What GPU do I need to run google/gemma-4-31B-it?
31.3B parameters, published in BF16. View on Hugging Face
gemma-4-31B-it is published by google on Hugging Face, with 8,968,900 downloads and 3,617 likes to date. It's a Gemma4ForConditionalGeneration model built for image-text-to-text, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for KV-cache, activations, and fragmentation. Full formula and assumptions: methodology.
A GPU is only matched to a row if its hardware supports that precision, and the primary recommendation is always a single-GPU fit when one exists.
INT4 caveat: requires a quantized checkpoint actually published for this model — check its Hugging Face page before relying on this row.
Cheapest way to run gemma-4-31B-it at its published (BF16) precision: 1× A100 on vastai, at $1.15/hr per GPU ($1.15/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
