The composer prepares your next request. The run history below it shows earlier requests and their results.

How to use it

Area	What it controls
Source thumbnail	The preset or image guiding your next request
Person	Whose face should appear
Prompt and reference chips	What to create and which supporting images to use
Options	Action, face, clothing, text and other generation settings
Variation selector	How many images to request in one run
Run history	Earlier prompts, settings and results

Prepare the next request in the composer above the history. Open an existing result to inspect it without generating another image.

What happens

The composer is editable working state; each run is a separate historical request. A variation is one output inside a run. Selecting a tile for comparison is different from selecting it as your next source.

Example

Situation: you have already generated runs 1 and 2 with different presets.

After choosing Reuse this run on run 1	Result
Composer settings	Replaced with run 1’s stored settings
Previously generated run 2	Still available in the history
Unsent composer edits	Replaced; review them before reusing a run

Good to know

Before generating after a reuse action, check the source, person, prompt and number of variations. Reuse run, Regenerate and Use as source have different effects.
