About

LTX-2.3 is an advanced AI video generation model designed to create high-quality videos from text prompts, images, or other media inputs while maintaining strong control over motion, structure, and audiovisual synchronization. It is part of the LTX family of multimodal generative models built for developers and production teams that need scalable tools to generate and edit video programmatically. It builds on the capabilities of earlier LTX models by improving detail rendering, motion consistency, prompt understanding, and audio quality throughout the video generation pipeline. It features a redesigned latent representation using an upgraded VAE trained on higher-quality datasets, which improves the preservation of fine textures, edges, and small visual elements such as hair, text, and intricate surfaces across frames.

About

This model is based on a multi-stage text-to-video generation diffusion model, which inputs a description text and returns a video that matches the text description. Only English input is supported. This model is based on a multi-stage text-to-video generation diffusion model, which inputs a description text and returns a video that matches the text description. Only English input is supported. The text-to-video generation diffusion model consists of three sub-networks: text feature extraction, text feature-to-video latent space diffusion model, and video latent space to video visual space. The overall model parameters are about 1.7 billion. Support English input. The diffusion model adopts the Unet3D structure, and realizes the function of video generation through the iterative denoising process from the pure Gaussian noise video.
