What GPU do I need to run HuggingFaceTB/SmolVLM2-2.2B-Instruct?
2.2B parameters, published in F32. View on Hugging Face
Set up SmolVLM2-2.2B-InstructSmolVLM2-2.2B-Instruct is published by HuggingFaceTB on Hugging Face, with 162,729 downloads and 331 likes to date. It's a SmolVLMForConditionalGeneration model built for image-text-to-text, published natively in F32.
VRAM required & cheapest live GPU fit
Required VRAM = weight size at each precision times a flat 1.2 overhead for activations and fragmentation. The KV-cache grows with context and is not in that factor; it is listed per model below where the architecture is published. Full formula and assumptions: methodology.
| Precision | Weight size | Required VRAM | Cheapest live fit | GPUs needed | Est. $/hr (full fit) |
|---|---|---|---|---|---|
| FP32 | 8.4 GB | 10.0 GB | V100 | 1 | $0.088/hr |
| FP8 (quantized) | 2.1 GB | 2.5 GB | RTX 4000 SFF Ada | 1 | $0.198/hr |
| INT4 (quantized) | 1.0 GB | 1.3 GB | RTX 3060 | 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 SmolVLM2-2.2B-Instruct 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.
SmolVLM2-2.2B-Instruct: KV cache by context length
The KV cache is the memory the attention layers hold for every token of context, on top of the weights. It is not part of the flat 1.2x overhead in the table above, grows with context length and with every concurrent request, and is why a long-context deployment needs more VRAM than the table shows.
KV-cache size for SmolVLM2-2.2B-Instruct is not published for this architecture, so no figure is shown.
SmolVLM2-2.2B-Instruct: common questions
Does SmolVLM2-2.2B-Instruct fit on a 12 GB GPU?
Yes. At FP32 it needs 10.0 GB of VRAM, so a 12 GB card holds it with 2.0 GB to spare. An 8 GB card is not enough for it at FP32.
Can SmolVLM2-2.2B-Instruct run in 16-bit instead of FP32?
Yes. Its published weights are FP32, 8.4 GB, or 10.0 GB once inference overhead is added. Loading the same weights in 16 bits halves that to 4.2 GB, or 5.0 GB with overhead. That moves it onto a 6 GB card instead of a 12 GB one. How much accuracy the cast costs is model-specific and is not measured here.
What is the least VRAM SmolVLM2-2.2B-Instruct can run in?
1.3 GB, at INT4 (quantized), which fits a 6 GB card, against 10.0 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.
