What GPU do I need to run upstage/Solar-Open-100B?
102.7B parameters, published in BF16. View on Hugging Face
Solar-Open-100B is published by upstage on Hugging Face, with 14,753 downloads and 495 likes to date. It's a SolarOpenForCausalLM 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.
Cheapest way to run Solar-Open-100B at its published (BF16) precision: 5× A40 on runpod, at $0.440/hr per GPU ($2.20/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Weight-to-VRAM math, the fit rules, and how live prices are normalized: full methodology.
