Will MedGemma run on your machine?
This is the same sizing the app uses - not a marketing estimate.
On Apple Silicon, system memory is also graphics memory - pick "None / integrated / Apple Silicon" and read the bars against your Mac's memory. The app checks your real hardware before every download.

The app picks the right variant for your machine and verifies every download. Model files come straight from their official repositories, pinned to exact revisions.
