Ltx2.3

Ltx2.3 is a groundbreaking, open-source AI video generation model that empowers teams to create together. It transforms simple text descriptions, images, audio tracks, or existing videos into high-quality, cinematic content with remarkable speed and fidelity. Built on a powerful 22-billion-parameter Diffusion Transformer (DiT) architecture, it's designed for a collaborative environment where content creators, marketing teams, and businesses can work in synergy to produce professional videos without the traditional barriers of cost, time, or technical expertise. The core value proposition of Ltx2.3 lies in its unified, multi-modal platform that accelerates the creative workflow. By offering intuitive controls for motion synthesis, aspect ratio selection, and quality settings, it allows team members from different disciplines—writers, designers, social media managers—to contribute seamlessly to the video production process. Whether you're generating b-roll to complement a narrative, animating mockups for a client presentation, or producing scalable content for campaigns, Ltx2.3 acts as a powerful collaborative partner, turning collective ideas into engaging visual stories faster than ever before.

Multi-Modal Generation Pipeline

Ltx2.3 serves as a unified creative hub for teams, supporting multiple input methods to kickstart the video creation process. Team members can collaborate by feeding the model text prompts, uploading reference images, providing audio for synchronization, or using existing video clips. This flexibility ensures that whether your starting point is a script, a storyboard sketch, a voiceover, or a previous project, the entire team can build upon it together to generate cohesive and dynamic video content efficiently.

22B Parameter DiT Engine for Speed & Quality

The model's robust 22-billion-parameter Diffusion Transformer engine is a game-changer for team productivity. It runs up to 18 times faster than comparable models, meaning your team spends less time waiting for renders and more time iterating and refining ideas. This architectural powerhouse delivers superior output with sharper textures, finer details, and more accurate lighting, ensuring the final product meets professional standards and reflects well on the collective effort of the team.

Face & Character Preservation

Maintaining consistency is crucial for collaborative storytelling, and Ltx2.3 excels in this area. Its advanced face and character preservation ensures that subjects retain their appearance, expressions, and proportions across all frames of a generated video. This feature allows teams to work on multi-shot sequences or character-driven content with confidence, knowing that their creative vision will remain coherent and polished from start to finish.

Native Portrait Video & Open-Source Access

Ltx2.3 is built for the modern content ecosystem, offering native vertical video generation at 1080x1920 resolution, perfectly tailored for social media platforms like Reels, Shorts, and TikTok. Furthermore, its open-source nature fosters a spirit of community and shared innovation. Teams can access the model weights freely for commercial use under certain conditions, enabling developers and creators to experiment, customize, and integrate the technology into their own collaborative workflows.

Marketing & Social Media Content Creation

Marketing teams can collaborate to rapidly produce high-volume, platform-specific video content. From animated product demos and promotional clips to engaging social media shorts, Ltx2.3 allows copywriters, strategists, and designers to work in tandem, transforming campaign ideas into polished videos quickly and cost-effectively, ensuring consistent brand messaging across all channels.

Prototyping & Product Demonstrations

Design and product teams can use the image-to-video feature to bring static mockups and UI designs to life. By uploading an app screenshot or product image, they can collaboratively generate animated walkthroughs and demo videos that clearly communicate functionality and user experience to stakeholders, clients, or for use in crowdfunding campaigns.

Filmmaking & Creative Storytelling

Independent filmmakers and creative studios can use Ltx2.3 as a collaborative pre-visualization and asset generation tool. Directors and writers can generate cinematic b-roll, conceptual scenes, or establish shots based on text descriptions, allowing the entire production team to align on visual style and narrative flow before expensive live shooting begins.

Educational & Explainer Video Production

Educators, trainers, and content teams can work together to create engaging explainer videos and educational materials. By inputting a script or audio lecture, they can generate synchronized visual content that enhances comprehension. This collaborative approach simplifies the production of complex animated concepts, making knowledge sharing more dynamic and accessible.

What types of input does Ltx2.3 accept?

Ltx2.3 is designed for collaborative flexibility, accepting multiple input modalities to suit different team members' strengths. You can generate video from a text description, an uploaded image, an audio track for synchronized video, or an existing video clip to apply new styles or motions, making it a versatile tool for any creative workflow.

How fast is Ltx2.3 compared to other models?

Ltx2.3 is engineered for team efficiency, operating at groundbreaking speeds. It is built to run approximately 18 times faster than models like WAN 2.2 on equivalent H100 GPUs. This means your team can generate high-quality video drafts and iterations in a fraction of the time, significantly accelerating project timelines.

Is Ltx2.3 really free to use for commercial projects?

Yes, in a move that supports collaborative innovation, the LTX 2.3 model weights are open-source and available on Hugging Face. They are free for both personal and commercial use for entities with under $10 million in annual revenue. This allows small businesses and startup teams to leverage cutting-edge AI video technology without upfront licensing costs.

Can Ltx2.3 create videos for social media platforms like TikTok?

Absolutely. Ltx2.3 is built with modern content teams in mind, featuring native support for vertical portrait video at 1080x1920 resolution. It is specifically trained on real portrait data, not cropped landscape footage, making it an ideal collaborative tool for creating optimized, high-quality content for TikTok, Instagram Reels, and YouTube Shorts.
