Machine Learning in Linux: GPT4All – local AI chat application

GPT4All Chat is a locally-running AI chat application powered by the GPT4All-J Apache 2 Licensed chatbot. The software lets you communicate with a large language model (LLM) to get helpful answers, insights, and suggestions.

The model runs on a local computer’s CPU and doesn’t require a net connection. No chat data is sent to external services.

This is free and open source cross-platform software.

Installation

We will take you through the simple steps of installing the Graphical User Interface (GUI) and the Command-Line Interface (CLI) versions.

GUI

Download the Linux installer with the command:

$ wget https://gpt4all.io/installers/gpt4all-installer-linux.run

Make the file executable:

$ chmod u+x gpt4all-installer-linux.run

Run the installer with the command:

$ ./gpt4all-installer-linux.run

By default GPT4ALL is installed to /opt/gpt4all but you can change the installation folder. You’ll see the following dialog box once you’ve specified the installation folder.

GPT4All installer setup

The GPT4All Chat installer decompresses a 3GB LLM model during the installation process which may take time on a slower machine.

On a fresh installation of Ubuntu 23.04 we also needed to install the libxcb-cursor package.

$ sudo apt install libxcb-cursor0

The GUI can then be started from Activities.

CLI

On a fresh installation of Ubuntu 23.04, we first need to install git.

$ sudo apt install git

Next clone the project’s GitHub directory:

$ git clone https://github.com/nomic-ai/gpt4all

Download the 4GB LLM model to the gpt4all/chat directory:

$ cd gpt4all/chat
$ wget https://the-eye.eu/public/AI/models/nomic-ai/gpt4all/gpt4all-lora-quantized.bin

Start the CLI with the command:

$ ./gpt4all-lora-quantized-linux-x86

At least these types of tools will create new jobs — jobs checking the accuracy of the output and fixing it

I think sometimes it also requires libxcb-xinerama0 to be installed on a fresh install of Ubuntu 22.04.

Dear GOD/GODS and/or anyone else who can HELP ME (e.g. TIME TRAVELERS or MEMBERS OF SUPER-INTELLIGENT ALIEN CIVILIZATIONS): The next time I wake up, please change my physical form to that of FINN MCMILLAN formerly of SOUTH NEW BRIGHTON at 8 YEARS OLD and keep it that way FOREVER. I am so sick of this chubby Asian man body! Thank you! – CHAUL JHIN KIM (a.k.a. A DESPERATE SOUL)

Hey Brother,
It downloaded the “bash: ./gpt4all-lora-quantized-linux-x86: No such file or directory”

I have executed this :
OptiPlex-7040:~/Documents/gpt4all/gpt4all/gpt4all-chat$ ./gpt4all-lora-quantized-linux-x86

and it is throwing this:
bash: ./gpt4all-lora-quantized-linux-x86: No such file or directory

Or when I make .bin executable and then run
it again says:
b./gpt4all-lora-quantized.bin: 1: lmgg}: not found
./gpt4all-lora-quantized.bin: 2: Syntax error: “(” unexpected

anyhelp would be appreciated,
Thanks in Advance.
