Google Research announces MedGemma 1.5 4B, an update to the open MedGemma model with improved support for high-dimensional medical imaging (CT, MRI, histopathology), longitudinal imaging, anatomical localization, and medical document understanding. They also describe MedASR, a new open medical speech-to-text model. Both remain free for research and commercial use.

## Evidence

Verbatim from https://research.google/blog/next-generation-medical-image-interpretation-with-medgemma-15-and-medical-speech-to-text-with-medasr/:

> Today, we’re building on that momentum by releasing MedGemma 1.5 4B and launching the MedGemma Impact Challenge hackathon on Kaggle. ... We also recently released MedASR (on Hugging Face and Vertex AI), a new open automated speech recognition (ASR) model that was fine-tuned for medical dictation.
