What GPU do I need to run google/gemma-3-1b-it?
1000M parameters, published in BF16. View on Hugging FaceGated
Set up gemma-3-1b-itgemma-3-1b-it is published by google on Hugging Face, with 3,207,410 downloads and 1,122 likes to date. It's a Gemma3ForCausalLM model built for text-generation, published natively in BF16, and gated: you'll need to accept the model's terms on Hugging Face before downloading weights.
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 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run gemma-3-1b-it at its published (BF16) precision: 1× RTX 3070 on simplepod, at $0.050/hr per GPU ($0.050/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
gemma-3-1b-it: common questions
How much VRAM does gemma-3-1b-it need?
2.2 GB at BF16, 1.1 GB at FP8 (quantized), 0.6 GB at INT4 (quantized). All of those sit under 6 GB, the smallest capacity this page reasons about, so VRAM is not what limits where this model runs. The 1.9 GB of weights plus inference overhead is the whole requirement.
Do I need approval to download gemma-3-1b-it?
Yes. google gates this repository on Hugging Face, so you have to accept its terms with a signed-in account before the weights will download. It does not change the 2.2 GB the model needs once you have them.
How many copies of gemma-3-1b-it fit on one RTX 3070?
3, by VRAM alone. That card carries 8.0 GB and one copy needs 2.2 GB at BF16, on a live rate of $0.050/hr for the whole card. Throughput is not modelled here, so 3 copies is not 3 times the requests served.
