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.

Odyssey
Odyssey-2 represents a cutting-edge interactive video technology that allows for immediate and real-time video generation that users can engage with. Simply enter a prompt, and the system promptly starts streaming several minutes of video that reacts to your input. This innovation transforms video from a traditional playback experience into a responsive, action-sensitive stream: the model operates in a causal and autoregressive manner, crafting each frame based on previous frames and your actions instead of adhering to a set timeline, which enables a seamless adaptation of camera perspectives, environments, characters, and narratives. The platform efficiently begins video streaming nearly instantaneously, generating new frames approximately every 50 milliseconds (around 20 frames per second), ensuring that you don’t have to wait long for content but instead immerse yourself in an evolving narrative. Beneath its surface, the model employs an advanced multi-stage training process that shifts from generating fixed clips to creating open-ended interactive video experiences, granting you the ability to type or voice commands while exploring a world crafted by AI that responds in real-time. This innovative approach not only enhances engagement but also revolutionizes the way viewers interact with visual storytelling.
