FAQ
Common questions about MedGemma
What are the key differences between the 4B multimodal and 27B text-only MedGemma models?
The 4B multimodal model processes both medical images and text with 4 billion parameters, using a SigLIP image encoder. The 27B text-only model focuses exclusively on text processing with 27 billion parameters, optimized for deeper medical text comprehension and clinical reasoning.
Are MedGemma models ready for clinical use out of the box?
No, MedGemma models are not considered clinical-grade out of the box. Developers must validate their performance and make necessary improvements before deploying in production environments, especially for applications involving patient care.
How can I access MedGemma models for my development work?
MedGemma models are accessible on platforms like Hugging Face and Google Cloud, subject to the terms of use by the Health AI Developer Foundations. You can run them locally for experimentation or deploy them via Google Cloud for production-grade applications.
What types of medical images can the 4B multimodal model process?
The 4B multimodal model is pre-trained on diverse medical images including chest X-rays, dermatology images, ophthalmology images, and histopathology slides, making it adaptable for various medical imaging tasks.
What adaptation methods can improve MedGemma's performance for specific tasks?
Developers can use prompt engineering (few-shot examples), fine-tuning with their own medical data, and agentic orchestration with tools like web search, FHIR generators, and Gemini Live to enhance performance for specific use cases.
When was MedGemma released and by whom?
MedGemma was officially launched around May 20-22, 2025, during Google I/O 2025 by Google DeepMind, as part of their ongoing efforts to enhance healthcare through technology.
How does MedGemma compare to similar models of its size?
According to its model card on Google Developers, MedGemma's baseline performance is strong compared to similar-sized models. It has been evaluated on clinically relevant benchmarks, including open datasets and curated datasets, with a focus on expert human evaluations for tasks.
Are there any resources available for fine-tuning MedGemma?
Yes, resources including notebooks on GitHub are available to facilitate fine-tuning, such as a fine-tuning example using LoRA available at Google's MedGemma GitHub repository.
What are the hardware requirements for running MedGemma models?
The hardware requirements depend on the model variant. According to posts from Google AI, MedGemma models are designed to be efficient, with the ability to run fine-tuning and inference on a single GPU, making them more accessible than some larger models.
Does MedGemma support multilingual medical terminology?
Based on community discussions, there are questions about MedGemma's performance with non-English medical terminology, such as Japanese medical terms. This suggests that multilingual support may vary and could be an area for future improvement or fine-tuning.
