1.7B parameters, published in F32. View on Hugging Face
Set up SmolLM-1.7BSmolLM-1.7B is published by HuggingFaceTB on Hugging Face, with 68,727 downloads and 183 likes to date. It's a LlamaForCausalLM model built for text-generation, published natively in F32.
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) |
|---|---|---|---|---|---|
| FP32 | 6.4 GB | 7.7 GB | V100 | 1 | $0.088/hr |
| FP8 (quantized) | 1.6 GB | 1.9 GB | RTX 5060 Ti | 1 | $0.110/hr |
| INT4 (quantized) | 0.8 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 SmolLM-1.7B at its published (F32) precision: 1× V100, 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.
SmolLM-1.7B: common questions
Does SmolLM-1.7B fit on a 8 GB GPU?
Yes. At FP32 it needs 7.7 GB of VRAM, so an 8 GB card holds it with 0.3 GB to spare. A 6 GB card is not enough for it at FP32.
Can SmolLM-1.7B run in 16-bit instead of FP32?
Yes. Its published weights are FP32, 6.4 GB, or 7.7 GB once inference overhead is added. Loading the same weights in 16 bits halves that to 3.2 GB, or 3.8 GB with overhead. That moves it onto a 6 GB card instead of an 8 GB one. How much accuracy the cast costs is model-specific and is not measured here.
How many copies of SmolLM-1.7B fit on one V100?
2, by VRAM alone. That card carries 16.0 GB and one copy needs 7.7 GB at FP32, 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.
What is the least VRAM SmolLM-1.7B can run in?
1.0 GB, at INT4 (quantized), which fits a 6 GB card, against 7.7 GB at FP32. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
