Harrison.ai has released Harrison.Rad 1.5, an update of its radiology-specific AI foundation model.
The new version builds on Harrison.Rad 1, which the company launched in 2024, and can now interpret a study in light of clinical questions being asked and the patient’s history, compare findings against prior studies, and generate a draft report in narrative radiologist prose, the company said. Other new capabilities include broader anatomical coverage and sharper localization across body parts.
Harrison.Rad 1.5 was trained on approximately 6 million diagnostic imaging studies, a 33% increase over Harrison.Rad 1, the company noted. It is available for research at chat.harrison.ai, with API access on request. Harrison.ai said it is pursuing regulatory clearance in the U.S. and EU; the model is not cleared for clinical use.
