P: The generative fill in Photoshop 26.0.0 is definitely worse than in previous versions.

I'm currently using version 26.6 , and the Generative Fill AI is absolutely TERRIBLE.  Don't even try to gaslight us otherwise.  In version 25, it looked great.  But last month I decided to finally update to v26.6, and I severely regret it.  
Strangely, even when checking the option to NOT delete my previous Photoshop Versions, it deleted them ALL regardless.  
So now I'm stuck with the HORRIBLE Generative Fill of v26.6.   
How can you actually GET WORSE over time?!!!  
What's even more suspect, is that there's "Adobe Employees" in this thread claiming that this issue has been fixed, which we ALL know is BS.  Nothing has been fixed.  The results are rough and blotchy...resembling more of a cheesy third-party Van Gogh plugin filter from the 1990's.  
What is going on with Adobe?  This Generative Fill in v26.6 is an EPIC FAIL.  
USELESS.  
Instead of gaslighting us, "Adobe Employees", ACTUALLY FIX THE ISSUE.   Mmmkay?

this is so well explained and i totally got it. Thank you. so, as a temporary solution, will install a 25 version just to use for firefly 2

Maybe the solution is to allow us to choose which version of Firefly we want to use instead of having to reinstall an older version? I don't think one size is going to fit all.

My understanding is that despite all the many versions of Photoshop, there are actaully only two working versions of the Gen Fill that Photoshop calls upon. 

Photoshop 2024 (25.x.xx) will call upon Firefly 2 which is more reliable for textures and realistic replacements or filling of gaps, provided you keep areas to be filled under 1024x1024 px. I don't beleive this version is subject to any more server side updates. @MeredithStotzner can you confirm this?

Photoshop 2025 and the current beta (26.x.x) will call upon Firefly 3 which is much worse at textures and really any production work, but may be more relaible for specific object generation. It is definitely more hallucinatory. It also has a few extra features (generate more like this) and ability to add a reference from which to start. It continues to be updated on the server side.

I am wondering, if there is an concensus which prior version produces the best result for gen fill consistently? 

@CMass  The feature works very poorly. None of the 9 generated variants is eligible for use.

@CMass, @MeredithStotzner  

I second this thread. The Generative Fill feature performs terribly. Here's how it “removes” lipstick from an image:

Photoshop v.26.6.0 (Intel based)

macOS 12.7.6

Same. I have been slowly installing prior versions one by one to see which one works better!!! So frustrating!!! 

Confirmed, I thought I was hallucinating but its true Photoshop 2025 gen fill is indeed unusable. I opened up a psd file done in 25.7.0  with the gen layers still there and re-generated with the same prompt in 26.4.1 and what used to look like realistic landscaping looks like roblow now. 

In what language does REMOVE mean fill with another stupid object????!
