NAI3 is NovelAI’s image generation model. The style is rather limited, you can only generate flat-style anime images.
Remember, curly braces add emphasis to a particular word or phrase in NAI, and you can use multiple sets like so: {{{ cum }}}
Square braces de-emphasize a word like so: [[ face ]] (note: that doesn’t not mean you don’t want this word. It just de-prioritizes it relative to the other words in your prompt.
