Cheapest GPU to run DeepSeek-V4.1-Flash-1017-GGUF by precision
1632GB
Full precision. Best quality, highest memory.
816GB
8-bit quantized. ~2x smaller, minimal quality loss.
408GB
4-bit quantized. ~4x smaller, runs on smaller GPUs.
Inference vs fine-tuning DeepSeek-V4.1-Flash-1017-GGUF
Inference only holds the model weights plus a KV cache, so it is the cheapest setup. LoRA fine-tuning adds a small adapter and roughly 50% more memory. Full fine-tuning holds gradients and optimizer state on top of the weights, which is about 4x the inference footprint, so it often needs multiple GPUs even when inference fits on one. For DeepSeek-V4.1-Flash-1017-GGUF, an on-demand B300 288GB instance covers inference and LoRA, while a full fine-tune needs several times that memory and often spans multiple GPUs.

DeepSeek-V4.1-Flash-1017-GGUF GPU questions
VRAM, GPU choice and cost questions for running DeepSeek-V4.1-Flash-1017-GGUF on cloud GPUs.
DeepSeek-V4.1-Flash-1017-GGUF has about 748B parameters. At FP16 it needs roughly 1632 GB of VRAM for inference, including weights, activations, and KV cache. Quantized to INT4 that drops to around 408 GB. Leave about 10% headroom for production traffic.
For FP16 inference, the cheapest fit on Spheron is 8x B300 288GB at about $53.36/hr. If you quantize to INT4, 8x A100 80GB from $9.52/hr runs it for less. Pricing is aggregated live from 5+ data center partners with per-minute billing.
LoRA fine-tuning adds roughly 50% on top of inference memory, so it usually fits the same class of GPU. Full fine-tuning holds gradients and optimizer state and needs about 4x the inference VRAM, which often means multiple GPUs for DeepSeek-V4.1-Flash-1017-GGUF. The VRAM matrix above shows the exact estimate for each setup.
We read the parameter count from the model's GGUF metadata on HuggingFace, then estimate peak VRAM from weights, activations, KV cache, and framework overhead at your chosen precision. The estimate lands within about 15% of real-world use for most transformer models.
Quantized to INT4, DeepSeek-V4.1-Flash-1017-GGUF needs about 408 GB of VRAM, so it is too large for a single 24 GB RTX 4090 and needs a bigger card or multiple GPUs. At FP16 it needs roughly 1632 GB, which usually means a data center GPU. The precision picks above list the cheapest GPU that fits each setup.
No. Even quantized to INT4, DeepSeek-V4.1-Flash-1017-GGUF needs about 408 GB of VRAM, so it takes 6 x 80 GB GPUs at minimum, and 21 x 80 GB GPUs at FP16. The precision picks above show the cheapest GPU that fits each setup on Spheron.
DeepSeek-V4.1-Flash-1017-GGUF needs 21 x 80 GB GPUs at FP16 (about 1632 GB of VRAM), 11 x 80 GB GPUs at INT8 (816 GB) and 6 x 80 GB GPUs at INT4 (408 GB). At FP16 that is more than one 8-GPU node, so plan for a multi-node cluster with a fast interconnect. Smaller cards such as 48 GB or 24 GB GPUs need proportionally more of them.
DeepSeek-V4.1-Flash-1017-GGUF needs about 816 GB of VRAM at INT8, roughly half its FP16 footprint of 1632 GB. The cheapest INT8 fit on Spheron is 4x B300 288GB at about $26.68/hr. INT8 is the usual middle ground: half the memory of FP16, with a smaller quality drop than 4-bit quantization.
Running DeepSeek-V4.1-Flash-1017-GGUF around the clock at FP16 costs about $38,953 a month on 8x B300 288GB (730 hours at $53.36/hr). Quantized to INT4 it costs about $6,950 a month on 8x A100 80GB (730 hours at $9.52/hr at the spot rate, which can be reclaimed). Spheron bills per minute, so stopping the instance when it is idle cuts that figure directly.
DeepSeek-V4.1-Flash-1017-GGUF needs about 1632 GB at FP16, 816 GB at INT8 and 408 GB at INT4. Use FP16 when output quality matters most or you plan to fine-tune, INT8 for most production inference, and INT4 when cost or GPU size is the constraint: the cheapest INT4 fit is 8x A100 80GB from $9.52/hr.
