What GPU do I need to run ornith-ai/Ornith-1.5-397B?
403.4B parameters, published in BF16. View on Hugging Face
Ornith-1.5-397B is published by ornith-ai on Hugging Face, with 283,560 downloads and 84 likes to date. It's a Qwen3_5MoeForConditionalGeneration model built for text-generation, 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.
Weight-to-VRAM math, the fit rules, and how live prices are normalized: full methodology.
