Hello

I've been using Generative Fill with Google Nano Banana Pro in Photoshop for photo editing, and it's been extremely unreliable today (February 17, 2026). Yesterday it worked fine, but now it's mostly failing.

I get the error: "Could not complete your request because of a program error" almost every time.

Out of ~50 attempts today, it succeeded only a few times (maybe 3–5), and even then it took much longer than usual to load/complete.

I've burned through around 2000 credits in the process (heavy retries).

Other models in the same dropdown (e.g., Flux, Kontext, or Firefly Pro) work normally and generate quickly/reliably.

In the standalone Firefly web app, Nano Banana Pro generations are also very slow (long progress bars), but they eventually complete after waiting a long time.

What I've already tried (no improvement):
Downgraded Photoshop from 27.3.1 to 27.3
Purged all caches (Edit > Purge > All,
Signed out/in of Creative Cloud.
Tested on different photos/prompts

This feels like a backend/server-side issue specific to Nano Banana Pro (perhaps throttling, quota weirdness after heavy use, or temporary degradation), since other models are unaffected and Firefly web shows similar slowness with it.

Has anyone else seen this spike in failures/slowdowns with Nano Banana Pro recently?

I would really appreciate some response/help.
Thank you

I investigated a lot today, and it happens Google servers for Gemini 3 are saturated, and meeting peak demand. So at times, we may be successful when prompting, but most of the time server scalability is kicking us out. Adobe doesn’t seem to get a reply when the token is used but fails to generate. I browsed and went to the Pablo (trypablo.com) plugin. You have to pay your generations using credits, but as you gain access their custom plan, you may have better results. At least, the last hour was convincing for me after a day of headaches. PS : After discussing with Pablo team, better use their plans than your Google AI/Cloud API key, it works better so far.

Same issue for me as well Nano Banna Pro works 1/20 of the time and even failed generations consume credits.

Same here since a week. NB Pro major issues, failing 95% of time. NB Standard and other models are OK. Really annoying

UPDATE: ChatGPT walked me through getting it to work. I signed out of Creative Cloud and all apps and rebooted the computer and got it to work once everything was signed back in. But then it didn’t work again a few minutes later….so Chat figures it’s capacity throttling or transient errors on the Nano Banana Pro backend. So, we wait.

I am having the same problem, and yes, it is deducting the credits every time I try to generate an image. I have searched everywhere on the Adobe site for a place to complain or get a refund, but cannot find a thing. This is incredibly irritating (and expensive).

18th Feb 18:17 UK - Same problem here, tried 6 gens before and not one completed, problems yesterday also - Better not be deducting credits for this rubbish.

im also facing the same issue. anyone figure out how to fix it ?
hopefully this doesnt effect our credits as my generations are not successfully happening.

it doesn't work in the firefly app...but both firefly and Flux and nano Banana 2.5 works in Photoshop….so it’s a Nano Banana Pro service-side degradation or outage
