What GPU do I need to run microsoft/VibeVoice-ASR-BitNet?
323M parameters, published in F32. View on Hugging Face
Set up VibeVoice-ASR-BitNetVibeVoice-ASR-BitNet is published by microsoft on Hugging Face, with 13,587 downloads and 192 likes to date. It's a VibeVoiceForASRTraining model built for automatic-speech-recognition, published natively in F32.
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) |
|---|---|---|---|---|---|
| FP32 | 1.2 GB | 1.4 GB | Quadro M4000 | 1 | $0.058/hr |
| FP8 (quantized) | 0.3 GB | 0.4 GB | RTX 4000 SFF Ada | 1 | $0.198/hr |
| INT4 (quantized) | 0.2 GB | 0.2 GB | RTX 3060 | 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 VibeVoice-ASR-BitNet at its published (F32) precision: 1× Quadro M4000, at $0.058/hr per GPU ($0.058/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
VibeVoice-ASR-BitNet: common questions
How much VRAM does VibeVoice-ASR-BitNet need?
1.4 GB at FP32, 0.4 GB at FP8 (quantized), 0.2 GB at INT4 (quantized). All of those sit under 6 GB, the smallest capacity this page reasons about, so VRAM is not what limits where this model runs. The 1.2 GB of weights plus inference overhead is the whole requirement.
Can VibeVoice-ASR-BitNet run in 16-bit instead of FP32?
Yes. Its published weights are FP32, 1.2 GB, or 1.4 GB once inference overhead is added. Loading the same weights in 16 bits halves that to 0.6 GB, or 0.7 GB with overhead. How much accuracy the cast costs is model-specific and is not measured here.
How many copies of VibeVoice-ASR-BitNet fit on one Quadro M4000?
5, by VRAM alone. That card carries 8.0 GB and one copy needs 1.4 GB at FP32, on a live rate of $0.058/hr for the whole card. Throughput is not modelled here, so 5 copies is not 5 times the requests served.
