// how it works

How it works

  1. Install the desktop app

    Download the free installer for Windows, macOS or Linux from nomic.ai/gpt4all.

  2. Download a model

    In the app, open the model browser and pick one that fits your RAM — the catalogue shows sizes and requirements; downloads are a few GB each.

  3. Chat — or chat with your documents

    Start chatting fully offline, or add a folder under LocalDocs to ask questions about your own files with local retrieval.

Why people love it

Runs on plain CPUs

Quantised GGUF models run usefully on ordinary laptops — no GPU required, which is the whole point.

A real desktop client

Model browser, chat UI and settings in one free app; nothing to configure in a terminal.

LocalDocs

Point it at document folders and chat with their contents using retrieval that never leaves the machine.

SDKs and server mode

Python and Node bindings, plus an OpenAI-style local server, for building on the same models.

// run it

Run it yourself

  1. Desktop installer

    The route most people take — one download, then pick a model in-app.

    https://nomic.ai/gpt4all
  2. Python SDK

    From the README: install the bindings and load a model in a few lines.

    pip install gpt4all
    
    from gpt4all import GPT4All
    model = GPT4All("Meta-Llama-3-8B-Instruct.Q4_0.gguf")
    with model.chat_session():
        print(model.generate("How can I run LLMs efficiently on my laptop?", max_tokens=1024))
  3. Local server

    The desktop app can serve an OpenAI-compatible API on your machine for other tools to use.

Questions, answered

Who makes GPT4All?

Nomic AI (nomic-ai/gpt4all on GitHub), the company behind the Atlas data tool.

Is GPT4All free?

Yes — the app, SDKs and ecosystem are MIT licensed and free for commercial use. The models you download carry their own licences — check each one.

Do I need a graphics card?

No. GPT4All is built for CPU inference with quantised models; a GPU speeds things up where supported, but a modern laptop is enough.

How does it compare to a well-known alternative?

Against Ollama, GPT4All gives non-technical users a full graphical app and document chat out of the box, while Ollama is CLI-first and stronger as a developer server. Against LM Studio, the difference is licensing and openness: GPT4All is MIT open source, LM Studio is a polished free-but-closed app.

How do I get started?

Install the desktop app, download a recommended model from the in-app browser, and chat — offline from the first message.
