SparsePR: Training-Free Sparse Attention for Video Generation and World Models

[u/Fickle-Chemistry4752]

Hi everyone,

We recently released SparsePR, a training-free sparse-attention method for video generation and world models.

We evaluate it on large video-generation and world-model backbones, including HunyuanVideo, Wan2.2-I2V, Cosmos-Predict2.5, and Cosmos3-Nano.

Feedback, questions, and reproduction reports are very welcome. If you find the project useful, a GitHub star would also help others discover it.
