Guide to Installing and Running Free AI Models on Your Computer: Llama 3, DeepSeek-R1 with Ollama

Introduction

Artificial intelligence is no longer limited to large-scale cloud services. With Ollama, you can run free AI models like Llama 3 and DeepSeek-R1 locally on your computer, enabling advanced natural language processing without requiring an internet connection. This guide will take you through everything you need to know to install, configure, and use these AI models efficiently.

Why Run AI Models Locally?

• Data Privacy: No need to send sensitive data to external servers.
• Offline Functionality: AI models run without an internet connection.
• Cost Savings: Avoid cloud computing fees by leveraging local hardware.
• Customization: Fine-tune models for specific use cases.

Prerequisites

Before proceeding, ensure your computer meets the following requirements:

Minimum System Requirements

• Operating System: Windows, macOS, or Linux
• Processor: x86_64 or ARM64 architecture
• RAM: At least 8GB (Recommended: 16GB for optimal performance)
• Storage: 20GB free disk space
• GPU (Optional): NVIDIA CUDA-compatible GPU for acceleration

Step 1: Installing Ollama

Ollama is a lightweight runtime environment that simplifies running large language models (LLMs) on your computer.

Install Ollama on Windows

1. Download the Ollama installer from the official site: https://ollama.com
2. Run the installer and follow the on-screen instructions.
3. Verify the installation by opening Command Prompt (cmd) and running:

   • curl -fsSL https://ollama.com/install.sh | sh
2. Verify the installation:
   • ollama --version

Step 2: Downloading and Running Free AI Models

Ollama supports multiple LLMs (Large Language Models), including Llama 3 and DeepSeek-R1.

Running Llama 3

ollama run llama3

• If not already installed, Ollama will automatically download the Llama 3 model.

Running DeepSeek-R1

ollama run deepseek

• DeepSeek-R1 is optimized for logical reasoning and scientific applications.

Listing Available Models

To check installed models:

ollama list

Removing Unused Models

If you need to free up space:

ollama remove llama3

Step 3: Customizing AI Models

You can create custom models using a Modelfile.

Example: Creating a Custom LLM

Create a new file named Modelfile:

echo "FROM llama3\nPARAMETER temperature=0.7" > Modelfile

Build the model:

ollama create mymodel -f Modelfile

Run your custom model:

ollama run mymodel

Step 4: Using Ollama with Python

For developers, Ollama provides Python API support.

Installing the Ollama Python Library

pip install ollama

Example: Running Llama 3 in Python

import ollama

response = ollama.chat(model='llama3', messages=[
    {'role': 'user', 'content': 'What is the capital of France?'}
])

print(response['message']['content'])

Step 5: Advanced Use Cases

Fine-tuning Models

You can fine-tune models for specific applications like chatbots, document summarization, and code generation.

Running AI Models on GPU

For performance improvements, configure Ollama to use NVIDIA GPU:

export OLLAMA_USE_CUDA=1

FAQ

1. Can I run Ollama without a GPU?

Yes, but performance will be better with a GPU, especially for large models.

2. How much RAM do I need?

For best results, at least 16GB RAM is recommended.

3. Can I use Ollama for commercial applications?

Yes, but check the licensing of the specific AI models you use.

4. How do I update Ollama?

Run:

ollama update

5. Where can I find more AI models?
