What GPU do I need to run upstage/Solar-Open2-250B?
250.3B parameters, published in BF16. View on Hugging Face
Solar-Open2-250B is published by upstage on Hugging Face, with 24,883 downloads and 752 likes to date. It's a SolarOpen2ForCausalLM 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-Open2-250B at its published (BF16) precision: 7× A100 on runpod, at $1.19/hr per GPU ($8.33/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.
