What GPU do I need to run unsloth/DeepSeek-V3?
684.5B parameters, published in F8_E4M3. View on Hugging Face
Set up DeepSeek-V3DeepSeek-V3 is published by unsloth on Hugging Face, with 16,812 downloads and 13 likes to date. It's a DeepseekV3ForCausalLM model built for text-generation, published natively in F8_E4M3.
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) |
|---|---|---|---|---|---|
| FP8 (native) | 637.5 GB | 765.0 GB | RTX PRO 6000 | 8 | $12.33/hr |
| INT4 (quantized) | 318.8 GB | 382.5 GB | RTX A6000 | 8 | $2.90/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 DeepSeek-V3 at its published (F8_E4M3) precision: 8× RTX PRO 6000, at $1.54/hr per GPU ($12.33/hr total). Quantizing to FP8 or INT4 (rows above) can cost less, but requires a compatible quantized checkpoint to exist for this model.
DeepSeek-V3: common questions
Can DeepSeek-V3 run on a single GPU?
No. At FP8 (native) it needs 765.0 GB of VRAM, more than a single 32 GB desktop card holds. The cheapest capable card in the live feed is a 96.0 GB RTX PRO 6000, and it takes 8 of them.
Is DeepSeek-V3 already quantized?
Yes. It is published in FP8, one byte per parameter, so the 765.0 GB figure is already a quantized footprint rather than a full-precision one. Only INT4 goes below it, at 382.5 GB. A GPU without FP8 tensor cores cannot run it as published, which is why cards here are matched on precision support and not on VRAM alone.
How many GPUs do I need to run DeepSeek-V3?
8 at FP8 (native). It needs 765.0 GB of VRAM and the cheapest capable live offer is a 96.0 GB RTX PRO 6000, so 8 of them come to $12.33/hr in total.
Does quantizing DeepSeek-V3 lower the GPU bill?
Yes. At FP8 (native) the cheapest live fit is 8 RTX PRO 6000 cards at $12.33/hr. At INT4 (quantized) it drops to 8 RTX A6000 cards at $2.90/hr, provided a quantized checkpoint exists for it.
