Description

Most AI video tools hand you a black box: closed weights, a subscription, and no way to see what is happening under the hood. LTX takes the opposite approach. Built by Lightricks, LTX is an open foundation model that generates and simulates across video, audio, and the physical world, and it puts the weights, the code, and the control in your hands. At the center of the model is LTX-2.5, a 22B-parameter dual-stream diffusion transformer that produces native 4K video at up to 50 frames per second, with audio and video generated together in a single pass rather than stitched together afterward. Artificial Analysis, an independent benchmarking group, currently ranks LTX among the top three AI video models in the world. You choose how you want to use it. Download the open weights and run LTX-2.5 on your own hardware. License the model for on-premise deployment backed by enterprise support. Or build directly on LTX Studio, the production suite that turns the model into a full creative workflow. Companies like ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA already rely on LTX for their own work. LTX is not built for one-off social clips. It is infrastructure for teams that generate motion, audio, and physical environments as part of their own products and pipelines.

Description

NVIDIA Nemotron 3.5 Super VL is a multimodal foundation model developed for AI agents that require reasoning, visual understanding, coding, and multistep task execution. Its 120-billion-parameter mixture-of-experts architecture activates approximately 12 billion parameters per token, enabling efficient inference while maintaining substantial model capacity. The model processes text, images, documents, and video within a unified system that combines multimodal interpretation with instruction following and tool use. Its document intelligence capabilities include extracting information from tables, analyzing charts, interpreting page layouts, and processing multipage documents. Video understanding features support visual information retrieval, content review, incident analysis, and reasoning across recorded sequences. The model also supports software engineering tasks such as code analysis, error identification, debugging, testing, and recommending fixes. Developers can customize Nemotron 3.5 Super VL using NVIDIA NeMo for supervised fine-tuning, low-rank adaptation, and reinforcement learning with domain-specific data. Its inference optimizations include speculative decoding, context reuse, multi-token prediction, and NVFP4 quantization to improve throughput and reduce computational requirements. The model is available with open weights and supports deployment across compatible local hardware, enterprise data centers, and cloud infrastructure.

Product Features

AI Video Editors

LTX is not your typical video editing software that follows a timeline format. Instead, it serves as a foundational model for generative video editing applications. The latest version, LTX-2.5, comes with a desktop application that allows for complete local inference. Its advanced reframing capability enables users to expand video beyond its initial frame while maintaining the integrity of composition, motion, and visual elements, making it an excellent addition to any editing process. If you're in search of a conventional cut-and-trim editing tool, LTX won't meet those needs. However, if you're interested in incorporating AI-generated visuals, audio, or reframing into your own editing workflow using your own hardware, LTX-2.5 provides the open model necessary for that development.

AI Video Generators

The LTX-2.5 is capable of producing native 4K video at rates of up to 50 frames per second, seamlessly integrating audio and video in a single pass instead of combining them afterward. This model is constructed on a dual-stream diffusion transformer featuring 22 billion parameters, allowing for bidirectional cross-attention between audio and video channels. 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 open weights for local execution, obtain a license for on-premise deployment with enterprise-level assistance, or utilize LTX Studio, a comprehensive production suite tailored for creative teams. Esteemed organizations such as ElevenLabs, Asteria Film Co., Magnopus, and NVIDIA are currently utilizing LTX for their video generation needs. This model is specifically designed for AI teams creating dynamic animations and realistic environments within their workflows, rather than for casual social media clips.

Artificial Intelligence

LTX is a pioneering open foundation model designed for video, audio, and world simulation, developed by Lightricks. The latest version, LTX-2.5, boasts a remarkable 22 billion parameters and features a dual-stream diffusion transformer that allows for the creation of synchronized audio and video in a single processing step, achieving native 4K resolution at a rate of up to 50 frames per second. Independent evaluations by Artificial Analysis have placed LTX among the top three AI models worldwide for video generation. In contrast to proprietary AI systems, LTX provides open weights, enabling users to download, examine, customize, and operate the model on their own equipment without vendor lock-in or per-generation fees. This flexibility makes LTX a valuable tool for enterprises, researchers, developers, and production studios, facilitating the integration of video, audio, and simulation functionalities into a diverse array of applications, ranging from entertainment and gaming to robotics and physical AI.
