BiomedCLIP is a biomedical vision-language foundation model that is pretrained on PMC-15M, a dataset of 15 million figure-caption pairs extracted from biomedical research articles in PubMed Central, using contrastive learning. It uses PubMedBERT as the text encoder and Vision Transformer as the image encoder, with domain-specific adaptations. It can perform various vision-language processing (VLP) tasks such as cross-modal retrieval, image classification, and visual question answering. BiomedCLIP establishes new state of the art in a wide range of standard datasets, and substantially outperforms prior VLP approaches:

## Sample Input and Output (for real-time inference)
Virchow2 is a self-supervised vision transformer pretrained using 3.1M whole slide histopathology images. The model can be used as a tile-level feature extractor (frozen or finetuned) to achieve state-of-the-art results for a wide variety of downstream computational pathology use cases.
## Model Details
**Developed by:** Paige, NYC, USA and Microsoft Research, Cambridge, MA USA
KoLeo regularizer replaced with kernel density estimator
Crop-and-resize augmentation replaced with extended context translation
**Paper:**
Virchow2: Scaling Self-Supervised Mixed Magnification Models in Pathology https://arxiv.org/pdf/2408.00738
**Pretraining Dataset:** Internal dataset of 3.1 million whole slide images from Memorial Sloan Kettering Cancer Center, tiles sampled at 2.0, 1.0, 0.5 and 0.25 microns per pixel resolution (5x, 10x, 20x, and 40x magnification).
**License:** CC-BY-NC-ND-4.0
## Model Usage
**Direct use**
Virchow2 intended to be used as a frozen feature extractor as the foundation for tile-level and whole slide-level classifiers.
**Downstream use**
Virchow2 can be finetuned to adapt to specific tasks and/or datasets.
