H-optimus-0, released in 2024, and H-optimus-1 are steps towards what the company calls a universal biology foundation model, starting from histology. OnCo links it to the H-optimus technology record. Whether a model that starts from histology can grow into a general model of biology, as the company intends, is the open question. H-optimus has its own technology page.","asOf":"2026-09-08","links":[{"label":"Official website","url":"https://www.bioptimus.com"}],"tags":["ai"],"related":[],"cancers":[],"sections":["ai-computation"],"technologies":["h-optimus"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"Paris","country":"FR","companyType":"ai-software","website":"https://www.bioptimus.com","investors":[],"funding":[]},"route":"/companies/bioptimus/","neighbours":{"section":[{"id":"ai-computation","kind":"section","name":"AI & Computation","route":"/fronts/ai-computation/"}],"technology":[{"id":"h-optimus","kind":"technology","name":"H-optimus (Bioptimus)","route":"/technologies/h-optimus/"}]}}
