Google released Nano Banana 2.1 on October 6, 2026, saying it improves image generation and editing across the board. It is the company's first major update to its image model since February 2026, when Nano Banana 2 was introduced.
Google reported 1K image costs of 3.36 cents, measured on the standard pricing model, that compares with 6.70 cents for Nano Banana 2. Nano Banana 2.1 also reduces 4K image costs from 15.10 to 7.56 cents.
Nano Banana 2.1 is built on Gemini 3.6 Flash and targets users seeking efficient image generation. Availability begins with the model rolling out across Google's products, initially for developers and businesses.
"Widescreen 16:9, a hyper-realistic DSLR photo. A monkey holding a pink banana is sitting on a tiger in the foreground.
In the background, a HORSE is RIDING AN ASTRONAUT. The astronaut is underneath, like a living 'spacesuit horse saddle,' and the HORSE is clearly on top, in control, as the rider.
Make it 100% unambiguous: the HORSE is the rider and the ASTRONAUT is being ridden—NOT the other way around. High-resolution, sharp focus, realistic lighting," said Matthias Bastian, the author of the article.
The model performs well in complex scenarios but struggles with scale, making the horse look more like a pony.
The announcement follows Google's earlier release of Nano Banana 2 and the Gemini 3.1 Flash Image model. Google described Nano Banana 2.1 as the more efficient counterpart to its Pro model, which still produces more realistic and natural images in practice.
Google did not say when the previous model, "gemini-3.1-flash-image," will be fully phased out, and it raised the open question of whether Nano Banana 2.1 can fully replace the Pro model. The model is already rolling out across Google's products, including the Gemini app and Google Search.
