Is there an alternative to Generative Fill in Photoshop?

Seam is a Photoshop plugin with the same select-and-describe workflow, but you choose the model (Nano Banana, GPT-Image-2, FLUX.2, Reve, Seedream, or Imagen), set the output resolution up to 4K, and see a cheap draft before the full render. It runs alongside Photoshop's built-in tools rather than replacing them.

Can I use a different AI model for generative fill in Photoshop?

Yes. In Seam's Edit tab the model is a dropdown. Select a region, describe the change, pick the model, and the result comes back masked to your selection on a new layer.

Why is Generative Fill limited in resolution?

The built-in workflow does not expose a resolution setting. In Seam the output resolution is a control: the Nano Banana models render up to 4K, and Preview & Commit lets you judge a small draft before paying for the full render.

Does the edit stay non-destructive?

Yes. The result is placed above the original as a new layer with a layer mask in the shape of your selection, so everything outside the selection stays as it was and the original pixels are never overwritten.

Do I need Photoshop for this?

Yes. Seam is a UXP panel inside Adobe Photoshop 27.0 or newer on Windows and macOS. It is not a separate app.

A Generative Fill alternative, inside Photoshop

The same select-and-describe workflow, with a choice of model, output up to 4K, and a cheap draft before the full render.

Generative Fill is built into Photoshop and is quick for small fixes. Seam's Edit tab works the same way from the outside: select, describe, generate. What changes is what you control in between.

The workflow

Select the area

Any Photoshop selection tool works: lasso, marquee, quick selection. The selection defines what may change.

Describe the change

Write what should be there instead, for example "replace the cup with a red rose". Prompt Enhance expands short prompts for free.

Pick a model

Nano Banana, GPT-Image-2, FLUX.2, Reve, or Seedream, from one dropdown. Different models suit different edits.

Generate

The result arrives above the original as a new layer, with a layer mask in the shape of your selection. The original pixels stay untouched.

What you control

Model choiceNano Banana, GPT-Image-2, FLUX.2, Reve, Seedream, and Imagen under one account

Output resolutionSelectable, up to 4K on the Nano Banana models

Draft firstPreview & Commit renders a small draft for a fraction of the credits; the full render runs on commit

Layer outputA Smart Object by default, masked to the selection

ColorConverted into the document profile: sRGB, Adobe RGB, ProPhoto, or Display P3

ReproducibilityModel, prompt, seed, and settings stored on the layer

RequiresAdobe Photoshop 27.0 or newer, Windows or macOS

Alongside, not instead

Seam is a separate panel. Photoshop's built-in features keep working as before, and you can move between them in the same document. For a criterion by criterion table against the built-in workflow, see the Firefly comparison.
