use case. Providing a production-grade distilled model out of the box removes a costly and complex step for developers and enables broader deployment across a wider range of systems. Support for Comfy pipelines is included to accelerate integration and experimentation.
