Google Nano Banana 2: Users Report Declining Image Quality

Reddit users are reporting a perceived decline in the quality of Google's AI image generator, Nano Banana 2. Many users describe images as now appearing "flat or cartoonish." What's interesting is that Nano Banana 2 itself hasn't had an official update since February. The AI using it, Gemini, did see an update in July with Gemini 3.6 Flash, but this didn't change the image generator. Despite this, complaints about image quality regressions on Reddit date back to May. One explanation could be that the text model interpreting prompts has changed, even if the image model itself hasn't. This could lead to different image outputs without the core image generator being altered. This matters because it highlights how subtle changes in AI systems can significantly impact user perception and satisfaction.
