# 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 the original
a preview of a new training run for GPT4All based on GPT-J. The GPT4All 
project is busy at work training a new version with GPT-J as the base, 
but it isn't ready yet. In the meantime, you can try this UI out with the
original GPT-J model. Full instructions for how are included below.

## Features

* Cross-platform (Linux, Windows, MacOSX, iOS, Android, Embedded Linux, QNX)
* 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
* Easy to install... The plan is to create precompiled binaries for major platforms with easy installer including model
* WORK IN PROGRESS!!
