Llama for pathology

Meta's natively multimodal, open-weight Mixture-of-Experts family (Scout and Maverick), free to download and self-host.

Not specifically recommended

Llama isn't on our list for pathology. It's usable for general work, but first look at the options we recommend for pathology.

What Llama does in pathology

Core tasks in pathology
  • Digitising and managing tissue slides in an image management system (scanners, LIMS, archive)
  • Detecting and grading cancer on H&E slides (e.g. Gleason score, mitotic counting, tumour size)
  • Counting and quantifying biomarkers in IHC stains (HER2, ER/PR, Ki-67, PD-L1)
  • Monitoring slide quality, prioritising cases and providing a second read as quality control
Where Llama is strong
  • Open weights, fully self-hostable
  • Fine-tunable on your own data
  • Very large context window (Scout 10M)
  • GPU-efficient (Mixture-of-Experts)

Llama raises a concrete GDPR point. The Llama 4 Acceptable Use Policy prohibits the multimodal models for businesses headquartered in the EU. Dutch companies may therefore not install the multimodal Llama 4 models themselves under the licence. Weigh this heavily before deploying it in pathology.

Confidentiality and GDPR

GDPR: Caution

You process special category personal data (health) and sometimes data for genetic research. Software for diagnostic use is an in vitro diagnostic medical device: check whether the algorithm is CE-marked under the IVDR for your exact application and tissue type. Many apps are 'research use only'. Choose providers with ISO 27001 and ISO 13485, a data processing agreement and clear data location (EU hosting or on-premise). Also ask whether your slides are used to train models. Under the EU AI Act, medical AI falling under the IVDR is classed as high-risk. Validate every algorithm locally on your own scanner and stains before using it in routine practice.

Self-hosting gives full data control within your own EU infrastructure, a strong GDPR argument.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
