Hi! I'm Niels from the Hugging Face team.
This PR improves the model card for Internal Guidance (IG) by:
- Linking the repository to its [original paper](https://huggingface.co/papers/2512.24176) and project page.
- Adding relevant metadata tags for better discoverability.
- Summarizing key results (FID scores) on ImageNet 256x256.
- Adding the BibTeX citation for researchers to attribute the work.
Please review and merge if this looks good!
