What's New in Nano Banana 2.1
Nano Banana 2.1 is the image generation and editing model Google released on October 6, 2026. It runs on Gemini 3.6 Flash and appears in the Gemini API as gemini-nano-banana-2.1, though you may also see it written as nanobanana 2.1. Google now lists it as the recommended upgrade from Nano Banana 2. The biggest change is planning: the model works out layout and detail before it renders. In Google's side-by-side preference tests, 2.1 scored 1050 Elo, ahead of Nano Banana 2 at 990 and Nano Banana Pro at 935.
Plans before it draws
The model reasons through layout, object counts, and spatial cues before it renders a single pixel. It runs at a medium thinking level by default, so prompts that mix several subjects, props, and style notes land on the first try more often.
Edits that stay where you point
Name a region, such as the mug on the left or the sky behind the house, and only that area changes. Lighting, framing, skin texture, and every untouched detail stay as they were, which makes small fixes fast.
Steadier faces and products
Identity holds better across editing rounds, with tracking for up to 4 characters and 10 objects in one scene. A model, mascot, or product is far more likely to keep its look from the first draft to the fifth.
Cleaner text and wide panoramas
Headlines, labels, and captions in several languages render more reliably, and infographic layouts come out tidier. Extreme 1:4, 4:1, 1:8, and 8:1 ratios also lose the tiling seams that older versions showed at 2K and 4K.
Nano Banana 2.1 Use Cases for Products, People, and Posters
Whether you searched for nanobanana 2.1 or Gemini Nano Banana 2.1, you get the same model, and it shines when details must survive several rounds of edits. Below are the jobs where it saves the most time, each with a tip to get a strong first result.
Nano Banana 2.1 Features and Specs at a Glance
Check these numbers before you choose a model for a project. They also work as a quick Nano Banana 2.1 vs Pro snapshot: in Google's tests, 2.1 matches or beats Pro on most everyday jobs while costing less per image.
1K, 2K, and 4K output
The model can render at three sizes, from quick drafts to detailed 4K images. Photoreal AI currently generates at 1K, which keeps results fast and is plenty for social posts, product listings, and web pages.
Up to 14 reference images
A single request can carry up to 14 references, with identity tracking for 4 characters and 10 objects. This page accepts up to 4 per run, which covers most product, portrait, and style-transfer edits.
Ratios from square to 8:1
Use classic shapes like 1:1, 4:5, and 16:9, or go extreme with 1:4, 4:1, 1:8, and 8:1 for banners and scroll strips. In Image to Image, Match input image keeps your upload's original shape.
Google Search grounding
Switch on search grounding to bring real landmarks, weather, or recent events into a picture with fewer factual slips. Leave it off for purely creative work, where invented details are the point.
Model ID: gemini-nano-banana-2.1
Developers call the same model as gemini-nano-banana-2.1 in the Gemini API and Google AI Studio, while casual searches often shorten it to nanobanana 2.1. On Photoreal AI you use it in the browser with no API key, SDK, or code to maintain.
Nano Banana 2.1 vs Pro on cost and speed
Pro stays a solid choice for pipelines already tuned to it. Otherwise, the Nano Banana 2.1 vs Pro decision is easy: 2.1 runs at Flash speed and costs less per image, which makes it the better default for drafts, batches, and everyday edits.
