78.1B parameters, published in BF16. View on Hugging Face
Set up Kolibri-1-BF16Kolibri-1-BF16 is published by Aleph-Alpha on Hugging Face, with 862 downloads and 47 likes to date. It's a Kolibri1ForCausalLM 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 | 145.5 GB | 174.6 GB | RTX A5000 | 8 | $1.41/hr |
| FP8 (quantized) | 72.7 GB | 87.3 GB | RTX PRO 6000 | 1 | $1.53/hr |
| cheaper alt. | RTX 4090 | 2 | $0.962/hr | ||
| INT4 (quantized) | 36.4 GB | 43.6 GB | RTX A6000 | 1 | $0.363/hr |
| cheaper alt. | RTX A5000 | 2 | $0.352/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 Kolibri-1-BF16 at its published (BF16) precision: 8× RTX A5000, at $0.176/hr per GPU ($1.41/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
Kolibri-1-BF16: common questions
Can Kolibri-1-BF16 run on a single GPU?
No. At BF16 it needs 174.6 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 8 of them.
How many GPUs do I need to run Kolibri-1-BF16?
8 at BF16. It needs 174.6 GB of VRAM and the cheapest capable live offer is a 24.0 GB RTX A5000, so 8 of them come to $1.41/hr in total.
Does quantizing Kolibri-1-BF16 lower the GPU bill?
Yes. At BF16 the cheapest live fit is 8 RTX A5000 cards at $1.41/hr. At INT4 (quantized) it drops to one RTX A6000 at $0.363/hr, provided a quantized checkpoint exists for it.
