•required

Prompt that guides image generation.

•required image_url
Drop a file, or

Provide the generation source as an image URL, ensuring that the source image and mask have identical dimensions.

Advanced negative_prompt · output_format · guidance_scale · num_inference_steps · seed · enable_thinking_mode · enable_reflection_mode · enable_safety_checker
default

Negative prompt specifying image details to exclude, including colors, objects, scenery, or finer features. Examples include a moustache, blur, or low resolution.

output_format default jpeg

File format for the resulting image.

default 6

True CFG scale governing the model's degree of prompt adherence.

default 50

Inference step count; 50 is recommended.

Seed for reproducible images: an identical prompt and seed produce an identical image when the model version is unchanged.

About Stepx Edit2

Edits the picture at `image_url` following a `prompt`. `enable_thinking_mode` uses a multimodal language model to interpret abstract instructions, and `enable_reflection_mode` reviews the result and corrects unintended changes. The response can include `reformat_prompt`, `think_info` and `best_info`. Steps go up to 100 (default 50), and output is jpeg or png.

Parameters

Send either the canonical name or the native name, not both. Canonical names

Same shape on every modeltype, url, content_type, width, height and duration, for images, video and audio alike. output is the model’s own result object.
Fields of output
images
array of object {url, width, height, content_type}Images produced by the model.
timings
object
seed
integerImage-generation seed, including the randomly chosen value if the input omitted a seed; otherwise, it repeats the supplied value.
has_nsfw_concepts
array of booleanIndicates whether NSFW concepts appear in the generated images.
prompt
stringPrompt used during image generation.
reformat_prompt
string | nullWith thinking mode enabled, the response includes how the model understood your instruction; otherwise, this interpretation is unavailable.
think_info
array of string | nullDetails of the reasoning process, available only with thinking mode enabled.
best_info
array of object | nullAnalysis from reflection, available only with reflection mode enabled.
