| ## Overview |
|
|
| This repository hosts pre-trained checkpoints from the **OpenMind** benchmark, featuring the **Primus** architecture. Primus is a Transformer-centric segmentation architecture that leverages high-resolution tokens and advances in positional embeddings to achieve state-of-the-art results in 3D medical image segmentation. |
|
|
| Each model was pre-trained using a specific self-supervised learning (SSL) method on the [OpenMind Dataset](https://huggingface.co/datasets/AnonRes/OpenMind), a standardized collection of public brain MRI datasets. |
|
|
| **Note**: These models are intended to be used as weights for downstream fine-tuning for **segmentation** tasks using the [nnU-Net framework](https://github.com/MIC-DKFZ/nnUNet). |

|
| ## Model Variants |
|
|
| We release SSL checkpoints for two backbone architectures: |
|
|
| - **Primus-M**: A transformer-based encoder introduced in the [Primus paper](https://huggingface.co/papers/2503.01835). |
| - **ResEnc-L**: A CNN-based encoder. |
|
|
| Each encoder has been pre-trained using one of the following SSL techniques: |
