PromptScript: Pseudo-Language for Prompting Language Models.

One of the hardest things about working with language models, especially for those of us who have English as a second language, is that they can be difficult to prompt in a way that allows them to achieve their peak performance.

This is particularly true when it comes to conditional logic or prompts that need to potentially override the default behavior of the model.

Below, I'm going to provide some examples of a Pseudo-Language that I've used with great success with Claude 2 and 3, GPT-3 and 4, as well as numerous open, free-to-use models.

FOR <variable> = <start> TO <end>

Simple NSFW Refusal Prompt

This, in theory, works with the latest "staging" version of SillyTavern.
Of course you will need to add quite a bit more of the same sauce to make the output match your desired style.
