If you want to run AI models locally, you may want to know what Ollama is and how to use it. Ollama is a tool that allows you to run large language models (LLMs) directly on your computer instead of relying on cloud services.
It makes it easy to download, run, and interact with AI models such as Llama, Mistral, and others using simple commands. This guide explains what Ollama is and how to install and use it on Windows.
What Is Ollama?
Ollama is a platform designed to run AI language models locally on your computer. Instead of sending prompts to an online service, the models run directly on your system.
This allows users to:
- Run AI models offline
- Maintain privacy because data stays on your device
- Experiment with different AI models
- Build local AI applications
Ollama simplifies the process of downloading and running large AI models that normally require complex setup.

Ollama includes several features that make local AI easier to use.
Key features include:
- Local AI model execution
- Simple command-line interface
- Support for popular open-source models
- Easy model installation
- Offline AI interaction
Because everything runs locally, users have full control over the environment.
System Requirements for Ollama
Before installing Ollama, your computer should meet some basic requirements.
Typical requirements include:
- Windows 10 or Windows 11
