What GPU do I need to run fla-hub/transformer-1.3B-100B?
1.4B parameters, published in BF16. View on Hugging Face
Set up transformer-1.3B-100Btransformer-1.3B-100B is published by fla-hub on Hugging Face, with 94,916 downloads and 0 likes to date. It's a TransformerForCausalLM 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 | 2.5 GB | 3.0 GB | RTX 3070 | 1 | $0.088/hr |
| FP8 (quantized) | 1.3 GB | 1.5 GB | RTX 4070 | 1 | $0.121/hr |
| INT4 (quantized) | 0.6 GB | 0.8 GB | RTX 3070 | 1 | $0.088/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 transformer-1.3B-100B at its published (BF16) precision: 1× RTX 3070, at $0.088/hr per GPU ($0.088/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
transformer-1.3B-100B: common questions
How much VRAM does transformer-1.3B-100B need?
3.0 GB at BF16, 1.5 GB at FP8 (quantized), 0.8 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 2.5 GB of weights plus inference overhead is the whole requirement.
How many copies of transformer-1.3B-100B fit on one RTX 3070?
2, by VRAM alone. That card carries 8.0 GB and one copy needs 3.0 GB at BF16, on a live rate of $0.088/hr for the whole card. Throughput is not modelled here, so 2 copies is not 2 times the requests served.
