Momentum
LTX-2.5 is an Open-Weights audio-video foundation model from Lightricks (LTX) based on a 22-billion-parameter Diffusion Transformer that generates video and audio together in a single pass. It supports native multi-shot generation with consistent characters, scenes, and voices across multiple shots, as well as 4K-HDR output and automatic clip length determination. The model can be run locally on your own hardware, Fine-Tuned, and accessed via ComfyUI, Hugging Face, or the LTX API.
