MedGemma 1.5 is a major upgrade to our open models for healthcare developers.

The new 4B model enables developers to build applications that natively interpret full 3D scans (CTs, MRIs) with high efficiency - a first, we believe, for an open medical generalist model. MedGemma 1.5 also pairs well with MedASR, our speech-to-text model fine-tuned for highly accurate medical dictation.

Developers can now use these multimodal capabilities to build medical apps that reach patients in more places.
