What GPU do I need to run NousResearch/Llama-2-7b-hf?
6.7B parameters, published in F16. View on Hugging Face
Set up Llama-2-7b-hfLlama-2-7b-hf is published by NousResearch on Hugging Face, with 234,880 downloads and 177 likes to date. It's a LlamaForCausalLM model built for text-generation, published natively in F16.
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 Llama-2-7b-hf at its published (F16) precision: 1× V100 on simplepod, at $0.060/hr per GPU ($0.060/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Llama-2-7b-hf: common questions
Does Llama-2-7b-hf fit on a 16 GB GPU?
Yes. At FP16 it needs 15.1 GB of VRAM, so a 16 GB card holds it with 0.9 GB to spare. A 12 GB card is not enough for it at FP16.
What is the least VRAM Llama-2-7b-hf can run in?
3.8 GB, at INT4 (quantized), which fits a 6 GB card, against 15.1 GB at FP16. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
Does quantizing Llama-2-7b-hf lower the GPU bill?
Yes. At FP16 the cheapest live fit is one V100 on simplepod at $0.060/hr. At INT4 (quantized) it drops to one RTX 3070 on simplepod at $0.050/hr, provided a quantized checkpoint exists for it.
