DeepSeek-R1-Distill-Qwen-7B | ~16 GB | Balanced performance (recommended for most users) 12 |
DeepSeek-R1-Distill-Llama-70B | ~161 GB | High-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
- 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.
- 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
- GPU Acceleration: Enable CUDA support by installing NVIDIA drivers and adding
--gpu
toollama serve
. - Optimize Performance: Limit response length with
max_tokens
and adjust creativity usingtemperature
(0.7 recommended) 9. - 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?
- Vertical Scaling: Increase VM RAM/CPU via your cloud provider (e.g., AWS EC2, Azure).
- GPU Add-ons: Attach a GPU (e.g., NVIDIA T4) if supported.
- Model Swap: Stop Ollama (
sudo systemctl stop ollama
), pull the new model, and restart.
