It runs inside PathAI's AISight product, but its weights are proprietary, so outside groups cannot benchmark or adapt it.","summary":"PLUTO is PathAI's compact pathology foundation model, a vision transformer pretrained at multiple resolutions with DINOv2 combined with masked autoencoding, so the same network works at the magnification a given task needs. The 2024 arXiv paper describes a lightweight multi-scale model trained on 195M tiles from 158k slides across 50+ sites, and it powers PathAI's AISight platform and biomarker quantification tools. It is aimed at laboratories and pharma partners who need efficient inference across many tasks rather than a separate model for each. Being proprietary, its weights cannot be independently benchmarked or adapted by outside groups, so external claims rest on the company's publications and deployments. For a newcomer: it is a smaller, efficient slide-reading model that is already inside a commercial pathology product.","status":"emerging","asOf":"2026-09-08","links":[{"label":"PLUTO (arXiv 2024)","url":"https://arxiv.org/abs/2407.07033"}],"tags":["foundation-model","pathology"],"related":[],"cancers":[],"sections":["ai-computation"],"technologies":["pathology-foundation-model"],"targets":[],"drugs":[],"companies":["pathai"],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"principle":"PLUTO is a ViT pretrained at multiple resolutions with DINOv2 plus masked autoencoding.","strengths":["Efficient","Deployed in PathAI products"],"limitations":["Proprietary"],"since":2024},"route":"/technologies/pluto/","neighbours":{"section":[{"id":"ai-computation","kind":"section","name":"AI & Computation","route":"/fronts/ai-computation/"}],"technology":[{"id":"pathology-foundation-model","kind":"technology","name":"Pathology & radiology foundation models","route":"/technologies/pathology-foundation-model/"}],"company":[{"id":"pathai","kind":"company","name":"PathAI","route":"/companies/pathai/"}]}}
