What GPU do I need to run tiiuae/falcon-7b-instruct?
7.2B parameters, published in BF16. View on Hugging Face
Set up falcon-7b-instructfalcon-7b-instruct is published by tiiuae on Hugging Face, with 32,823 downloads and 1,032 likes to date. It's a FalconForCausalLM model built for text-generation, published natively in BF16.
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) |
|---|---|---|---|---|---|
| BF16 | 13.4 GB | 16.1 GB | RTX A5000 | 1 | $0.176/hr |
| FP8 (quantized) | 6.7 GB | 8.1 GB | RTX 4070 Super | 1 | $0.121/hr |
| INT4 (quantized) | 3.4 GB | 4.0 GB | RTX 4070 Super | 1 | $0.121/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 falcon-7b-instruct at its published (BF16) precision: 1× RTX A5000, at $0.176/hr per GPU ($0.176/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
falcon-7b-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.
Grouped-query attention: every layer caches keys and values for a few shared KV heads. Cached per token: 8,192 bytes at 16-bit.
The model's maximum context length is not published in its configuration, so no per-context figures are shown.
Computed from the layer, head and window counts in the model's own configuration (tiiuae/falcon-7b-instruct), at 16 bits per cached value. Each concurrent sequence needs its own cache, on top of the weights.
falcon-7b-instruct: common questions
Does falcon-7b-instruct fit on a 24 GB GPU?
Yes. At BF16 it needs 16.1 GB of VRAM, so a 24 GB card holds it with 7.9 GB to spare. A 16 GB card is not enough for it at BF16.
What is the least VRAM falcon-7b-instruct can run in?
4.0 GB, at INT4 (quantized), which fits a 6 GB card, against 16.1 GB at BF16. That row assumes an INT4 checkpoint has actually been published for this model, so check its Hugging Face page before planning around it.
Does quantizing falcon-7b-instruct lower the GPU bill?
Yes. At BF16 the cheapest live fit is one RTX A5000 at $0.176/hr. At FP8 (quantized) it drops to one RTX 4070 Super at $0.121/hr, provided a quantized checkpoint exists for it.
