DeepSeek R1 offers distilled models optimized for different hardware:

ModelVRAM RequirementUse Case
DeepSeek-R1-Distill-Qwen-1.5B~3.5 GBLightweight tasks, low-resource VMs
DeepSeek-R1-Distill-Qwen-7B~16 GBBalanced performance (recommended for most users) 12
DeepSeek-R1-Distill-Llama-70B~161 GBHigh-end tasks requiring multi-GPU setups

For Beginners: Start with the 7B model (4.7GB download) for a balance of speed and capability 210.


Step-by-Step Setup on Linux VM

Prerequisites

  1. VM Specifications:
    • OS: Ubuntu 22.04/Debian (64-bit) 37.
    • RAM: ≥16 GB (32 GB recommended for larger models).
    • Storage: ≥50 GB free space 3.
    • GPU (Optional): NVIDIA GPU with ≥8GB VRAM for acceleration 1.
  2. Install Dependencies:
sudo apt update && sudo apt install -y curl python3-pip  

Step 1: Install Ollama

Ollama simplifies local AI model management. Install it via:

curl -fsSL https://ollama.com/install.sh | sh  

Verify installation:

ollama --version  # Should display "ollama version 0.5.7" or later :cite[7]:cite[10]  

Step 2: Download the Model

Pull the 7B model (adjust 7b to 1.5b or 70b as needed):

ollama pull deepseek-r1:7b  

Check installed models:

ollama list  # Should list "deepseek-r1:7b" :cite[10]  

Step 3: Start the API Server

Launch Ollama in server mode:

ollama serve  

The API will run at http://localhost:11434.


Step 4: Test the API

Use curl or Python to send requests:

Example 1: Curl Request

curl http://localhost:11434/api/generate -d '{  
  "model": "deepseek-r1:7b",  
  "prompt": "Explain quantum computing in simple terms"  
}'  

Example 2: Python Integration

import ollama  

response = ollama.chat(  
    model='deepseek-r1:7b',  
    messages=[{'role': 'user', 'content': 'Write Python code for a Fibonacci sequence'}]  
)  
print(response['message']['content'])  

Advanced Tips

  1. GPU Acceleration: Enable CUDA support by installing NVIDIA drivers and adding --gpu to ollama serve .
  2. Optimize Performance: Limit response length with max_tokens and adjust creativity using temperature (0.7 recommended) 9.
  3. Web UI: Deploy Open Web UI for a ChatGPT-like interface:bashCopydocker run -d -p 3000:8080 ghcr.io/open-webui/open-webui:main Access at http://localhost:3000 46.

Troubleshooting

  • Model Not Found: Ensure you ran ollama pull and check for typos 10.
  • Out of Memory: Use a smaller model or upgrade VM specs 1.
  • Slow Responses: Disable background apps or use GPU acceleration 8.

Conclusion

Running DeepSeek R1 on a Linux VM is straightforward with Ollama. The 7B model offers the best balance for beginners, while the API integration opens doors for AI-powered apps. Experiment with different prompts and explore its reasoning prowess—your privacy-focused AI journey starts now!

FAQ Section: DeepSeek R1 on Linux VM

How do I choose between the 1.5B and 7B models?

The 1.5B model is ideal for basic tasks (e.g., text summarization, simple Q&A) on low-resource VMs (≤8GB RAM). The 7B model (recommended) handles complex reasoning, coding, and math problems better. If your VM has ≥16GB RAM and a mid-tier GPU, start with 7B for balanced performance.

Can I run the 70B model without a multi-GPU setup?

The 70B model requires ~161GB of VRAM, which typically needs enterprise-grade GPUs (e.g., 4x A100s). For personal VMs, stick to the 1.5B or 7B models. If you need 70B-level performance, consider cloud-based solutions like AWS/GCP.

What if my VM runs out of memory while using the 7B model?

  • Fix 1: Close background apps to free RAM.
  • Fix 2: Add swap space temporarily

sudo fallocate -l 8G /swapfile && sudo chmod 600 /swapfile
sudo mkswap /swapfile && sudo swapon /swapfile

  • Fix 3: Switch to the 1.5B model (ollama pull deepseek-r1:1.5b).

Can I use DeepSeek R1 without a GPU?

Yes! Ollama runs models on CPU by default, but responses will be slower. For GPU-like speed on CPU-only VMs, use quantization (e.g., ollama pull deepseek-r1:7b-q4_0).

How do I upgrade my VM later for larger models?

  1. Vertical Scaling: Increase VM RAM/CPU via your cloud provider (e.g., AWS EC2, Azure).
  2. GPU Add-ons: Attach a GPU (e.g., NVIDIA T4) if supported.
  3. Model Swap: Stop Ollama (sudo systemctl stop ollama), pull the new model, and restart.
