LTX-2 19B is an open-source video generation model developed by Lightricks and released on January 6, 2026. It uses an asymmetric dual-stream Diffusion Transformer architecture to generate video and synchronized audio together in a single unified process, rather than producing silent video and adding audio as a separate step. The model accepts text prompts, reference images, or existing video clips as input and outputs native 4K video with flexible frame-rate control and support for extended clip durations.

LTX-2.3 is a multimodal video generation model developed by Lightricks and released in March 2026. Built on a Diffusion Transformer architecture with 22 billion parameters, it generates synchronized audio and video in a single forward pass at resolutions up to 4K at 50 frames per second, for clips up to 20 seconds long. It is available as open-source software with open weights under a permissive license, and can be run locally, accessed via API, or deployed on-premises.

LTX-2.3 LoRA is a Low-Rank Adaptation fine-tuning system built on top of Lightricks' LTX-2.3 video generation model, released in January 2026. Rather than retraining the full model, LoRA adapters allow users to teach the base model new characters, visual styles, or motion behaviors at a fraction of the computational cost. The system supports both text-to-video and image-to-video generation workflows, and LoRAs trained on the earlier LTX-2.0 model are reported to retain compatibility with the 2.3 update.

Handles both text and image inputs for content generation and problem-solving.
