What GPU do I need to run fdtn-ai/antares-1b?
1.8B parameters, published in BF16. View on Hugging FaceGated
Set up antares-1bantares-1b is published by fdtn-ai on Hugging Face, with 14,867 downloads and 291 likes to date. It's a GraniteMoeHybridForCausalLM model built for text-generation, published natively in BF16, and gated: you'll need to accept the model's terms on Hugging Face before downloading weights.
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 | 3.4 GB | 4.1 GB | RTX 5060 Ti | 1 | $0.110/hr |
| FP8 (quantized) | 1.7 GB | 2.1 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 0.9 GB | 1.0 GB | RTX 5060 Ti | 1 | $0.110/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 antares-1b at its published (BF16) precision: 1× RTX 5060 Ti, at $0.110/hr per GPU ($0.110/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
antares-1b: common questions
How much VRAM does antares-1b need?
4.1 GB at BF16, 2.1 GB at FP8 (quantized), 1.0 GB at INT4 (quantized). All of those sit under 6 GB, the smallest capacity this page reasons about, so VRAM is not what limits where this model runs. The 3.4 GB of weights plus inference overhead is the whole requirement.
Do I need approval to download antares-1b?
Yes. fdtn-ai gates this repository on Hugging Face, so you have to accept its terms with a signed-in account before the weights will download. It does not change the 4.1 GB the model needs once you have them.
How many copies of antares-1b fit on one RTX 5060 Ti?
3, by VRAM alone. That card carries 16.0 GB and one copy needs 4.1 GB at BF16, on a live rate of $0.110/hr for the whole card. Throughput is not modelled here, so 3 copies is not 3 times the requests served.
