What GPU do I need to run Audio8/ARK-ASR-3B?
4.1B parameters, published in BF16. View on Hugging Face
Set up ARK-ASR-3BARK-ASR-3B is published by Audio8 on Hugging Face, with 17,425 downloads and 95 likes to date. It's a ArkasrForConditionalGeneration model built for automatic-speech-recognition, published natively in BF16.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision, plus a fixed overhead for activations and allocator fragmentation. Speech models don't build the same growing KV-cache a text model does. Memory scales primarily with input audio length. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| BF16 | 7.6 GB | 9.1 GB | RTX 5060 Ti | 1 | $0.110/hr |
| FP8 (quantized) | 3.8 GB | 4.5 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 1.9 GB | 2.3 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 ARK-ASR-3B at its published (BF16) precision: 1× RTX 5060 Ti, at $0.110/hr per GPU ($0.110/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
ARK-ASR-3B: common questions
Does ARK-ASR-3B fit on a 12 GB GPU?
Yes. At BF16 it needs 9.1 GB of VRAM, so a 12 GB card holds it with 2.9 GB to spare. An 8 GB card is not enough for it at BF16.
What is the least VRAM ARK-ASR-3B can run in?
2.3 GB, at INT4 (quantized), which fits a 6 GB card, against 9.1 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.
