Installing Ollama

Install on macOS and Linux

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

The script installs the ollama command and registers a service so models load on demand.

Install on Windows

Download the installer from ollama.com and run it. Ollama installs as a desktop app that starts with Windows, and the ollama command is available in PowerShell and CMD.

Verify the Install

ollama --version
ollama list

ollama list starts empty on a fresh install. The version command confirms the binary and the API are ready.

First Model

ollama run llama3.2

The first run downloads the model, which may take a few minutes, and then opens an interactive chat prompt.

Key Points

• Linux/macOS install with one curl command.
• Windows uses a desktop installer.
• Verify with ollama --version and ollama list.
• The first ollama run downloads the model automatically.
