The naming is confusing and evil.
1. This is not based on GPT4. If you're going to include the words "GPT4" in your name and not base it on GPT4, what else can I not trust you about?
2. There's no direct link to the actual model used, just a reference to GPT-J.
3. I searched for GPT-J, huggingface docs describes it as a GPT-2-like model, the repo for it was started in august 2021, and hasn't really had significant updates in a long while.
Honestly, I don't want to spend time figuring out if this is worth it, trust is already out the window.
It's made by the same people here https://github.com/nomic-ai/gpt4all who initially distributed a LLaMA based model finetuned for conversations over torrent. I think you're overly critical. GPT4All naming is fine in my opinion, it's literally "GPT for all", but I can see why people would dislike it.
