Has Generative Fill Model 1 been changed or derated?

Last week it began returning unexpected results when tasked with fixing a small area. I noticed two things:

First: it can’t help but hallucinate. It will reliably return a snake, a bow and arrow, a jar of something or what not. Usually in situations were it used to reliably fill in a texture perfectly and out perform Firefly Fill & Expand.

Second, it seems to have lost the ability to seamlessly retian texture over a small area. Often it comes back mangled or oversharpened if it doesn’t have an ice pick or a toaster thrown in.

Anyone else seeing this? It seemed like a pretty sudden server side thing so please please please don’t ask me to post 10 pages of my system info efectively killing this thread.

I have in the meantime found some old Generative Fill-testfiles from 2023 and, yeah, the results created by Firefly Image 1 in Photoshop 27.9.1 with similar selections do appear different from the old results (though December 2023 would probably have been Photoshop 2024, not sure about the exact iteration of Firefly) in that they tend to pretty much always include some element/s that do not strictly seem necessary or called-for.

Found a simple example I can disclose. Up until the recent past a blank prompt would generate a simple extension of the shape. Now we have some fun filled additions to the party. This is pretty repeatable.

I cannot determine when the change may have happened but it seems evident that »Firefly Image 1 Released October 2023« in Photoshop 2026 is currently performing hugely different from the Firefly version Photoshop utilised in late 2023.

This might merit a Bug Report, but I am unsure about the likelihood of this getting addressed.

Firefly is trained on Adobe Stock. I’ve been looking around the Stock forum, and it seems to be full of AI generated material. What Adobe needs to do, is tighten quality control and stop accepting AI images.

The technical term for this is “model collapse”: https://www.nature.com/articles/s41586-024-07566-y. The net result is a steady downward spiral. AI isn’t getting better, it’s getting worse, and it’s not because of the algorithms. It’s because of the training material.

Out in the world, over 50% of the entire internet is now AI generated.

Much as I love Photoshop - and I do feel it’s getting better and more powerful with every new release - this is one aspect of it that I don’t want any part of. I have disabled all aspects of Firefly and don’t touch it.

I wonder if the guidelines for mandatory disclosure from the European Commission will eventually apply to the rest of the world. It’s a start.

“Marking and labelling of AI-generated content: certain AI-generated or manipulated content must be clearly and visibly labelled and include machine-readable marks.”

I’m seeing why you suspect a server-side change. A sudden change in behavior over the last week, especially when the same type of small selections previously produced clean texture fills, would make me suspicious of a change to the underlying generative service rather than a local Photoshop setting.

Adobe has also recently announced changes to its generative models, including the retirement of Firefly Image 3 from some Generative Fill/Expand workflows, so there have definitely been model-side changes recently.

That said, I don't think we can conclude from this alone that Model 1 has been intentionally derated. The most useful comparison would be to run the exact same image and selection that previously worked well and compare the three generated variations. If all three consistently introduce unrelated objects or damage the surrounding texture, that would be stronger evidence of a model/service change.

If other users are seeing the same behavior with the same type of small texture repairs, I’d be interested to know. That would help distinguish a general model change from an issue specific to a particular image or prompt.

If you give me the repro steps I’ll try it. But in general generative anything is just completely unreliable and I don’t use it. I just tried a few things and got about a 25% success rate.

More to the point though have you experienced a change in the last week or so?

I haven’t noticed a change because I don’t use it except occasionally to see if it’s of any use. I’ve had so many problems with it that I consider it a beta feature and don’t use it.

Could you post screenshots including all pertinent Panels that demonstrate the image, selection, prompt, …?
Are the unintended object present in all three variations?

It would seem strange for Adobe to change an obsolete legacy model as that would negate the point of keeping it available.

Can’t post anything as per disclosure. Yes, they are present always in all three variations repeatedly.

My question is simply, are others experiencing this?

No, I have no such observation – so I should not have posted, I apologise.

The problem with getting a truly informative answer to your original question »Has Generative Fill Model 1 been changed or derated?« is that the Adobe employees that contribute on this Form frequently might not be informed of such goings-on in detail (or at liberty to speak about them publicly).

Maybe you should also post on the Firefly Forum.
