Nano Banana 2.1 Is Out. Your Photo Booths Already Run It.

Same day, every booth

Google released Nano Banana 2.1 on 6 October 2026. By the evening, every photo booth on the Nano Banana mode was running it. No update to install, no setting to change, no email to wait for. If your booth ran Nano Banana 2 at lunch, it ran Nano Banana 2.1 at dinner.

Price and speed stay where they were: 1 credit per photo, about 15 seconds from selfie to result. The mode is now listed as Live Edit Nano Banana 2.1 in your dashboard. Nano Banana Pro stays as it is, for the sharpest output.

What Google changed

Nano Banana 2.1 is Google’s update to Nano Banana 2, the model behind the Nano Banana mode since February. In its own words, the model “outperforms our previous models across the board, with notable leaps in visual design, mask-based editing, and subject consistency”. The details are on the Nano Banana 2.1 model card and the Gemini API model page.

For a photo booth, four of those changes matter:

Likeness. Faces hold closer to the selfie, and the gain is largest on groups. On Google’s own editing benchmark, multi-character consistency goes from 978 to 1106 Elo between Nano Banana 2 and 2.1.
Text that reads. Brand names, signs and logos in the scene come out clean, so a sponsor banner behind the guest no longer needs a second take.
Groups. The model takes up to 14 reference images and keeps up to four people consistent in one picture. Four friends, four recognisable faces.
Wide formats. Panoramic and strip layouts no longer show seams where the model stitched the scene.

Google also retires Nano Banana 2 on 29 October 2026. Your booths moved three weeks early, so that date is not yours to worry about.

What changes for you

Nothing, by design. Your prompts, styles, templates and delivery settings run as they are. Product images for product placement work as before. The Windows kiosk and the tablet app picked the new model up on the next photo without a restart.

One honest note: if a style was tuned around a quirk of the old model, run it once and look. Models change, and a prompt that was fighting Nano Banana 2 may now be pushing in the wrong direction.

How we did it

We tested the model on staging in the afternoon, then ran it on a production booth and looked at the result before touching anyone else’s. Same credit, same tokens, same speed, better photo. Then we switched every booth in one database migration and sent one email to every account. The whole thing took an evening.

That is the reason we keep our own connectors to each model provider rather than a middleman: when Google ships, you get it the same day, with the same automatic backup route to a second provider in case the first has a bad minute at your event.

Pick your engine

Nano Banana 2.1 is one of four photo engines in AI Photobooth, and the choice is yours per booth:

Nano Banana 2.1 for speed and likeness on any volume of guests.
Nano Banana Pro for the sharpest faces when the queue allows an extra few seconds.
GPT Image 2.5 when you want OpenAI’s take on the same prompt.
FLUX.3 for signs, posters and rich scenes.

If you have not tried Nano Banana since the update, open a booth, take a selfie and compare it with one from last week. Then reply to the email we sent you if anything looks off: we check every report the same day.
