Object Eraser takes one photo and removes whatever you point at, then fills the gap with background that continues the scene. You point at it two ways: prompt, a short description of what to remove, or mask_url, a black-and-white mask where white marks the area to erase; you can send one or both, and at least one is required. Everything outside the selection comes back exactly as it was, at the original size. It costs $0.03 per output image.

The verdict

It's built for clutter, not for people filling half a frame: a stray object on a table, a sign in the wrong spot, a bystander at the edge of a shot. The bigger the area you erase, the more scene the fill has to invent from nothing, so small and medium objects on a simple background are where this endpoint gives its clearest results.

Use it after a shoot or a generation call to tidy a frame before it goes further: erase a prop that broke the composition, then hand the cleaned photo to Image Expander if you also need a new aspect ratio, or to Image Upscaler before final delivery.

Key facts

  • Price: $0.03 per output image, billed once the edited photo comes back. A description that matches nothing in the photo still returns a result and is still billed.
  • Input: image_url plus prompt, mask_url, or both (at least one required); output_format picks PNG, JPEG or WebP.
  • Output: one edited image per request, at the original width and height, with everything outside the selection unchanged.
  • Sources: the parameter list and the two published examples live on the Object Eraser model page.

What we liked and what held it back

What we liked

  • Two ways to point at the same thing. A short description is enough for an object that's clearly named and located; a mask is the more exact tool when the shape matters or the description would be ambiguous. Sending both narrows the target further.
  • It doesn't touch anything else in the frame. Everything outside the selection returns pixel for pixel as it was, so a small edit doesn't introduce drift elsewhere in the photo.
  • A no-match description doesn't error out. Ask it to remove something that isn't in the photo and it hands back the original, unchanged, rather than failing the request.
  • Output size stays put. The edited image comes back at the same width and height as the source, so it drops straight back into whatever layout the original was built for.
  • Format choice on the way out. PNG, JPEG or WebP on output_format, so the result matches whatever the next step in your pipeline expects without a separate conversion.

What held it back

  • Scale changes the odds. The tool has to invent scene detail to fill the gap, and the bigger the removal, the more it has to invent. A person filling half the frame is a far harder ask than a hand tool on a table, and the fill is more likely to show.
  • A mask has to match the source exactly. Same width and height as the photo, white over what should go, black over what should stay; a mask built for a different crop or a resized copy points at the wrong pixels.
  • A vague description picks the wrong thing, or nothing. Name the object by what it is and where it is when more than one candidate could fit; a bare description with no position is where the removal is most likely to miss.
  • No new object goes in. This endpoint erases and fills with continuation of the existing scene; it doesn't place something new in the gap. That's a separate generation or editing step.
  • A no-op is still billed. If the description matches nothing, you're still charged for a request that made no visible change, so a specific description that clearly matches one object is worth the extra care.

What the edits look like

The model page ships two examples that use the two ways of pointing at a target. The first removes a wooden ladle lying across sauna stones using only a description — "the wooden ladle lying across the sauna stones at the left" — with no mask sent, which is a fair test of whether material and position alone are enough to isolate one object from a textured background. The second clears the edge of a frame with a mask instead: a tall black rack by a window is painted white on a black mask the size of the photo, with no description at all, which is the more reliable approach for thin, structural objects sitting at the border of a shot.

Both cases point at objects, not people, and both sit on backgrounds — sauna stones, a gym window — that the fill can plausibly continue. That combination, a small or medium object on a textured but repeating background, is where this endpoint does its cleanest work.

Prompts that worked

When you erase by description alone, name the material and the position, especially if the photo could hold more than one candidate for a vague description.

1. Removal by description only. From the published sauna example; no mask sent.

Weak: "remove the ladle" gives the tool no position to anchor to if more than one object in the frame could plausibly be a ladle. Strong: the version above, which names the material and the position in one line.

For the frame-edge case — thin, structural clutter like a rack, a pole or a sign at the border of a shot — a mask is the more dependable choice over a description: paint the object white on a black mask the size of the photo and send mask_url with no prompt at all.

Alternatives

  • Need the whole background gone, not one object? Background Remover turns everything behind the main subject transparent instead of filling a small gap.
  • Need a new aspect ratio after cleaning up the frame? Image Expander extends a photo and paints the new area to match.
  • Need the cleaned photo larger before delivery? Image Upscaler enlarges the result to 2K, 4K or 8K afterward.
