What GPU do I need to run Qwen/Qwen3-30B-A3B-Instruct-2507?
30.5B parameters, published in BF16. View on Hugging Face
Qwen3-30B-A3B-Instruct-2507 is published by Qwen on Hugging Face, with 1,358,659 downloads and 830 likes to date. It's a Qwen3MoeForCausalLM 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 requires a quantized checkpoint actually published for this model, check its Hugging Face page before relying on this row.
Cheapest way to run Qwen3-30B-A3B-Instruct-2507 at its published (BF16) precision: 1× RTX PRO 6000 on vastai, at $1.17/hr per GPU ($1.17/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Qwen3-30B-A3B-Instruct-2507: common questions
Can Qwen3-30B-A3B-Instruct-2507 run on a single GPU?
Yes, but not on a desktop card. At BF16 it needs 68.2 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest live single-card fit is a 96.0 GB RTX PRO 6000 on vastai at $1.17/hr.
What is the least VRAM Qwen3-30B-A3B-Instruct-2507 can run in?
17.1 GB, at INT4 (quantized), which fits a 24 GB card, against 68.2 GB at BF16. 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 Qwen3-30B-A3B-Instruct-2507 lower the GPU bill?
Yes. At BF16 the cheapest live fit is one RTX PRO 6000 on vastai at $1.17/hr. At INT4 (quantized) it drops to one RTX A5000 on runpod at $0.160/hr, provided a quantized checkpoint exists for it.
