 # LTX-2 Model Card
-This model card focuses on the LTX-2 model, codebase available [here](https://github.com/Lightricks/LTX-2).
+
+This model card focuses on the LTX-2 model, as presented in the paper [LTX-2: Efficient Joint Audio-Visual Foundation Model](https://huggingface.co/papers/2601.03233). The codebase is available [here](https://github.com/Lightricks/LTX-2).
 
 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.

 It's extremely easy to reproduce the LoRAs and IC-LoRAs we publish with the model by following the instructions on the [LTX-2 Trainer Readme](https://github.com/Lightricks/LTX-2/blob/main/packages/ltx-trainer/README.md).
 
 Training for motion, style or likeness (sound+appearance) can take less than an hour in many settings.
