# DeepSeek-V3-0324 GPU requirements

DeepSeek-V3-0324 has 685B parameters. To serve it, plan for about 1,643 GB of GPU memory in 16-bit, 821 GB in 8-bit or 411 GB in 4-bit, including about 20% for the KV cache and activations.

It is a mixture of experts: 256 experts, 8 of them active for each token. All of them stay in GPU memory, so plan memory for all 685B parameters.

## What it takes to serve it

| Precision | Memory and the smallest setup |
|---|---|
| 16-bit | 1,643 GB: 8 × [B300](/gpus/b300.html.md), from $36.80 per hour for all 8 |
| 8-bit | 821 GB: 4 × [B300](/gpus/b300.html.md), from $18.40 per hour for all 4 |
| 4-bit | 411 GB: 2 × [B300](/gpus/b300.html.md), from $9.20 per hour for all 2 |

## What it takes to fine-tune it

| Method | Memory and the smallest setup |
|---|---|
| QLoRA | 479 GB: 2 × [B300](/gpus/b300.html.md), from $9.20 per hour for all 2 |
| LoRA | 1,643 GB: 8 × [B300](/gpus/b300.html.md), from $36.80 per hour for all 8 |
| Full fine-tuning | 10,953 GB: more than one 8-GPU machine |

## Questions

**How much GPU memory does DeepSeek-V3-0324 need?** To serve it, about 1,643 GB in 16-bit, 821 GB in 8-bit, 411 GB in 4-bit, including about 20% for the KV cache and activations. To fine-tune it, about 479 GB with QLoRA, 1,643 GB with LoRA and 10,953 GB for full fine-tuning with Adam, before activations.

**Can I run DeepSeek-V3-0324 on one GPU?** No. Even in 4-bit it needs about 411 GB: 2 B300 GPUs.

**What does it cost to run DeepSeek-V3-0324?** In 16-bit it needs 8 B300 GPUs; in 4-bit, 2 B300 GPUs. Each setup on this page shows the lowest price per GPU-hour on Arrakis right now, and you pay by the hour from a prepaid balance.

**How do I deploy DeepSeek-V3-0324 on Arrakis?** Open Models in the Arrakis console, paste deepseek-ai/DeepSeek-V3-0324, choose vLLM, SGLang or llama.cpp, and rent a GPU it fits on. You get an OpenAI-compatible endpoint with its own API key, and root SSH to the machine.
