LTX Video 2.3 is an open-source AI video generation model built by Lightricks, the Israeli AI company behind LTX Studio and Facetune. It turns text prompts and images into video — and it does it faster than almost any other model available today.
Most AI video tools make you wait minutes per clip. LTX Video 2.3 generates in seconds. That speed changes everything about how you work.
Who Built LTX Video 2.3
Lightricks released LTX-Video as an open-source project in late 2024, making the full model weights available on Hugging Face. Version 2.3 is the current iteration, built on a Diffusion Transformer (DiT) architecture — the same class powering today's leading AI video models.
The open-source release was intentional. Lightricks wanted developers, filmmakers, and researchers to run, fine-tune, and build on LTX-Video freely — without per-generation fees or platform lock-in.
What LTX Video 2.3 Can Do
Text-to-video is the core use case. Describe a scene and the model generates a video clip at up to 1216×704 resolution, 24fps. The more specific your prompt — camera movement, subject action, lighting — the better the output.
Image-to-video takes a still photo and animates it. Portrait photos, product shots, concept art — feed in a reference image, describe what happens next, and the model fills in the motion. Results are smooth and temporally consistent.
Speed. LTX Video 2.3 is one of the fastest open-source video models in existence. A 5-second clip generates in under 10 seconds on capable hardware. This means more iterations per session, faster creative cycles, and better final output.
Physics and motion quality. The DiT architecture gives LTX 2.3 strong spatial coherence — cloth movement, liquid, and human body mechanics behave realistically. Scenes feel grounded in a way that older generation models don't.
Open architecture. Because LTX Video 2.3 is fully open-source, the community continuously builds on it — custom LoRA fine-tunes, ComfyUI workflows, style adaptations. The ecosystem grows every week.
Why LTX Video 2.3 Stands Out
Speed and quality usually trade off in AI video. LTX Video 2.3 breaks that pattern. You get realistic motion, solid physics, and high temporal consistency — without waiting minutes per generation.
The open-source model is free to run locally if you have a capable GPU. But most people don't want to manage model weights, VRAM requirements, and dependency installations just to generate a clip.
That's where LTX-23 comes in.
Try LTX Video 2.3 Without Any Setup
LTX-23 runs LTX Video 2.3 in the cloud — no installation, no GPU required, no technical setup. Open the browser, type a prompt, get your video.
Credits on LTX-23 never expire. There's no monthly subscription, no reset date, and no credits silently disappearing at the end of the billing cycle. You buy what you need and use it whenever you want.
For anyone who wants fast, high-quality AI video without the overhead of local model management or subscription billing, LTX-23 is the simplest way to get started.
Who LTX Video 2.3 Is For
LTX Video 2.3 is a strong fit for content creators who generate high volumes of clips, filmmakers who need fast iteration, developers building video workflows, and anyone experimenting with AI animation.
