Characters First
Portrait or full body, by ratio
ratio accepts 1:1 (default), 3:4, 2:3, 9:16, 4:3, 3:2 and 16:9. Tall ratios such as 2:3 or 9:16 leave room for full-body poses; 1:1 and 3:4 suit avatar crops.
Steer with a negative prompt
Up to 2,000 characters in prompt and another 2,000 in negative_prompt for what to keep out of the image. If you omit negative_prompt, a sensible default is applied.
Repeatable results with seed
seed defaults to -1 for a random result. Pass a non-negative integer to reproduce a previous generation, then vary only the prompt to make controlled changes to the same character.
A short request: model and prompt are required, three fields are optional.
