The Safest Way to Use AI Models on Your Computer

In the rapidly evolving world of artificial intelligence, Deepseek has emerged as a game-changer. This powerful AI model has not only dethroned ChatGPT as the #1 app on app stores but has also demonstrated that sophisticated AI capabilities can be achieved with fewer resources than previously thought possible.

But with great power comes great responsibility, especially regarding data privacy and security. This comprehensive guide will walk you through why running Deepseek locally is important and how to do it safely.

Why You Should Run Deepseek Locally Rather Than Using the App or Website

The convenience of accessing Deepseek through their app or website comes at a potential cost: your data privacy. When you use Deepseek online, everything you input is stored on their servers. This means:

1. You no longer have exclusive control over your data
2. The information you share could be used in ways you don’t approve of
3. Your data is subject to the cybersecurity laws of the country where the servers are located

For Deepseek specifically, their servers are based in China, where authorities have broad powers to request access to data stored within their borders. This is a consideration regardless of which country’s government might have access to your data.

Running AI models locally keeps your data on your machine and off external servers.

How to Run Deepseek Locally: Two Excellent Options

Fortunately, running Deepseek locally has become remarkably straightforward, even for those without extensive technical knowledge. Here are two excellent options to choose from based on your comfort level with technology.

Option 1: LM Studio – Perfect for Everyone (GUI-Based)

LM Studio offers a beautiful graphical user interface that makes running local AI models accessible to everyone.

Installation Steps:

1. Visit LM Studio’s website
2. Download the version for your operating system (Windows, Mac, or Linux)
3. Follow the simple installation wizard
4. The wizard will guide you through installing your first local AI model (likely LLAMA 3 or similar)

Key Features:

• Intuitive interface for easy navigation
• Built-in model discovery to find and download Deepseek models
• Hardware compatibility check that tells you if your system can handle specific models
• Multiple quantization options for different hardware capabilities

Option 2: Ollama – Fast and Command-Line Based

For those comfortable with command-line interfaces, Ollama offers a streamlined, efficient approach to running local AI models.

Installation Steps:

1. Visit Ollama’s website
2. Download the version for your operating system
3. Open your terminal or command prompt
4. Type ollama -h to verify installation and see available commands
5. Run Deepseek with: ollama run deepseek-r1:1.5b (for the smallest model version)

Understanding Model Sizes and Hardware Requirements

When running AI models locally, it’s crucial to understand that model size significantly impacts performance and hardware requirements.

Deepseek Model Size Options:

• 1.5B (billion parameters) – Can run on most modern computers
• 7B – Requires a decent GPU
• 14B to 32B – Requires a high-end GPU (like NVIDIA 4090)
• 70B – Requires serious GPU hardware
• 671B – Requires enterprise-level hardware (not feasible for most users)

The model size directly correlates with its intelligence and capabilities. While smaller models may not match the performance of cloud-based options, they still offer impressive functionality while keeping your data private.

Verifying That Your Local AI Model Isn’t Phoning Home

A legitimate concern when running AI models locally is whether they’re truly “offline” or if they might be secretly accessing the internet and sharing your data. Here’s how to verify:

1. Run a network monitoring tool while using your local AI model
2. For Ollama, you can use a PowerShell script to monitor network connections:
   • The only connection you should see is a local listening port (typically port 11434)
   • This port allows your interface to communicate with the model but doesn’t connect to external servers
   • When downloading models, you’ll temporarily see external connections, which is normal and necessary

Maximum Security: Running Deepseek in a Docker Container

For the security-conscious user, running Deepseek inside a Docker container provides an additional layer of isolation and control.

Benefits of Using Docker:

• Isolates the application from your operating system
• Restricts access to network, files, and system settings
• Allows precise control over resources and permissions
• Provides read-only file system access for enhanced security

Requirements:

• Docker installed on your system
• For Windows: Windows Subsystem for Linux (WSL)
• For GPU access: NVIDIA Container Toolkit (for NVIDIA GPUs)

Example Docker Command for Ollama:

docker run -d \
  --gpus all \
  -v ollama:/root/.ollama \
  -p 11434:11434 \
  --name ollama \
  --privileged=false \
  --cap-drop=ALL \
  --cap-add=SYS_RESOURCE \
  --memory=16g \
  --cpu-shares=8192 \
  --read-only \
  ollama/ollama

Once running, you can interact with models using:

docker exec -it ollama ollama run deepseek-r1:1.5b

Conclusion: The Future of Private AI

Running Deepseek locally represents a significant shift in how we can interact with powerful AI tools while maintaining privacy. The breakthrough of Deepseek—achieving exceptional performance with fewer resources—signals that AI development is becoming more accessible and efficient.

By choosing to run these models locally, you’re not only protecting your data but also participating in a movement toward more private, user-controlled AI experiences. As hardware capabilities continue to improve, we can expect even more powerful models to become available for local use.

Whether you choose the user-friendly LM Studio or the efficient Ollama, running Deepseek locally provides a balance of powerful AI capabilities and enhanced privacy that cloud-based solutions simply cannot match.

FAQ

Q: Will running models locally be as good as using ChatGPT or Deepseek online? A: Smaller models run locally won’t match the capabilities of the largest models run on powerful cloud servers. However, they still provide impressive functionality while keeping your data private.

Q: How much RAM do I need to run Deepseek locally? A: For the 1.5B model, 8GB of RAM should be sufficient. Larger models require more RAM and ideally a dedicated GPU.

Q: Can I run Deepseek locally on a Mac with Apple Silicon? A: Yes, through LM Studio or Ollama directly, but currently not with Docker as it doesn’t support GPU access for Apple Silicon.

Q: Does running AI models locally use a lot of power? A: When actively using the model, especially larger ones with GPU acceleration, power consumption will increase significantly. The model only uses substantial resources when actively generating responses.

Q: How do I know which model size to choose? A: Start with the smallest (1.5B) and see if it meets your needs. If you have more powerful hardware and need more capabilities, gradually try larger models.
