Digging deeper into Ollama and Ollama WebUI on a Windows computer is an exciting journey into the world of artificial intelligence and machine learning. This detailed guide walks you through each step and provides examples to ensure a smooth launch.

Download Ollama from https://ollama.com/download/windows, then right click on the downloaded OllamaSetup.exe file and run the installer as administrator. Once the installation is complete, Ollama is ready to use on your Windows system. An Ollama icon will be added to the tray area at the bottom of the desktop.

To run Ollama and start utilizing its AI models, you'll need to use a terminal on Windows. We'll skip it here and let's see how to install WebUI for a better experience.

Run the below docker command to deploy ollama-webui docker container on your local machine. If Ollama is on your computer, use this command:

docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

To connect to Ollama on another server, change the OLLAMA_BASE_URL to the server's URL. So if Ollama is on a Different Server, use this command:

docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=https://example.com -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

Note: When using Docker to install Open WebUI, make sure to include the -v open-webui:/app/backend/data in your Docker command. This step is crucial as it ensures your database is properly mounted and prevents any loss of data.

After installation, you can access Open WebUI at http://localhost:3000. For the first time you need to register by clicking "Sign up".

Once registered, you will be routed to the home page of ollama-webui.

Click the settings icon in the upper right corner to open the settings window, as shown in the figure below, enter the model tag（e.g. llama2:7b, gemma:2b）, click the download button on the right, and wait for the model to be downloaded.

As shown below, we have downloaded the gemma:2b and llama2:7b models, select gemma:2b.

Enter the prompt word "What is the future of AI?" and press Enter to send a message.

In this tutorial, we cover the basics of getting started with Ollama WebUI on Windows. Ollama stands out for its ease of use, automatic hardware acceleration, and access to a comprehensive model library. Ollama WebUI is what makes it a valuable tool for anyone interested in artificial intelligence and machine learning.
