Introduction to GPT4All

GPT4All is an open-source software ecosystem managed by Nomic AI, designed to facilitate the training and deployment of large language models (LLMs) on conventional hardware. This initiative supports multiple model architectures, including GPT-J, LLaMA, MPT, Replit, Falcon, and StarCoder, catering to various use cases and requirements.

MINIMUM HARDWARE REQUIREMENTS
Before diving into the installation process, ensure your system meets the minimum requirements. You need a CPU with AVX or AVX2 support and at least 8GB of RAM for basic operations. However, to fully utilize GPT4All’s capabilities, having more RAM (up to 16GB) is advisable. Unlike traditional LLMs that demand extensive resources, GPT4All’s models are optimized for efficiency, requiring significantly less storage and computational power.

Installing GPT4All CLI

Follow these steps to install the GPT4All command-line interface on your Linux system:

  1. Install Python Environment and pip: First, you need to set up Python and pip on your system. Open a terminal and execute the following command: 
    $ sudo apt install -y python3-venv python3-pip wget

    This step ensures you have the necessary tools to create a virtual environment and manage Python packages.

  2. Create Environment: With Python and pip installed, create a virtual environment for GPT4All to keep its dependencies isolated from other Python projects. 
    $ python3 -m venv gpt4all-cli

    This command creates a new directory named gpt4all-cli, which will contain the virtual environment.

  3. Activate Python Environment: Before installing GPT4All and its dependencies, activate the virtual environment: 
    $ . gpt4all-cli/bin/activate; cd gpt4all-cli/

    This step changes your shell’s directory to the virtual environment and activates it.

  4. Install Package and Dependencies: Install GPT4All and Typer, a library for building CLI applications, within the virtual environment: 
    $ python3 -m pip install --upgrade gpt4all typer

    This command downloads and installs GPT4All and Typer, preparing your system for running GPT4All CLI tools.

  5. Download the Self-contained Python Script: Fetch the main script for the GPT4All CLI: 
    $ wget https://raw.githubusercontent.com/nomic-ai/gpt4all/main/gpt4all-bindings/cli/app.py

    This script is a ready-to-use Python application for interacting with GPT4All’s features directly from the command line.

  6. Run the Script: Finally, execute the script to start the CLI application: 
    $ python3 app.py repl


    This command launches the GPT4All CLI, allowing you to interact with the installed language models. SInce you just started the script will automatically download a default model now.
  7. Start chatting with your AI: Now you can start asking some questions.

Installing GPT4All GUI Application

For those who prefer a graphical interface, GPT4All also offers a GUI application. Follow these steps to install it:

  1. Download GPT4All Installation Binary: Retrieve the installer for the GPT4All GUI application: 
    $ wget https://gpt4all.io/installers/gpt4all-installer-linux.run

    This command downloads the installer script to your local system.

  2. Make Executable and Run the Installation Wizard: Change the permissions of the downloaded file to make it executable, then start the installation process: 
    $ chmod +x gpt4all-installer-linux.run

    now run the installer:

    ./gpt4all-installer-linux.run

    This step prepares and initiates the setup wizard for the GPT4All GUI application.

  3. Follow the Wizard to Install: The installer will guide you through the setup process, including selecting the installation path (default is ~/gpt4all in your home directory) and downloading necessary components.

  4. $ ~/gpt4all/bin/chat
    Select GPT4ALL model
    Select GPT4ALL model

    This command opens the GPT4All chat interface, where you can select and download models for use.

  5. Select Model to Download: Explore the available models and choose one to download. Be mindful of the model descriptions, as some may require an OpenAI key for certain functionalities.
