‘Now, almost every image looks flat or cartoonish’: I saw Reddit arguing that Google’s AI image generator had got worse — so I ran my own comparison against ChatGPT

Can an AI image generator get worse? Or is something else going on here…

Looking through a recent thread on Reddit comparing images created with the same prompt on Nano Banana 2 and ChatGPT, I noticed an interesting trend — users seem to think that Nano Banana 2 has actually gotten worse over time.

“Nano 2 had a serious downgrade” said one user, with another replying “Yea I'm a Pro user, and the image quality seems to have been downgraded a lot. Now, almost every image looks flat or cartoonish, no matter how detailed my prompt is. It honestly feels like Google intentionally lowered the model's performance.”

A downgrade seems like a bit of a stretch to me. For a start, Nano Banana hasn’t officially been updated since February, or at least there hasn’t been a public announcement of a change.

The last update to Gemini (the AI which uses Nano Banana 2) was in July when Google released Gemini 3.6 Flash. It also updated the Gemini app's underlying model selection and orchestration, but it didn’t change the image generator.

Interestingly, once I started looking through Reddit threads I found complaints about Nano Banana 2 quality regressions dating back to May, well before the recent Gemini 3.6 Flash announcement, suggesting some users have perceived changes over time.

That doesn't prove a regression, but it does suggest this isn't a brand-new observation.

Google Earth integration

Google did release a new image model, Nano Banana 2 Lite, at the start of July. And more recently, Google has been integrating Nano Banana 2 into products like Google Earth, then temporarily pulling one of those features after misuse, but there's no indication that the underlying image model itself was updated as part of any of these releases.
