# DeepSeek-OCR-2 GPU requirements

DeepSeek-OCR-2 has 3.4B parameters. To serve it, plan for about 8.1 GB of GPU memory in 16-bit, 4.1 GB in 8-bit or 2.0 GB in 4-bit, including about 20% for the KV cache and activations.

It is a mixture of experts: 64 experts, 6 of them active for each token. All of them stay in GPU memory, so plan memory for all 3.4B parameters.

[Deploy it on Arrakis](/console/#/models?model=deepseek-ai/DeepSeek-OCR-2).

## What it takes to serve it

| Precision | Memory and the smallest setup |
|---|---|
| 16-bit | 8.1 GB: one [RTX 4090](/gpus/rtx-4090.html.md) or [RTX 3090](/gpus/rtx-3090.html.md), RTX 3090 from $0.19 per GPU-hour |
| 8-bit | 4.1 GB: one [RTX 4090](/gpus/rtx-4090.html.md) or [RTX 3090](/gpus/rtx-3090.html.md), RTX 3090 from $0.19 per GPU-hour |
| 4-bit | 2.0 GB: one [RTX 4090](/gpus/rtx-4090.html.md) or [RTX 3090](/gpus/rtx-3090.html.md), RTX 3090 from $0.19 per GPU-hour |

## What it takes to fine-tune it

| Method | Memory and the smallest setup |
|---|---|
| QLoRA | 2.4 GB: one [RTX 4090](/gpus/rtx-4090.html.md) or [RTX 3090](/gpus/rtx-3090.html.md), RTX 3090 from $0.19 per GPU-hour |
| LoRA | 8.1 GB: one [RTX 4090](/gpus/rtx-4090.html.md) or [RTX 3090](/gpus/rtx-3090.html.md), RTX 3090 from $0.19 per GPU-hour |
| Full fine-tuning | 54 GB: one [H100](/gpus/h100.html.md) or [A100](/gpus/a100.html.md), H100 from $1.65 per GPU-hour |

## Questions

**How much GPU memory does DeepSeek-OCR-2 need?** To serve it, about 8 GB in 16-bit, 4 GB in 8-bit, 2 GB in 4-bit, including about 20% for the KV cache and activations. To fine-tune it, about 2 GB with QLoRA, 8 GB with LoRA and 54 GB for full fine-tuning with Adam, before activations.

**Can I run DeepSeek-OCR-2 on one GPU?** Yes. In 16-bit it needs about 8.1 GB, which fits on one RTX 4090 or RTX 3090.

**What does it cost to run DeepSeek-OCR-2?** In 16-bit it needs one RTX 4090 or RTX 3090; in 4-bit, one RTX 4090 or RTX 3090. 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-OCR-2 on Arrakis?** Open Models in the Arrakis console, paste deepseek-ai/DeepSeek-OCR-2, 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.
