Build Your Own Local LLM: A Guide to GPT4All Setup
Written on
Chapter 1: Introduction to Local LLMs
Did you know that you can operate your own large language model on your local machine without incurring additional costs or requiring advanced graphics hardware? If you're intrigued, this guide will walk you through the steps to set up and leverage your own local LLM. We will also explore various options, draw comparisons between ChatGPT and GPT4All, and outline their respective advantages and disadvantages.
Requirements
To get started, you'll need the following:
- 4–8GB RAM
- Windows OS
- CMake
- MinGw64
You can find all the bindings available for different programming languages in the official open-source GitHub repository. These include:
- C#
- GoLang
- TypeScript
- Python
- Java
The presence of these bindings opens up limitless opportunities for application development. With C#, Java, and GoLang, you can easily support business applications and server-client architectures. TypeScript bindings enable you to host your own LLM on websites, and for data science projects, Python bindings are readily available.
Setup Instructions
As a Microsoft enthusiast (apologies to Linux users!), the following instructions are tailored for the Windows OS. Ensure you adhere to the installation guidelines for MinGw64 and CMake, which are crucial for building the C/C++ backend.
Python Integration
To utilize GPT4All in Python, execute the following command:
pip install gpt4all
This command imports the gpt4all library. Next, you will specify the model and its path. If the model isn't already downloaded, the package will handle that for you. Model sizes range from 3–10GB. After the model is downloaded, you can enter your prompt, defined as shown in the messages. You can choose to stream the results to stdout or receive them in full. The print statement will output the result of your prompt. And that’s it! You’ve successfully utilized your own local large language model.
Comparison of ChatGPT and GPT4All
Various benchmarks for commonsense reasoning and question-answering have been applied to the models in question. For ChatGPT, the reference model used was “text-davinci-003." It's worth noting that OpenAI continuously enhances its models, meaning benchmark scores may not always reflect the latest updates. You can check their official website for an overview. Nevertheless, several models within GPT4All perform comparably to OpenAI's reference in certain areas. However, I must admit that in my experience, the quality of ChatGPT remains unmatched.
Supported Architectures
- Llama
- GPT-J
- MPT
Licensing
Not every model provided is licensed for commercial use. You can easily identify which models are suitable for commercial purposes in the model explorer on the official website.
