LTX 2.3 is an open-source video generation model created by Lightricks. It's built on a Diffusion Transformer (DiT) architecture and can produce synchronized video and audio from text prompts, images, or audio inputs. The model supports resolutions up to 4K, frame rates up to 50 FPS, and clips up to 20 seconds long. Our platform provides a web-based interface for LTX 2.3 so you can generate videos without installing software or managing GPU hardware.
No — we're a third-party platform that provides access to the LTX 2.3 model through an easy-to-use web interface. LTX 2.3 is an open-source model released by Lightricks with weights available on HuggingFace. We run the model on our infrastructure so you can focus on creating instead of setting up hardware.
Yes — you can try LTX 2.3 on our platform for free. We offer a free tier that lets you generate videos and experience the model's capabilities at no cost. For higher-volume usage, faster rendering, and 4K output, we have paid plans available.
LTX 2.3 includes a redesigned VAE for sharper fine details and cleaner edges, a 4x larger text connector for better prompt adherence, native 9:16 portrait video support (trained on vertical data, not cropped), cleaner audio with a new vocoder and filtered training data, and stronger image-to-video output with less freezing and more natural motion.
LTX 2.3 is versatile — it handles product demos, social media clips, cinematic scenes, nature footage, abstract art, educational animations, and more. It supports text-to-video, image-to-video, and audio-to-video workflows, plus extend-video for longer sequences. You can generate in landscape, portrait, or square formats.
Yes. LTX 2.3 generates synchronized audio alongside video in a single pass. This includes ambient sounds, sound effects, dialogue, and music that match the on-screen action. The audio quality in version 2.3 is significantly cleaner than previous versions, thanks to a new vocoder and filtered training data.
Absolutely. Our web-based LTX 2.3 video generator works on any modern smartphone or tablet browser. Enter your prompt, pick your settings, and generate — no app installation needed. The native portrait support makes LTX 2.3 especially convenient for creating mobile-first content.
LTX 2.3 can generate video at 1080p, 1440p, and up to 4K (3840×2160). Supported frame rates include 24, 25, 48, and 50 FPS. You can also choose native portrait mode (1080×1920) for vertical video that's properly composed — not cropped from a wider frame.
A single LTX 2.3 generation can produce clips up to 20 seconds long. If you need something longer, the extend-video feature lets you continue a clip beyond that limit while maintaining visual and audio consistency.
LTX 2.3 is released under an open license. Videos you generate through our platform are yours to use for social media, marketing, client projects, and other commercial purposes. Check the specific license terms on the Lightricks GitHub for full details on model usage.
LTX 2.3 is a powerful and modern AI tool that significantly advances the field of Video Generation by combining open-source accessibility with professional-grade performance. Built on a Diffusion Transformer (DiT) architecture by Lightricks, it enables users to generate synchronized video and audio directly from text prompts, images, or audio inputs. With support for up to 4K resolution, 50 FPS frame rates, and clips up to 20 seconds long, LTX 2.3 delivers high-fidelity output that meets the demands of both creative experimentation and production workflows.
One of the most impressive aspects of this AI tool is its accessibility. As a web-based platform, it removes the need for local installation, GPU management, or technical setup. Users can simply access LTX 2.3 through a browser interface and immediately begin generating videos. This makes it an ideal solution for creators who want to focus on storytelling and design rather than infrastructure. Additionally, the availability of a free tier lowers the entry barrier, allowing users to explore its Video Generation capabilities before committing to higher-tier plans.
From a technical standpoint, LTX 2.3 introduces several key improvements over previous versions. The redesigned VAE produces sharper details and cleaner edges, while the expanded text connector enhances prompt adherence, ensuring more accurate translation of user intent into visual output. Native 9:16 portrait support is another major upgrade, making this AI tool especially effective for mobile-first content creation on platforms like TikTok and Instagram. Combined with improved image-to-video performance and reduced motion artifacts, LTX 2.3 delivers smoother and more realistic animations.
Another standout feature is its synchronized audio generation, which produces ambient sounds, music, dialogue, and effects in a single pass. This integration significantly reduces post-production effort and makes LTX 2.3 a complete Video Generation solution rather than just a visual tool. Whether used for product demos, cinematic storytelling, educational content, or social media clips, the system supports a wide range of creative applications.
LTX 2.3 also excels in flexibility. It supports multiple workflows including text-to-video, image-to-video, and audio-driven generation, along with extend-video functionality for longer sequences. Users can choose between different resolutions and frame rates, ensuring adaptability for both fast iteration and high-quality output. Its compatibility with mobile devices further enhances its usability, enabling creators to generate videos anytime, anywhere.
Overall, LTX 2.3 stands out as a next-generation AI tool that redefines Video Generation through a combination of accessibility, performance, and versatility. With its open-source foundation, commercial usage rights, and advanced generative capabilities, it empowers creators, marketers, and developers to produce high-quality video content efficiently and at scale.
