 ## Overview

-📄 **An OpenMind for 3D medical vision self-supervised learning** (Wald, T., Ulrich, C., Suprijadi, J., Ziegler, S., Nohel, M., Peretzke, R., ... & Maier-Hein, K. H. (2024).)  
-([arXiv:2412.17041](https://arxiv.org/abs/2412.17041)) — the first extensive benchmark study for **self-supervised learning (SSL)** on **3D medical imaging** data.
+This repository hosts pre-trained checkpoints from the **OpenMind** benchmark, the first extensive benchmark study for **self-supervised learning (SSL)** on **3D medical imaging** data.
+
+It specifically includes weights for the **Primus** architecture, a Transformer-centric segmentation model designed to maximally leverage self-attention for medical tasks. Primus surpasses current Transformer-based methods and competes with state-of-the-art CNNs like ResEnc-L and MedNeXt.
 
-Each model was pre-trained using a particular SSL method on the [OpenMind Dataset](https://huggingface.co/datasets/AnonRes/OpenMind), a large-scale, standardized collection of public brain MRI datasets.

-**These models are not recommended to be used as-is for feature extraction.** Instead we recommend using the downstream fine-tuning frameworks for **segmentation** and **classification** adaptation, available in the [adaptation repository](https://github.com/TaWald/nnUNet).
-*While manual download is possible, we recommend using the auto-download feature of the fine-tuning repository by providing the repository URL on Hugging Face instead of a local checkpoint path.*
