Six prompts on Nano Banana 2.1 and Nano Banana 2
Each pair is the first image each model returned for the same prompt, at 1K unless the card says otherwise. Pick a prompt to see both results, and open an image to see it full size.
A vintage travel poster for a mountain town called "Juniper Falls". Big headline "JUNIPER FALLS", a smaller line "Trailheads open · Since 1931", a waterfall between pine ridges at golden hour, flat screen-print style.
Both models spelled both lines correctly. Nano Banana 2.1 kept a classic screen-print look centred on the falls; Nano Banana 2 added a river, cabins and a hiker.

A clean infographic titled "How a Banana Ripens" showing five stages from left to right, labeled "Green", "Breaking", "Yellow", "Spotted" and "Brown", with one short line of text under each stage, flat vector style on a cream background.
The prompt asked for five stages from left to right. Nano Banana 2.1 kept them in one row; Nano Banana 2 wrapped them into two rows. Both spelled all five labels correctly. In this tall 3:4 frame, the single row leaves wide empty space above and below.

A seamless 8:1 panoramic illustration of a harbor town waterfront at dusk: colorful houses, fishing boats, string lights and a continuous hillside skyline from left to right.
Wide 8:1 images at 2K are where Google says 2.1 fixed tiling seams. Nano Banana 2.1 ran as one continuous waterfront. Nano Banana 2 packed in more houses and people, but near its right end a lighthouse repeats and the view jumps, and its boat names are garbled. Open each image to see the full strip.

A character sheet of the same young woman with a short silver bob, round black glasses and a mustard raincoat: front view, side view, back view and a close-up of her face, on a plain white background, with identical features in every view.
Both drew the four views. Nano Banana 2.1 kept the same face, glasses and coat in each and added nothing else. Nano Banana 2 added a name, view labels, a backpack and earrings that the prompt did not ask for.

Place this exact bottle on a wet black slate rock beside a mountain stream in morning mist. Keep the bottle's shape, cap color and label exactly as they are.
Both models got the same uploaded photo of a white bottle with a smooth, pale yellow cap. Nano Banana 2.1 kept that cap and left the original props behind. Nano Banana 2 made the cap brighter yellow and ridged, and carried the eucalyptus sprigs over from the original photo. Pick 2.1 when the product must match the photo exactly.

Close-up photo of an elderly fisherman mending a net on a wooden dock at dawn, weathered hands, natural light, 85mm lens, shallow depth of field.
Both portraits are convincing, with detailed hands and net. Nano Banana 2.1 stayed close on his hands in soft, misty light; Nano Banana 2 pulled back to a wider harbor at sunrise.

What Google changed from Nano Banana 2 to 2.1
Google released Nano Banana 2.1 on October 6, 2026 as an update to Nano Banana 2 (Gemini 3.1 Flash Image), and now recommends it for new projects. According to Google, 2.1 brings better image quality and realism at 1K, 2K and 4K, follows prompts more closely, keeps characters more consistent over several rounds of edits, and renders text and infographic layouts more accurately. It also fixes the tiling seams that very wide or tall images (4:1, 1:4, 8:1 and 1:8) could show at 2K and 4K. Uploads, sizes and aspect ratios are the same on both, as the table above shows. The differences you will notice are how closely each model follows a detailed brief, and the price per image in the table above. That price gap is why Nano Banana 2 is still a sensible choice for quick drafts and everyday images.
