51.6B parameters, published in BF16. View on Hugging Face
Set up Jamba-v0.1Jamba-v0.1 is published by ai21labs on Hugging Face, with 11,925 downloads and 1,194 likes to date. It's a JambaForCausalLM 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 | 96.1 GB | 115.3 GB | RTX A5000 | 5 | $0.880/hr |
| FP8 (quantized) | 48.0 GB | 57.6 GB | RTX PRO 6000 | 1 | $1.38/hr |
| cheaper alt. | RTX 5060 Ti | 4 | $0.440/hr | ||
| INT4 (quantized) | 24.0 GB | 28.8 GB | RTX 4080 Super | 1 | $0.338/hr |
| cheaper alt. | RTX 5060 Ti | 2 | $0.220/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 Jamba-v0.1 at its published (BF16) precision: 5× RTX A5000, at $0.176/hr per GPU ($0.880/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Jamba-v0.1: common questions
Can Jamba-v0.1 run on a single GPU?
No. At BF16 it needs 115.3 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 24.0 GB RTX A5000, and it takes 5 of them.
How many GPUs do I need to run Jamba-v0.1?
5 at BF16. It needs 115.3 GB of VRAM and the cheapest capable live offer is a 24.0 GB RTX A5000, so 5 of them come to $0.880/hr in total.
What is the least VRAM Jamba-v0.1 can run in?
28.8 GB, at INT4 (quantized), which fits a 32 GB card, against 115.3 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 Jamba-v0.1 lower the GPU bill?
Yes. At BF16 the cheapest live fit is 5 RTX A5000 cards at $0.880/hr. At INT4 (quantized) it drops to one RTX 4080 Super at $0.338/hr, provided a quantized checkpoint exists for it.
