The curator’s take
Google releases the MedGemma 1.5 technical report, introducing a 4B-parameter medical AI model that expands capabilities to 3D medical imaging (CT/MRI volumes), whole slide pathology, multi-timepoint chest X-ray analysis, and improved medical document understanding. The model achieves notable gains including a +47% macro F1 improvement on whole slide pathology and +22% on EHR question answering, positioning itself as an open foundation for next-generation medical AI systems.
