KRONOS

A self-supervised vision model for feature extraction from multiplexed tissue images in spatial proteomics.

What KRONOS is

KRONOS is a foundation vision model developed by MahmoodLab for spatial proteomics and multiplexed tissue imaging. It operates in the domains of biology, medicine, and computational pathology.

The model addresses the challenge of analysing highly multiplexed tissue imagery across varying experimental panels and imaging modalities. By providing standardised feature representations from complex multiplexed microscopy data, it supports researchers studying spatial protein expression and tissue architecture.

How it works

KRONOS is built on a Vision Transformer Small architecture with 16x16 patch tokens (ViT-S/16). It is trained using self-supervised learning techniques directly on highly multiplexed tissue images, enabling it to learn visual representations across diverse imaging modalities and marker panels without requiring manual annotations.

Run it here

We list this model but cannot run it yet: gated on the Hub — never run past a gate the user did not accept.

Everything on this page still applies. Running it needs a loader for this repository, not a bigger machine.

Strengths and limits

Good at

  • Pretrained across diverse multiplexed tissue imaging modalities and marker panels.
  • Employs self-supervised pretraining, avoiding reliance on manually annotated ground truth labels.
  • Uses a standard ViT-S/16 architecture tailored for high-dimensional spatial proteomics data.

Watch out for

  • Designed specifically for feature extraction rather than end-to-end task prediction.
  • Performance and compatibility details for specific custom antibody panels are not specified.

Inputs and outputs

You provide

  • Image

    PNG, JPEG or TIFF. Sent to the model as-is.

You get back

  • Mean-pooled representation, one vector per input.
