Strengthening & Weakening Vectors

You can control the AI’s finer focus during a generation by encasing the text you want to emphasize or weaken with { } for strength, and [ ] for weakening.

This works both in the Text Prompt and in the Undesired Content field.

Examples

1girl, black hair, [[[chibi]]], catgirl under a cherry blossom tree

1girl, black hair, chibi, catgirl under a cherry blossom tree

1girl, black hair, {{{chibi}}}, catgirl under a cherry blossom tree

How it works

The weight of AI focus will be multiplied by 1.05 if you enclose the tags or text you want the AI to focus on more with { and }.

The weight of AI focus will be divided by 1.05 if you enclose the tags or text you want the AI to focus on less with [ and ].

Multiple { or [ inside another will multiply the weight each time, so {{ would result in the enclosed part of the prompt being weighted by 1.1025.

Numerical Strengthening & Weakening

Instead of writing like {{{{{this}}}}}, you can specify a numeric emphasis weight by using :: in your prompt. Type the desired weight number directly in front of the :: (e.g. 1.5::) and everything to the right of it will be strengthened by this emphasis weight. To end the strengthened section, just place a :: without a number in front of it. For weakening, you can use numbers between 0.0 and 1.0.

An example prompt could be:

1girl, 1.5::rain, night ::, 0.5::coat ::, black shoes

In this example, rain, night will receive an increased emphasis of 1.5, while coat will be deemphasized to 0.5.

Note: Numerical Emphasis is only available on V4 or higher models.

Negative Numerical Strengthening & Weakening

When using numerical emphasis, it's also possible to input negative values. While it may not be immediately obvious how this could be used, it opens up many possibilities.

Firstly, negative values can often be used as a more effective way of negative prompting. If you have a particular character that usually wears a hat that you want them to take off, often a -1::hat :: can be enough to make it disappear. If that's not enough, you can use a stronger negative value to make it disappear like this: -3::hat ::

However, negative emphasis is not limited to just removing objects from your image. It can also effectively prompt for the opposite of what a tag represents. For example, if you find that your image is lacking color, -1::monochrome :: will usually bring the painter's palette right back. If you find your generated image to be lacking in fine detail, something like -2.5::flat color :: or -6::simple illustration :: can fancy it right up. If your characters end up in a white void, -1::simple background ::, location or something in that vein should help them find their way back to some less ethereal locale.

In many ways, Negative Numerical Emphasis serves a similar role to Undesired Content, but it's not meant to be a general replacement of it either.

Note: Negative Numerical Emphasis is only available on V4.5 or higher models.

Highlight Emphasis

Whether you're using brackets or numerical emphasis, you may notice the colorful highlighting of the prompt box, which quickly lets you see the effects of what you're typing.

If you are not a fan of this highlighting, you can enable or disable the Highlight Emphasis toggle on your Prompt Settings at any time.

Last but not least, if you have the itch to change the colors, you can use the handy color picker to switch up the vibes of the highlights. Simply navigate to the Theme tab in User Settings and go wild!

Note

Technically, every { or ] acts as a x1.05 focus multiplier to everything that's to their right,
and every } or [ acts as a ÷1.05 focus divider to everything that's to their right.
By properly enclosing tags, you essentially apply a multiplication to their focus and then cancel it out.

A good practice is to always close out any strengthening or weakening symbols you use with an equal amount of opposing symbols or a ::, but any complex combination will work according to each symbol's values.

{{1girl, {black hair, chibi,}}} {{catgirl [[under]]}} a {{{{{cherry blossom tree
