RAM figures are working-set recommendations: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Install it
Pair a computer with idapt and install Gemma 4 31B from the model page: the local engine bootstraps itself, pulls the build you pick, and streams progress. Or pull it directly:
ollama pull gemma4:31bFrequently asked
How much RAM do I need to run Gemma 4 31B locally?
The smallest Gemma 4 31B build runs with about 28 GB of system RAM; the largest needs 28 GB. RAM is the binding requirement: when GPU memory is short, the runtime spills to CPU and system memory instead of failing.
Which quantization of Gemma 4 31B should I pick?
Start with the default 31b build: a 20 GB download that wants about 28 GB of RAM. Smaller quantizations shrink the download and memory needs at some cost in output quality; larger ones do the reverse.
Do I need a GPU to run Gemma 4 31B?
No. A GPU with enough VRAM makes generation faster, but Gemma 4 31B runs on CPU and system RAM alone. Whether a build fits is decided by RAM; the GPU only changes speed.
How big is the Gemma 4 31B download?
About 20 GB for the single available build.
Can idapt install Gemma 4 31B for me?
Yes. Pair a computer with idapt and install Gemma 4 31B from this page: the local engine bootstraps itself, pulls the build you pick (ollama pull gemma4), and streams download progress. Local runs are not billed.
