How to Prep The Jax
Getting the AI write in the format you want it to write.
As GPT-J is not finetuned yet, it really wants to mimic the way you write and output something similar. As a result, if you want to have the AI write in a specific way without the use of Authors Notes, which don't work too well due to the format, you can prep the AI beforehand.
To prep the AI, find a snippet of text you'd like it to mimic, for this example I picked the poetry of Edgar Allen Poe.
You don't need the entire thing, just enough so that the AI has an idea of how the formatting will work. The more you have the better idea it will have, but the higher chance that it will bleed into your story. For example, it'd bring up the name Lenore a lot early on in my example.
Use this as your starting prompt and disable Always Add Prompt. I find that with GPT-J you don't really need this anyways as it doesn't have Alzheimer's like Dragon does.
Let it generate the prompt, then when done, replace the output with a newline and the start to your story which will act as the actual prompt.
GPT-J seems very sensitive to newlines, starting an entirely new train of thought when it sees one, which helps here.
At this point, there's enough context for the AI to generate in the style of the snippet you picked. Here's what it generated for me, with no handholding.
