**BrainAnytime: Anatomy-Aware Cross-Modal Pretraining for Brain Image Analysis with Arbitrary Modality Availability**

This Hugging Face Space hosts the official code from GitHub. Full 3D multi-modal inference
requires preprocessed NIfTI volumes and GPU resources. Use the linked model repository for
finetuned checkpoints and run `finetune_main.py` / `test_main.py` locally for evaluation.
