117.6B parameters, published in BF16. View on Hugging Face
Set up Laguna-S-2.1Laguna-S-2.1 is published by poolside on Hugging Face, with 53,206 downloads and 1,010 likes to date. It's a LagunaForCausalLM 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 | 219.0 GB | 262.8 GB | RTX A6000 | 6 | $2.18/hr |
| FP8 (quantized) | 109.5 GB | 131.4 GB | RTX 4000 SFF Ada | 7 | $1.39/hr |
| INT4 (quantized) | 54.7 GB | 65.7 GB | A100 | 1 | $1.21/hr |
| cheaper alt. | RTX A5000 | 3 | $0.528/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 Laguna-S-2.1 at its published (BF16) precision: 6× RTX A6000, at $0.363/hr per GPU ($2.18/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Laguna-S-2.1: common questions
Can Laguna-S-2.1 run on a single GPU?
No. At BF16 it needs 262.8 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 6 of them.
How many GPUs do I need to run Laguna-S-2.1?
6 at BF16. It needs 262.8 GB of VRAM and the cheapest capable live offer is a 48.0 GB RTX A6000, so 6 of them come to $2.18/hr in total.
Does quantizing Laguna-S-2.1 lower the GPU bill?
Yes. At BF16 the cheapest live fit is 6 RTX A6000 cards at $2.18/hr. At INT4 (quantized) it drops to one A100 at $1.21/hr, provided a quantized checkpoint exists for it.
