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

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
• Multi-modal - Ability to load more than one model and switch between them
• 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
• Syntax highlighting support for programming languages, etc.
• REST API with a built-in webserver in the chat gui itself with a headless operation mode as well
• Advanced settings for changing temperature, topk, etc. (DONE)

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 --recurse-submodules https://github.com/nomic-ai/gpt4all-chat
cd gpt4all-chat
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
./chat

Building and running CLI tools only (no Qt required)

• Install cmake for your platform https://cmake.org/install/
• Clone this repo and build the ggml subfolder

git clone --recurse-submodules https://github.com/nomic-ai/gpt4all-chat
cd gpt4all-chat/ggml
mkdir build
cd build
cmake ..
cmake --build . --parallel
wget https://gpt4all.io/models/ggml-gpt4all-j.bin # Download GGML model if required
./bin/gpt-j -m ggml-gpt4all-j.bin -n 200 --top_k 40 --top_p 0.9 -b 9 --temp 0.9 -p "Below is an instruction that describes a task. Write a response that appropriately completes the request.

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.

• Pull requests welcome. See the feature wish list for ideas :)
