LTX 2.3 AI Video Generator

LTX 2.5 is an open-weights audio-video foundation model by Lightricks, offered through a browser-based platform. It generates synchronized video and audio from text, images, or audio tracks, with native multi-shot continuity and output up to 4K. Designed for creators, marketers, and filmmakers, it requires no local setup or GPU. This is an independent third-party service and is not operated by the company behind the model it is built around.

How it works

LTX 2.5 uses a Diffusion Fidelity Rendering pipeline and a new video decoder to preserve detail in faces, text, and fast motion. It generates synchronized audio and video from text, animates first and last frames for image-to-video, or builds visuals around an audio track. Native multi-shot generation keeps characters, environments, lighting, and voice consistent across cuts, and output can be up to 4K.

Key capabilities

Key capabilities include text-to-video, image-to-video, and audio-to-video generation, with native 16:9 and 9:16 aspect ratios. A fine-tuned Gemma 4 12B text encoder and custom prompt enhancer follow complex creative direction from shorter prompts. Fast mode supports clips up to 20 seconds for rapid iteration, while Pro mode offers maximum fidelity. Automatic duration can match clip length to the requested action.

Who it is for

LTX 2.5 is for short-form and social media creators composing in 9:16 for TikTok, Reels, and Shorts, YouTube and long-form producers needing B-roll, educators and course creators illustrating concepts, indie filmmakers and animators exploring connected coverage, and agencies or freelance creatives for concept exploration and client previews. E-commerce and product marketing teams can turn product stills into dynamic reveals.
