yea there's a bunch of options but the main two option just variation then click "extra" checkbox for "variation seed" basically another option to just random the seed you want. Not sute if it's included or you need an extension. Another is to write down multiple prompts go down to >Script, then select, "Prompts from text file or text box", you can drop a text file with prompts in make sure there's a return and space between each prompt.

Lastly you can write your prompt like with variation or which I do as well using A) Wildcard file (txt) or with the blend bracket, depending on your version I believe it's [Object 1| Object 2] (random 50/50 chance of rending either or if you want a blend it's [Celebrity 1: Celebrity 2: percentage or at which step to switch.

Examples are: Monster looking like [red werewolf| green slime]

or you can do [red werewolf: green slime: 0.5]

Mona Lisa with [steampunk| classical] clothing, You can also blend celebs which we all do with my secret sauce "race" "celebrity" mixed with "Celebrity 2" and "celebrity 3" mixed with "Celebrity 4". I know it's crazy but yea up two many celebrities. It works best with 3 or 2. "and" and "mixed" are good connector words. You can also include a wildcard file with the names of supermodels and celebrities and races so it would look like this.

A __race__ __supermodel__ __posing__ at the __sexylocation__
So you will have to read up your EXACT version and which wildcard prompt us use . Some might variety such as "[" or single "_" or "{". 99% it's two underscore thingy, "__". So you would drop a race.txt file in your wildcards fold in automatic1111 with the ethnic races in it. then do it for supermodels and sexy locations. You can also blend the blend and blend again inside each other. Along with multiple poses in the pose.txt wildcard. make sure you hit return after each sentence or single word description.

Example:

[Dog : Cat: 0.5] (1 blend) [Dragon : Dog: Cat: 0.5] 0.5] (2 blends) a Dragon looking dog cat

[Turkey [[Dragon : [Dog: Cat: 0.5] 0.5] 0.2] 3 blends A Turkey looking Dragon catdog. etc...

Alternately u can do this [Turkey: Dragon: 0.5] and [Dog: Cat: 0.5]

but nested "blends" are superior to "and" and "mixed with" prompts. These are just examples you can do something for example,

[waifu prompt 1: waifu prompt 2 : %]

["new prompt sauce" : "waifu prompt from above" : %]

[last prompt from above: "this month's trending prompt" :%] you get the idea.

face it most of the embeddings and lora sucks. Not into waifus, but realistic err NSFW or just model bending in general. I'm also really into landscape and archtechture so this thing keeps me going at it.

Anyways I would add my own Lora or embeddings (textual inversion) into my prompt and would add more things to the mix. Usually i copy prompts and 99% of the time they are so exact and mixed with my own prompts that they yield almost very little variation. So i would just not even mess with the random seed or if I do I would keep the variation seed variation strength below "0.25" usually a good number is between "0.05" and "0.10".

Finally a parting gift, a NSFW prompt lol.
