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.

Recent progress in text-to-image synthesis has been driven by diffusion models trained on vast collections of image-text pairs. To effectively adapt this approach for 3D synthesis, there is a critical need for large datasets of labeled 3D assets and efficient architectures capable of denoising 3D information, both of which are currently insufficient. This research aims to tackle these obstacles by utilizing an established 2D text-to-image diffusion model to facilitate text-to-3D synthesis. We introduce a groundbreaking loss function based on probability density distillation, enabling a 2D diffusion model to guide the optimization of a parametric image generator effectively. By applying this loss within a DeepDream-inspired framework, we enhance a randomly initialized 3D model, specifically a Neural Radiance Field (NeRF), through gradient descent, ensuring its 2D renderings from various angles demonstrate reduced loss. As a result, the generated 3D representation can be viewed from multiple viewpoints, illuminated under different lighting conditions, or integrated seamlessly into a variety of 3D environments. This innovative approach not only addresses existing limitations but also paves the way for the broader application of 3D modeling in both creative and commercial sectors, potentially transforming industries reliant on visual content.

HunyuanVideo-Avatar
HunyuanVideo-Avatar enables the conversion of avatar images into vibrant, emotion-sensitive videos by simply using audio inputs. This cutting-edge model employs a multimodal diffusion transformer (MM-DiT) architecture, which facilitates the generation of dynamic, emotion-adaptive dialogue videos featuring various characters. It supports a range of avatar styles, including photorealistic, cartoon, 3D-rendered, and anthropomorphic designs, and it can handle different sizes from close-up portraits to full-body figures. Furthermore, it incorporates a character image injection module that ensures character continuity while allowing for fluid movements. The Audio Emotion Module (AEM) captures emotional subtleties from a given image, enabling accurate emotional expression in the resulting video content. Additionally, the Face-Aware Audio Adapter (FAA) separates audio effects across different facial areas through latent-level masking, which allows for independent audio-driven animations in scenarios with multiple characters, thereby enriching the storytelling experience via animated avatars. This all-encompassing framework empowers creators to produce intricately animated tales that not only entertain but also connect deeply with viewers on an emotional level. By merging technology with creative expression, it opens new avenues for animated storytelling that can captivate diverse audiences.
