gpt4all-chat

Cross platform Qt based GUI for GPT4All versions with GPT-J as the base model. NOTE: The model seen in the screenshot is actually a preview of a new training run for GPT4All based on GPT-J. The GPT4All project is busy at work getting ready to release this model including installers for all three major OS's. In the meantime, you can try this UI out with the original GPT-J model by following build instructions below.

Features

Cross-platform (Linux, Windows, MacOSX)
Fast CPU based inference using ggml for GPT-J based models
The UI is made to look and feel like you've come to expect from a chatty gpt
Check for updates so you can alway stay fresh with latest models
Easy to install with precompiled binaries available for all three major desktop platforms
Multi-modal - Ability to load more than one model and switch between them
Supports both llama.cpp and gptj.cpp style models
Model downloader in GUI featuring many popular open source models
Settings dialog to change temp, top_p, top_k, threads, etc

Check for updates to get the very latest GUI

Feature wishlist

Multi-chat - a list of current and past chats and the ability to save/delete/export and switch between
Text to speech - have the AI response with voice
Speech to text - give the prompt with your voice
Python bindings
Typescript bindings
Plugin support for langchain other developer tools
Save your prompt/responses to disk
Upload prompt/respones manually/automatically to nomic.ai to aid future training runs

Building and running

Install Qt 6.x for your platform https://doc.qt.io/qt-6/get-and-install-qt.html
Install cmake for your platform https://cmake.org/install/
Download https://huggingface.co/EleutherAI/gpt-j-6b
Clone this repo and build

git clone https://github.com/ggerganov/ggml.git
cd ggml
mkdir build
cd build
cmake ..
cmake --build . --parallel
python3 ../ggml/examples/gpt-j/convert-h5-to-ggml.py /path/to/your/local/copy/of/EleutherAI/gpt-j-6B 0
./bin/gpt-j-quantize /path/to/your/local/copy/of/EleutherAI/gpt-j-6B/ggml-model-f32.bin ./ggml-model-q4_0.bin 2

and then

git clone --recurse-submodules https://github.com/nomic-ai/gpt4all-chat
cd gpt4all-chat
mkdir build
cd build
cmake ..
cmake --build . --parallel
mv /path/to/ggml-model-q4_0.bin bin
./bin/chat

To get Qt installed for your system

Highly advise using the official Qt online open source installer.
You can obtain this by creating an account on qt.io and downloading the installer.
You should get latest Qt {Qt 6.5.x} for your system and the developer tools including QtCreator, cmake, ninja.
WINDOWS NOTE: you need to use the mingw64 toolchain and not msvc
ALL PLATFORMS NOTE: the installer has options for lots of different targets which will add a lot of download overhead. You can deselect webassembly target, android, sources, etc to save space on your disk.
