What is LTX?

LTX builds open world models, AI systems that generate, simulate, and shape video, audio, and the physical world. Lightricks created LTX so that developers, studios, and enterprises can own the model they build on, not just rent access to someone else's. The current release, LTX-2.5, is a 22B-parameter dual-stream diffusion transformer. It renders native 4K footage at up to 50fps and produces synchronized audio and video in one pass, no separate tools required. Independent benchmarks from Artificial Analysis place LTX in the top three AI video models worldwide. There is no single way to work with LTX. Pull the open weights and run the model yourself on your own machines. Take a commercial license for on-premise deployment with full enterprise support. Or use LTX Studio, the packaged production suite for creative teams that want the model without managing the infrastructure. ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA all build on it today. If you need a quick clip for social media, look elsewhere. LTX exists for AI teams turning video, audio, and simulation into part of their own product, not a novelty.

What is LFM3?

LFM3 showcases Liquid AI's collection of versatile, open-weight foundational models tailored for a diverse range of applications, spanning text, vision, audio, and multimodal functionalities. This array includes specialized versions for generating text, processing vision-language tasks, handling audio, addressing omni tasks, and facilitating decision-making processes. Developers can choose to download the model weights for customization through fine-tuning and deploy them on local edge devices, or they may opt for Liquid AI’s hosted API for seamless access. The potential uses for these models are extensive, including conversational agents, invoking tools, transcribing and synthesizing speech, interpreting images and videos, extracting and classifying documents, routing information, and enabling robotics capabilities. LFM3 is designed to meet the needs of developers, researchers, and organizations aiming to build customized AI solutions that prioritize adaptable deployment options, including support for on-premises inference. Additionally, these open-weight models are governed by Liquid AI’s LFM Open License, which stipulates the eligibility for commercial use and its specific terms based on the annual revenue of the organization. This level of flexibility empowers users to precisely customize their AI implementations to suit their specific requirements, thereby significantly enhancing the overall functionality and effectiveness of the models. Moreover, with the rapid advancements in AI, having such adaptable tools is crucial for staying competitive in the ever-evolving technological landscape.

AI Video Editors

LTX is a revolutionary approach to video editing that moves away from conventional timeline-based systems. Instead, it serves as a foundational model for advanced generative video editing applications. With the release of LTX-2.5, users gain access to a desktop application that allows for entirely local processing. One of its standout features is the production-quality reframing tool, which enables users to extend video content beyond its initial borders while maintaining the integrity of composition, motion, and visual elements—ideal for integration within an editing workflow. If your needs revolve around simple cut-and-trim functionality, LTX may not suit you. However, for those interested in incorporating AI-generated visuals, audio, or reframing capabilities into their editing processes using their own hardware, LTX-2.5 offers a versatile open model for development.

AI Video Generators

The LTX-2.5 model is capable of creating authentic 4K video at rates of up to 50 frames per second, merging audio and video in a single streamlined process instead of combining them later. This innovative technology is powered by a 22B-parameter dual-stream diffusion transformer that utilizes bidirectional cross-attention between its audio and video components. According to independent evaluations by Artificial Analysis, LTX is recognized as one of the top three AI video models worldwide. Users have the option to download the open weights for local execution, obtain a license for on-premise installation with enterprise-level support, or utilize LTX Studio, a comprehensive production suite designed for creative teams. Notable companies such as ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA are currently harnessing the capabilities of LTX for their video production needs. This model is specifically engineered for AI teams focused on creating dynamic motion and immersive environments within their own workflows, rather than for producing standalone social media clips.
