Google's newest image model is cheaper and faster than its premium one, and it wins Google's own preference tests. Here's when 2.1 is enough and when Pro is still worth paying for.

By the Rizz AI team · Updated October 21, 2026

In short

Use Nano Banana 2.1 for almost everything. It beats Nano Banana Pro in Google's preference tests (1050 vs 935), renders text more accurately, makes images in about 25 seconds instead of 40, and costs roughly a quarter as much per image.

Pick Nano Banana Pro for a single premium image where extra photographic detail matters more than speed or price.

Which makes better images?

On paper, Nano Banana 2.1 wins. Google's published preference score for text-to-image is 1050 for 2.1 against 935 for Pro, and 2.1 is ahead on keeping the same character consistent across edits (1106 vs 1011).

In practice, reviewers still find Pro produces noticeably richer detail on complex scenes: busy compositions, exact brand assets or scenes that rely on world knowledge. For selfies, portraits, profile pictures and social posts, that difference rarely shows, and 2.1's speed makes it easier to try several looks.

Which keeps my face the same?

Both models keep a face recognizable when the input is good. What matters more than the model:

A sharp, well-lit, front-facing photo with no sunglasses or heavy filters.
Saying "keep the face exactly the same" in the prompt.
Changing one thing at a time with follow-up edits instead of rewriting everything.

Nano Banana 2.1 is better at keeping the same person consistent over several edits in one conversation, which helps when you're building a set of photos.
