What GPU do I need to run moonshotai/Moonlight-16B-A3B-Instruct?
16.0B parameters, published in BF16. View on Hugging Face
Set up Moonlight-16B-A3B-InstructMoonlight-16B-A3B-Instruct is published by moonshotai on Hugging Face, with 62,167 downloads and 203 likes to date. It's a DeepseekV3ForCausalLM 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.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 29.7 GB | 35.7 GB | RTX A6000 | 1 | $0.363/hr |
| cheaper alt. | RTX 5060 Ti | 3 | $0.330/hr | ||
| FP8 (quantized) | 14.9 GB | 17.8 GB | RTX 4000 SFF Ada | 1 | $0.198/hr |
| INT4 (quantized) | 7.4 GB | 8.9 GB | RTX 5060 Ti | 1 | $0.110/hr |
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 Moonlight-16B-A3B-Instruct at its published (BF16) precision: 1× RTX A6000, at $0.363/hr per GPU ($0.363/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Moonlight-16B-A3B-Instruct: common questions
Can Moonlight-16B-A3B-Instruct run on a single GPU?
Yes, but not on a desktop card. At BF16 it needs 35.7 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest live single-card fit is a 48.0 GB RTX A6000 at $0.363/hr.
What is the least VRAM Moonlight-16B-A3B-Instruct can run in?
8.9 GB, at INT4 (quantized), which fits a 12 GB card, against 35.7 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 Moonlight-16B-A3B-Instruct lower the GPU bill?
Yes. At BF16 the cheapest live fit is one RTX A6000 at $0.363/hr. At INT4 (quantized) it drops to one RTX 5060 Ti at $0.110/hr, provided a quantized checkpoint exists for it.
