Cheapest GPU to run DeepSeek-V4-Pro-0813 by precision
Full precision. Best quality, highest memory.
8-bit quantized. ~2x smaller, minimal quality loss.
4-bit quantized. ~4x smaller, runs on smaller GPUs.
Inference vs fine-tuning DeepSeek-V4-Pro-0813
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. A model this size needs multiple GPUs even for inference, and full fine-tuning multiplies that again. Browse the GPU catalog to size a node. Check the live GPU pricing for current rates.

DeepSeek-V4-Pro-0813 GPU questions
DeepSeek-V4-Pro-0813 has about 1650B parameters. At FP16 it needs roughly 3598 GB of VRAM for inference, including weights, activations, and KV cache. Quantized to INT4 that drops to around 900 GB. Leave about 10% headroom for production traffic.
For FP16 inference, the cheapest fit on Spheron is a multi-node GPU cluster. If you quantize to INT4, 8x H200 141GB at about $33.76/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-Pro-0813. The VRAM matrix above shows the exact estimate for each setup.
We read the parameter count directly from the model's safetensors 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-Pro-0813 needs about 900 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 3598 GB, which usually means a data center GPU. The precision picks above list the cheapest GPU that fits each setup.
