NextStep 1 Large Edit
NextStep 1 Large Edit adapts the NextStep image pipeline to an input image and an editing instruction. Its example combines an image marker with changes to objects, background and text.
Keep the source image in the request
The published inference path supplies both the reference image and the requested edit. This differs from the text-to-image release that begins without an image.StepFun NextStep-1-Large-Edit model card
Check regions that should stay fixed
Practical guidance. An edit can satisfy the instruction while changing unrelated details. Compare faces, signs and backgrounds outside the target area. Use a focused instruction when one change is sufficient.
