What GPU do I need to run netease-youdao/Confucius4-R2T2?
2.0B parameters, published in BF16. View on Hugging Face
Set up Confucius4-R2T2Confucius4-R2T2 is published by netease-youdao on Hugging Face, with 18,709 downloads and 524 likes to date. It's a Qwen3ASRForConditionalGeneration 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 | 3.8 GB | 4.6 GB | RTX 3070 | 1 | $0.088/hr |
| FP8 (quantized) | 1.9 GB | 2.3 GB | RTX 4070 | 1 | $0.121/hr |
| INT4 (quantized) | 0.9 GB | 1.1 GB | RTX 3070 | 1 | $0.088/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 Confucius4-R2T2 at its published (BF16) precision: 1× RTX 3070, at $0.088/hr per GPU ($0.088/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Confucius4-R2T2: common questions
How much VRAM does Confucius4-R2T2 need?
4.6 GB at BF16, 2.3 GB at FP8 (quantized), 1.1 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 3.8 GB of weights plus inference overhead is the whole requirement.
