What GPU do I need to run Salesforce/xLAM-8x22b-r?
140.6B parameters, published in BF16. View on Hugging Face
xLAM-8x22b-r is published by Salesforce on Hugging Face, with 17,853 downloads and 45 likes to date. It's a MixtralForCausalLM 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 | 261.9 GB | 314.3 GB | RTX A6000 | 7 | $2.54/hr |
| FP8 (quantized) | 131.0 GB | 157.2 GB | RTX 4000 SFF Ada | 8 | $1.58/hr |
| INT4 (quantized) | 65.5 GB | 78.6 GB | A100 | 1 | $1.21/hr |
| cheaper alt. | RTX 5060 Ti | 5 | $0.550/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 xLAM-8x22b-r at its published (BF16) precision: 7× RTX A6000, at $0.363/hr per GPU ($2.54/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
xLAM-8x22b-r: common questions
Can xLAM-8x22b-r run on a single GPU?
No. At BF16 it needs 314.3 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 48.0 GB RTX A6000, and it takes 7 of them.
How many GPUs do I need to run xLAM-8x22b-r?
7 at BF16. It needs 314.3 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX A6000, so 7 of them come to $2.54/hr in total.
Does quantizing xLAM-8x22b-r lower the GPU bill?
Yes. At BF16 the cheapest live fit is 7 RTX A6000 cards at $2.54/hr. At INT4 (quantized) it drops to one A100 at $1.21/hr, provided a quantized checkpoint exists for it.
