Does generative fill in photoshop use Firefly?
Yes. Photoshop's Generative Fill (and Generative Expand) is powered by Adobe Firefly's image model. It's the same commercially safe engine as the Firefly website, wired into Photoshop's selections and layers. On paid plans this standard generation is unlimited and doesn't consume generative credits (as of 2026-07).
Why — the first-principles explanation
Adobe built one generative engine and exposed it in many places. The Firefly website and Photoshop's Generative Fill aren't separate AIs; they're the same Firefly image model behind different front doors. That's why Generative Fill inherits Firefly's core traits.
The first inherited trait is commercial safety. Because the underlying model trained on licensed Adobe Stock and public-domain content, the pixels Generative Fill paints into your image carry the same commercially-safe positioning as Firefly web outputs.
The second is provenance. Content generated by Firefly, including via Generative Fill, is associated with Content Credentials, Adobe's transparency metadata marking AI involvement. So editing a photo with Generative Fill isn't a way to hide AI use.
What Photoshop adds on top is context. Instead of describing a whole scene, you select a region and the Firefly model fills only that area, matching surrounding lighting and perspective, then places results on a non-destructive layer. And because this is standard image generation, paid Firefly and Creative Cloud plans make it unlimited without spending credits, so the same engine that meters credits for video runs free-of-meter for everyday fills.
An example that makes it click
Think of Firefly as one master painter you can hire in different settings. At the Firefly website, you hire them to paint a whole canvas from scratch. In Photoshop's Generative Fill, you hire the exact same painter, but you point at one corner of your existing photo and say "put a tree here." Same artist, same trained skill, just a more focused job.
And because it's the same painter who only studied cleared artwork, the tree they paint is safe to use commercially, and they still sign the back of the photo noting an AI helped, just like on the website.

Does Generative Fill in Photoshop use Firefly? Yes, it does. Adobe built one generative engine and put it behind several doors. The Firefly website and Photoshop's Generative Fill aren't two different AIs, they're the very same Firefly image model. That's why Generative Fill inherits Firefly's key traits. First, commercial safety: because the model trained on licensed Adobe Stock and public-domain content, the pixels it paints into your photo are just as commercially safe as anything from the Firefly website. Second, transparency: content made with Generative Fill is tagged with Content Credentials, so editing with AI isn't a way to hide that AI was used. What Photoshop adds is context. Instead of describing a whole scene, you select a region and Firefly fills just that area, matching the lighting and perspective, and drops it on a new layer so your original is safe. And here's the bonus: because this is standard image generation, it's unlimited on paid plans and doesn't cost you any credits. Same engine that meters credits for video runs meter-free for your everyday fills.
