Google’s new Nano Banana Pro uses Gemini 3 power to generate more realistic AI images

Detecting less sloppy slop

Google is not just blowing smoke—the new image generator is much better. Its grasp of the world and the nuance of language is apparent, producing much more realistic results. Even before this, AI images were getting so good that it could be hard to spot them at a glance. Gone are the days when you could just count fingers to identify AI. Google is making an effort to help identify AI content, though.

Images generated with Nano Banana Pro continue to have embedded SynthID watermarks that Google’s tools can detect. The company is also adding more C2PA metadata to further label AI images. The Gemini app is part of this effort, too. Starting now, you can upload an image and ask something like “Is this AI?” The app won’t detect just any old AI image, but it will tell you if it’s a product of Google AI by checking for SynthID.

At the same time, Google is making it slightly harder for people to know an image was generated with AI. Operating with the knowledge that professionals may want to generate images with Nano Banana Pro, Google has removed the visible watermark from images for AI Ultra subscribers. These images still have SynthID, but only the lower tiers have the Gemini twinkle in the corner.

While everyone can access the new Nano Banana Pro today, AI Ultra subscribers will enjoy the highest usage limits. Gemini Pro users will get a bit less access, and free users will get the lowest limits before being booted down to the non-pro version.
