Introduction to Llama 3.1

Llama 3.1 is an open-source AI model from Meta that you can fine-tune, distill, and deploy anywhere. Meta’s latest instruction-tuned model is available in 8B, 70B, and 405B versions. Llama 3.1 is known for its robust performance and versatility. It’s available in various sizes, from 8B (8 billion parameters) to 70B (70 billion parameters), and can be run entirely offline, making it ideal for private use.

An alternative to Llama 3.1 is Google Gemma 2. Gemma 2 offers three new, powerful, and efficient models available in 2, 9, and 27 billion parameter sizes, all with built-in safety advancements. It is a family of lightweight, state-of-the-art open models built from the same research and technology used to create the Gemini models. If you have computational limitations, I recommend installing the 2B version. Although you will lose some accuracy, it is very fast.

Learn how to run Llama 3.1 and other open-source large language models like Google Gemma 2 on your personal computer privately and offline.

Required Hardware Specifications

Before you start, ensure your computer meets the minimum hardware requirements:

  • CPU: Modern multi-core processor
  • RAM: At least 16 GB (32 GB recommended)
  • GPU: 4 GB of VRAM (for larger models)
  • Storage: HDD with sufficient space (5 GB for 8B model, 40 GB for 70B model, 231 GB for 45B model)

Step-by-Step Installation Guide

Downloading Ollama

The first step is to download Ollama, a free software required to run Llama 3.1. Visit ollama.com and download the appropriate version for your operating system (Mac, Windows, or Linux).

Using Terminal

Once Ollama is installed, open Terminal (or Command Prompt for Windows users). You’ll need to enter a specific command to install Llama 3.1:

ollama run llama3.1

This command will download and set up the initial model. Ensure you are connected to the internet during this process, as it needs to pull data from the web.

Installing other Models

After the basic setup, you can install specific models. For example, to install the Google Gemma 2model, use the following command in Terminal:

ollama run gemma2:2b

Similarly, for the Gemma 2 9B model:

ollama run gemma2

After Ollama loads the LLM, you can chat with it in the command line. However, as we want to chat with our files, we need to install Docker and Open Web UI. Below is an example chat with llama 3.1:

Setting Up Docker

Docker is required to run the models locally. Download Docker from docker.com and install it on your machine. After installation, open Docker and ensure it is running.

What is Docker?

Docker accelerates how you build, share, and run applications. It helps developers build, share, run, and verify applications anywhere — without tedious environment configuration or management.

Configuring Open Web UI

Open Web UI is an extensible, self-hosted interface for AI that adapts to your workflow, all while operating entirely offline. Visit the Open Web UI documentation for more details.

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 run Open Web UI with Nvidia GPU support, use this command:

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

For more information about installation, visit Open Web UI Getting Started.

Running Llama 3.1 Locally

With all the setup complete, you can now run Llama 3.1 on your computer. Open Docker and under the Containers tab click on the link under the port(s) column.

This opens the Open Web UI in your browser. You then need to create an admin account. The first account created on Open WebUI gains Administrator privileges, controlling user management and system settings. Subsequent sign-ups start with Pending status, requiring Administrator approval for access. All your data, including login details, is locally stored on your device. Open WebUI ensures strict confidentiality and no external requests for enhanced privacy and security.

Finally, select the Llama 3.1 model you installed. You can now interact with the model, run queries, and even upload files for it to process.

Exploring Llama 3.1 Capabilities

Llama 3.1 offers various functionalities, including text generation, document summarization, and more. You can test these capabilities through the Open Web UI by entering prompts and observing the responses. Additionally, you can integrate your own documents and knowledge bases for more personalized interactions.

Troubleshooting Common Issues

  1. Slow Performance: Ensure your hardware meets the necessary specifications. Larger models require more powerful GPUs and more RAM.
  2. Installation Errors: Double-check all commands entered in Terminal and ensure Docker is properly installed and running.
  3. Model Not Responding: Restart Docker and Terminal, and ensure all necessary software is up to date.

Conclusion

Running Llama 3.1 on your personal computer ensures complete privacy and gives you the flexibility to utilize a powerful LLM offline. By following the steps outlined in this guide, you can successfully set up and use Llama 3.1 for various applications.
