What GPU do I need to run nvidia/Llama-3.1-8B-Instruct-FP8?
8.0B parameters, published in F8_E4M3. View on Hugging Face
Llama-3.1-8B-Instruct-FP8 is published by nvidia on Hugging Face, with 32,956 downloads and 36 likes to date. It's a LlamaForCausalLM model built for text-generation, published natively in F8_E4M3.
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 Llama-3.1-8B-Instruct-FP8 at its published (F8_E4M3) precision: 1× RTX 4070 on simplepod, at $0.080/hr per GPU ($0.080/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
