LTX-2
This model card focuses on the LTX-2 model, as presented in the paper LTX-2: Efficient Joint Audio-Visual Foundation Model. The codebase is available here.
LTX-2 is a DiT-based audio-video foundation model designed to generate synchronized video and audio within a single model. It brings together the core building blocks of modern video generation, with open weights and a focus on practical, local execution.
Direct use license
You can use the models - full, distilled, upscalers and any derivatives of the models - for purposes under the license.
ComfyUI
We recommend you use the built-in LTXVideo nodes that can be found in the ComfyUI Manager. For manual installation information, please refer to our documentation site.
General tips:
Width & height settings must be divisible by 32. Frame count must be divisible by 8 + 1.
In case the resolution or number of frames are not divisible by 32 or 8 + 1, the input should be padded with -1 and then cropped to the desired resolution and number of frames.

Limitations
This model is not intended or able to provide factual information.
As a statistical model this checkpoint might amplify existing societal biases.
The model may fail to generate videos that matches the prompts perfectly.
Prompt following is heavily influenced by the prompting-style.
The model may generate content that is inappropriate or offensive.
When generating audio without speech, the audio may be of lower quality.
