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.

Wan2.2-Animate
Wan2.2 Animate is a dedicated component of the Wan video generation suite, which focuses on producing high-quality character animations and facilitating character swaps in videos. This module empowers users to convert still images into lively videos or change subjects in pre-existing clips while ensuring that realism and motion continuity are upheld. It operates by utilizing two main inputs: a reference image that illustrates the character's look and a reference video that conveys the necessary motion, expressions, and context of the scene. By combining these elements, it can effectively bring a static character to life by mirroring the body movements, gestures, and facial expressions from the provided video or replace an existing character while keeping the original lighting, camera dynamics, and surrounding environment intact for a fluid transition. The technology employs sophisticated methodologies, including spatially aligned skeleton signals and implicit facial feature extraction, to faithfully capture and reproduce the nuances of movement and expression. Moreover, the module's innovative design allows for a wide range of creative applications in filmmaking and animation, making it a valuable tool for content creators.

Hunyuan Motion 1.0
Hunyuan Motion, often referred to as HY-Motion 1.0, represents an advanced AI model designed for transforming text into 3D motion, utilizing a billion-parameter Diffusion Transformer combined with flow matching techniques to create high-quality, skeleton-based animations in mere seconds. This innovative system comprehends detailed descriptions in both English and Chinese, allowing it to generate fluid and realistic motion sequences that can easily integrate into typical 3D animation workflows by exporting into formats like SMPL, SMPLH, FBX, or BVH, which are compatible with software such as Blender, Unity, Unreal Engine, and Maya. Its sophisticated training approach includes a three-phase pipeline: extensive pre-training on thousands of hours of motion data, meticulous fine-tuning on selected sequences, and reinforcement learning informed by human feedback, all of which significantly boost its capacity to interpret intricate commands and produce motion that is not only realistic but also temporally coherent. This model stands out for its ability to adapt to various animation styles and requirements, making it a versatile tool for creators in the gaming and film industries.
