Thanks :) !

1. Download the vocab.json and find some way to sample it : https://huggingface.co/runwayml/stable-diffusion-v1-5/raw/main/tokenizer/vocab.json

Note that the vocab.json is badly configured for emoji symbols. They read as a garbled mess like ĮãĤĬãģŁãģĦ

Ignore those.

Instead use emojis in prompt. Find some ways to sample these as well : https://perchance.org/fusion-t2i-emojis-2

All unicode symbols (not required , but can be fun to see what weird stuff you can create with these symbols) : https://perchance.org/fusion-t2i-unicode-2

You can try entering some words/emojis in this SD tokenizer , and you will see that they match the vocab.json list : https://sd-tokenizer.rocker.boo/

2. Divide vocab.json list two categories:

Suffix tokens = tokens that end with , which represents whitespace. Like "banana " .

Prefix tokens = tokens without whitespace. Like "post" used in words like "postapocaplypse " or "postman "

Prefix tokens give properties to suffix tokens when placed in front of them.

3. If you have a means to invoke random prefix- , suffix- and emoji- tokens you can now mix them to create crazy results

I recommend using Notepad++ to sort the tokens.

4. Follow the cross attention rule: "SD reads the prompt left to right , one token at a time, finding association from the previous token to the current token (and the inage rendered thus far)"

You can try the -prefix . -suffix and the emoji-tokens out on the fusion generator if you like (I'm the dev) : https://perchance.org/fusion-ai-image-generator

There are also other datasets there which you may find useful.

There is a tutorial at the top, but its kinda wordy and haphazard.

I recently wrote a guide on Fusion Generator Discord for NSFW stuff : https://discord.gg/j6qAX3MWub

You can also find savefiles posted there with example prompts which can be loaded into the fusion-generator

I don't want to present it as a "how to prompt" guide since there is no correct way to prompt things.

It's more a way to show users that there are more options available to them , should they wish to use them.
