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.
