GPT4All

Welcome to the GPT4All documentation LOCAL EDIT

GPT4All is an open-source software ecosystem for anyone to run large language models (LLMs) privately on everyday laptop & desktop computers. No API calls or GPUs required.

The GPT4All Desktop Application is a touchpoint to interact with LLMs and integrate them with your local docs & local data for RAG (retrieval-augmented generation). No coding is required, just install the application, download the models of your choice, and you are ready to use your LLM.

Your local data is yours. GPT4All handles the retrieval privately and on-device to fetch relevant data to support your queries to your LLM.

Nomic AI oversees contributions to GPT4All to ensure quality, security, and maintainability. Additionally, Nomic AI has open-sourced code for training and deploying your own customized LLMs internally.

GPT4All software is optimized to run inference of 3-13 billion parameter large language models on the CPUs of laptops, desktops and servers.

=== "GPT4All Example" py from gpt4all import GPT4All model = GPT4All("orca-mini-3b-gguf2-q4_0.gguf") output = model.generate("The capital of France is ", max_tokens=3) print(output) === "Output" 1. Paris See Python Bindings to use GPT4All.

Navigating the Documentation

In an effort to ensure cross-operating-system and cross-language compatibility, the GPT4All software ecosystem is organized as a monorepo with the following structure:

  • gpt4all-backend: The GPT4All backend maintains and exposes a universal, performance optimized C API for running inference with multi-billion parameter Transformer Decoders. This C API is then bound to any higher level programming language such as C++, Python, Go, etc.
  • gpt4all-bindings: GPT4All bindings contain a variety of high-level programming languages that implement the C API. Each directory is a bound programming language. The CLI is included here, as well.
  • gpt4all-chat: GPT4All Chat is an OS native chat application that runs on macOS, Windows and Linux. It is the easiest way to run local, privacy aware chat assistants on everyday hardware. You can download it on the GPT4All Website and read its source code in the monorepo.

Explore detailed documentation for the backend, bindings and chat client in the sidebar.

Models

The GPT4All software ecosystem is compatible with the following Transformer architectures:

  • Falcon
  • LLaMA (including OpenLLaMA)
  • MPT (including Replit)
  • GPT-J

You can find an exhaustive list of supported models on the website or in the models directory

GPT4All models are artifacts produced through a process known as neural network quantization. A multi-billion parameter Transformer Decoder usually takes 30+ GB of VRAM to execute a forward pass. Most people do not have such a powerful computer or access to GPU hardware. By running trained LLMs through quantization algorithms, some GPT4All models can run on your laptop using only 4-8GB of RAM enabling their wide-spread usage. Bigger models might still require more RAM, however.

Any model trained with one of these architectures can be quantized and run locally with all GPT4All bindings and in the chat client. You can add new variants by contributing to the gpt4all-backend.

Frequently Asked Questions

Find answers to frequently asked questions by searching the Github issues or in the documentation FAQ.

Getting the most of your local LLM

Inference Speed of a local LLM depends on two factors: model size and the number of tokens given as input. It is not advised to prompt local LLMs with large chunks of context as their inference speed will heavily degrade. You will likely want to run GPT4All models on GPU if you would like to utilize context windows larger than 750 tokens. Native GPU support for GPT4All models is planned.

Inference Performance: Which model is best? That question depends on your use-case. The ability of an LLM to faithfully follow instructions is conditioned on the quantity and diversity of the pre-training data it trained on and the diversity, quality and factuality of the data the LLM was fine-tuned on. A goal of GPT4All is to bring the most powerful local assistant model to your desktop and Nomic AI is actively working on efforts to improve their performance and quality.
