Installing Ollama on Your System

Before we dive into running Ollama, let’s set up your system. The installation process may differ based on your operating system. For macOS users, you can install Ollama using Homebrew, a package manager that simplifies the installation of software on macOS.

For macOS:

First, ensure Homebrew is installed on your system, then run the following command in your terminal to install Ollama:

brew install ollama

For Linux and WSL2:

For Linux and Windows Subsystem for Linux 2 (WSL2) users, Ollama requires a manual installation. Visit the Ollama download page and select the installation instructions for your specific OS.

Running Your First Language Model

After installation, you can start a language model by entering a command into your terminal. Ollama supports several open-source models which are accessible from their library.

To fire up Llama 2, for instance, after the installation is complete, enter:

ollama run llama2

If Llama 2 is not installed on your system, Ollama will begin the download process.

Running Ollama as a Server with API Access

Ollama isn’t just for individual model runs – it can also operate as a server with a REST API for managing models. This server functionality enables integration into your personal or enterprise applications, allowing others to access the models you’ve set up.

Configuring Ollama Server

To commence an Ollama server instance, use the following command:

ollama serve

Your server will now be running, and you can call the REST API using a client of your choice to interact with your models.

curl http://localhost:11434/api/generate -d '{
  "model": "llama2",
  "prompt":"Why is the sky blue?"
}'
