On January 14, 2026, Google made a significant announcement—the launch of MedGemma 1.5, a cutting-edge, open-source medical AI model. This new iteration brings enhanced capabilities to the realm of medical imaging. It can proficiently handle three-dimensional volume representations of CT and MRI scans, as well as whole-slide histopathology images. In the medical field, these kinds of imaging techniques are crucial for accurate diagnosis and treatment planning. The ability to process such complex imaging data effectively is a major step forward. Moreover, alongside MedGemma 1.5, Google also rolled out the open-source medical speech-to-text model, MedASR. In the medical environment, where clear and accurate communication is vital, MedASR has proven itself to deliver outstanding performance in medical speech recognition. This can streamline various medical processes, from taking patient notes to facilitating remote consultations.
