519.0B parameters, published in BF16. View on Hugging Face
Set up A.X-K1A.X-K1 is published by skt on Hugging Face, with 11,438 downloads and 295 likes to date. It's a AXK1ForCausalLM 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 | 966.7 GB | 1160.0 GB | No capable live offer found | – | – |
| FP8 (quantized) | 483.3 GB | 580.0 GB | RTX PRO 6000 | 7 | $9.63/hr |
| INT4 (quantized) | 241.7 GB | 290.0 GB | RTX A6000 | 7 | $2.54/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.
A.X-K1: common questions
Can A.X-K1 run on a single GPU?
Not on a desktop card. At BF16 it needs 1160.0 GB of VRAM, more than a single 32 GB desktop card holds. No card currently listed on the marketplace both supports BF16 and has enough VRAM for it, so how many it would take is not something this page can answer today.
