Thank you for using xDiT to accelerate LTX. Would you mind adding this project to our homepage and providing some performance comparison data? Your PR is warmly welcomed!

Thank you for your open-source project! By using xDiT to accelerate LTX-Video, I was able to reduce the video generation time from 26s to 12s (including the VAE decoding stage). However, when scaling from one H100 to four H100s, it seems that there might be some issues with my code, which is causing xDiT’s performance boost to not be as significant as with other algorithms.

Additionally, during inference with 8 GPUs, the speed is actually slower than with 4 GPUs, which is why I haven’t submitted a PR yet. I would be very interested to see if you can validate whether xDiT applied to LTX-Video exhibits the same behavior I’ve described.

I’ve attached the sample results for reference.

Thanks again for your work!
