Can Gemma 4 12B run on Galaxy Z Fold6?
YES — Runs, barely
Grade B · 55/100 · formula estimate
What this means
Our estimate says Gemma 4 12B should fit, but there is very little memory left for the operating system and other apps.
Download the Q4_0 version, which is about 7 GB. We expect it to use about 8.8 GB of the roughly 9 GB available to a model on this phone.
At the estimated speed, a roughly 300-word answer may take about 82 seconds to finish.
This result is calculated from the phone and model specifications. It has not been measured on this exact phone and setup.
