Nano Banana 2.1 AI Image Generator

Every image below was generated on 8 October 2026, first take, with the exact prompt shown.

Text and infographics, right at 1K

We reran the poster, infographic and Korean exhibition prompts from the Nano Banana Pro page unchanged. All three were correct: the NIGHT MARKET headline and its em-dash subtitle, all four stages of the heat-pump cycle with a caption under each, and every syllable block of 「고요한 흙」. Each took 24 to 28 seconds at 1K. One caveat: on the Korean poster it added an exhibition date and a gallery name we never asked for — with the year set to 2024. Read what it writes, not just what you asked for.

The same face through two rounds of edits

We generated a portrait, then changed her clothes and moved her to a fish market, then moved that result to a rainy street at night. Across both rounds the face, the short auburn curls, the freckles and the small silver hoop stayed the same person — the thing that usually drifts first when you edit an edit. It was looser about the rest: the second round kept the coffee cup from round one without being told to, and it ignored "looks over her shoulder" and had her face the camera.

4K wide shots without repeated tiles

Wide, high-resolution frames are where image models tend to repeat a texture or leave a visible join, and this is the fix the update claims. Our one 4K 16:9 test — a lighthouse keeper on a cliff path at dawn — came back at 5504×3072 in 45 seconds, and at full size we found no tiling: the fog, cliffs and grass change continuously across the frame. One image is not a benchmark, but it is the result we got.

Where it failed: an 8:1 banner

We asked for a continuous Mediterranean harbour panorama with SUMMER IN LIGURIA set in the left third. The 5856×704 result has clear vertical joins where the scene restarts, and the headline is a smear of letter-like shapes. On the Nano Banana 2 page, the same 8:1 format came back as one continuous panorama in our August tests. For extreme banners, use Nano Banana 2; use 2.1 at ordinary ratios.

• Anyone making posters, menus and infographics

  Headlines, subtitles and diagram labels came back correctly spelled at 1K in under 30 seconds. Proofread the result — it can add lines you did not ask for.

• People editing the same person repeatedly

  Change the outfit, then the location, then the light: in our two-round test the face stayed the same person each time.

• Wide and high-resolution work

  A 4K tier at 130 credits, and a 16:9 4K test with no repeated tiles.

• Not for: 8:1 and 1:8 banners

  Our 8:1 test split into panels with an unreadable headline. Nano Banana 2 handled that format in our earlier tests.

Credits, reference-image limits and ratio counts are read from our own model registry on 8 October 2026; ratio counts exclude "auto". Speeds and the 8:1 results are our own measurements: Nano Banana 2.1 on 8 October 2026, the other three on 18 August 2026, with the sample size stated.

1. 1

   Open the workspace

   Create a free account — no API key and no Google Cloud project. The generator on this page is already set to Nano Banana 2.1.

2. 2

   Write the exact words in quotes

   Put every string you want in the image inside quotes and say where it goes. Then read the result for extra lines it added on its own.

3. 3

   Edit from your last result

   For a series of the same person, attach the previous output as the reference and restate what must stay the same — face, hair, distinguishing details.

4. 4

   Pick 1K, 2K or 4K

   1K to try ideas at 40 credits, 2K for most finished work, 4K when it will be printed or cropped hard. The exact cost shows before you run.
