How to update paper metadata with the latest version

Site Feedback

I have a paper on arXiv that has been updated to v5 (new title and abstract),

but the Hugging Face paper page is still showing the v1 metadata.

Paper: 2603.21045

arXiv: [2603.21045] LPNSR: Optimal Noise-Guided Diffusion Image Super-Resolution Via Learnable Noise Prediction

HF: Paper page - LPNSR: Prior-Enhanced Diffusion Image Super-Resolution via LR-Guided Noise Prediction

The arXiv API already returns the latest version:

I’ve waited about two weeks since the update went live on arXiv (v5, dated

2026-04-14), but the HF page hasn’t picked up the change.

Is there a way to trigger a re-index manually, or does anyone know the

typical sync delay for metadata updates? Any help appreciated — thanks!
