High level instructions for getting GPT4All working on MacOS with LLaMACPP

See nomic-ai/gpt4all for canonical source.

Environment

• This walkthrough assumes you have created a folder called ~/GPT4All. Adjust the following commands as necessary for your own environment.
• It's highly advised that you have a sensible python virtual environment. A conda config is included below for simplicity. Install it with conda env create -f conda-macos-arm64.yaml and then use with conda activate gpt4all.

Download the 4bit Quantitized Model

Put the downloaded file into ~/GPT4All/input

Available sources for this:

Safe Version:

• Direct Link
• Torrent-Magnet

Unsafe Version: (This model had all refusal to answer responses removed from training.)

• Direct Link
• Torrent-Magnet

Get the Original LLaMA models

Put the downloaded files into ~/GPT4All/LLaMA

Convert GPT4All model

Get the pre-reqs and ensure folder structure exists.

python -m pip install pyllamacpp
mkdir -p `~/GPT4All/{input,output}`

Convert the input model to LLaMACPP

  ~/GPT4All/input/gpt4all-lora-quantized.bin \
  ~/GPT4All/LLaMA/tokenizer.model \
  ~/GPT4All/output/gpt4all-lora-q-converted.bin
