Can I run Gemma 4 31B on Generic Android Phone (12GB RAM)?
No. Gemma 4 31B needs ~20.5 GB even at Q4_K_M, but Generic Android Phone (12GB RAM) only has ~8.5 GB usable.
Needs ~20.5 GB even at Q4_K_M, but only ~8.5 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 12 GB: Gemma 4 31B needs roughly 20.5 GB at Q4_K_M and Generic Android Phone (12GB RAM) leaves only about 8.5 GB usable for a model. The lightest tracked hardware that runs Gemma 4 31B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Gemma 4 31B on Nvidia GeForce RTX 4090 (24GB).
