A prompt box that changes on every run. Choices in curly brackets are picked on the server from the wired seed, so the same seed gives the same prompt again and a randomized seed with a run count of 50 gives 50 mixes. Brackets without a | are left alone, so JSON prompts pass through.

# Prompt Variations
|
|
|
|
A prompt box that changes on every run. Write choices in curly brackets and
|
|
the node picks one from each set:
|
|
|
|
```text
|
|
A woman in a {plain|striped|patterned} {tank top|sweater|button-up shirt}
|
|
and {jeans|a pleated skirt|cargo shorts}, {standing|sitting on a stool|leaning on the wall}.
|
|
```
|
|
|
|
One run might give "A woman in a striped sweater and jeans, sitting on a
|
|
stool." The next gives another mix.
|
|
|
|
Use it to make many different pictures in one go. Wire in the seed, set the
|
|
Seed node to **randomize**, and set the number of runs next to the Run
|
|
button to 50. Each run gets a new seed, so each picture gets new choices.
|
|
|
|
## Controls
|
|
|
|
- The text box (`text`): your prompt. Put each set of choices in curly
|
|
brackets and split the choices with `|`. Write as many sets as you like,
|
|
each with as many choices as you like.
|
|
- `seed` (a socket): the seed your sampler uses. A new seed picks new
|
|
choices. The same seed picks the same ones again, so a picture you like
|
|
can be made again from its seed.
|
|
|
|
## Output
|
|
|
|
- **prompt**: your text with one choice picked from each set. Wire it to
|
|
Show Text to see what was picked.
|
|
|
|
## Tips
|
|
|
|
- An empty choice lets a part come and go: `a {|striped} shirt` gives "a
|
|
shirt" or "a striped shirt".
|
|
- Sets can go inside sets: `{a {red|blue} hat|a scarf}`.
|
|
- Text without curly brackets comes out exactly as typed.
|
|
- To make one choice come up more often, write it more than once:
|
|
`{jeans|jeans|skirt}`.
|
|
|
|
## Technical details
|
|
|
|
Only brackets that hold a `|` are choices. Brackets without one are left as
|
|
they are, so a JSON prompt such as `{"light": "soft"}` passes through
|
|
unchanged. A `|` inside JSON brackets still counts as a choice.
|
|
|
|
The innermost sets are picked first, from left to right, with Python's
|
|
`random.Random(seed)`. The same text and seed always give the same prompt,
|
|
on any machine. Spaces around each choice are trimmed, and an empty pick
|
|
also drops the one space in front of it.
|
|
|
|
The picks happen when the prompt runs, on the server, not in the browser.
|
|
ComfyUI's own `{a|b}` choices in some text boxes are picked by the browser
|
|
when you queue, with no seed; this node does not use them.
