Face swap puts a portrait face onto another photo. You provide a target image — a person in a scene, pose, or outfit — and APOB swaps in the face of the portrait model you've chosen. In No Model mode, you provide that face separately as a required Reference image. It's the Face swap tab inside Edit Image.
How does Face swap work?
Optionally pick a portrait model on the workstation, then give Face swap the image you want the face to appear in. The first-time hint says: "Upload the image you want to use for the face swap." The result keeps the original photo's pose, lighting, and background but changes the face. When No Model is active, a second Reference image panel appears beside the Base image.
How do I add the image to swap onto?
You have two ways to provide the target ("Base image"):
Select content — choose an existing image from your own media (followed by curated inspiration) or the Community gallery.
Upload image — upload a file from your device.
Before you add an image, the preview area shows "Your reference image will appear here once you select content or upload an image." Once added, it fills the preview.
Which face gets used in the swap?
With a portrait model selected, the face comes from that model, so the extra Reference image panel is hidden and nothing additional is required. In No Model mode, use Select content or Upload image in the required Reference image panel. The Base image is the _destination_; the Reference image supplies the face.
Why is the Generate button greyed out?
Face swap needs a target image — selected content, a remix source, or an uploaded file. No Model mode additionally needs a selected or fully uploaded Reference image; otherwise Generate stays disabled and the app says "Please select or upload a reference image." With a portrait model selected, the Reference image is neither shown nor required. The credit cost is shown next to Generate and depends on your plan. Face swap has no quality option.
How do I remove or replace the image?
Use the delete control on the image to clear it, then add a different one with Select content or Upload image.
What shows on the detail page, and can I Reuse it?
The detail page shows the Base image and, when No Model generation supplied one, the Reference image. Reuse restores both saved inputs. Remix asks you to choose a portrait model, which supplies the identity for the new result. Older records generated before Reference image detail data was saved omit it and require you to select that input again.
What happens if the upload fails?
You'll see "Upload failed" with a Retry button — tap it to try the same file again. APOB recommends using an image generated by APOB for the best results.
On mobile
On mobile the target image fills a large square preview labelled Base image. Tap it to open a bottom sheet with Select content and Upload image options. In No Model mode, the required Reference image card is appended below it with the same selection and upload flow. While an upload runs you'll see a percentage overlay, and a delete button lets you clear the image. A note under the preview recommends an APOB-generated image (or shows an error if the upload failed).
