The Text Comes Out Wrong
You ask for a poster with a headline and get lovely lettering that spells it wrong. Then every label needs a cleanup pass in a design tool, and that cleanup is where the afternoon goes.

The Image Problems Nano Banana 2.1 Fixes
Four things go wrong with AI images long before quality does. Nano Banana 2.1 is aimed squarely at them:
Your Character Changes Face
Shoot two frames of the same person and the second one comes back as somebody else. Storyboards, campaigns and course modules fall apart around frame three.
One Edit Breaks Three Things
You wanted the background swapped. The model also repainted the sofa, the light and the floor. A one-line fix turns into a full regeneration.
Every Channel Wants A Different Ratio
One idea has to become a vertical post, a square feed image and a wide site header. Re-rolling for each ratio usually means writing the prompt all over again.
Features & advantages
Advanced AI Image Generation With Nano Banana 2.1
Three capabilities separate Nano Banana 2.1 from a generic text-to-image model: type that comes out right, subjects that survive being moved, and edits that respect the rest of the frame. Together they turn image generation into something you can ship.
01
Text Rendering And Infographic Layout
Nano Banana 2.1 treats in-image text and layout as part of the brief.
Headlines, labels, price lists and step diagrams come back legible and aligned, and the facts inside an infographic land where the layout says they should.
Put exact wording in quotes, name each element, and set a high thinking level when a page carries several callouts.
This is what makes Nano Banana 2.1 usable for posters, menus, explainers and slide art instead of mood boards alone.
Generate design-ready layouts with Nano Banana 2.1 at 1K, 2K or 4K.
02
Multi-Image Fusion With Consistent Subjects
Give Nano Banana 2.1 up to 14 reference images and it blends them into one coherent scene.
Character consistency holds for up to 4 characters and object fidelity for up to 10 objects, so a cast or a product line stays recognisable across shots.
The model can also ground output in Google web and image search when a prompt depends on real-world facts.
Use it for storyboards, campaign sets and catalog pages where the same subject has to appear again and again.
Keep a series on-model with fewer regeneration rounds.
03
Mask-Based And Conversational Editing
Nano Banana 2.1 edits from plain language and keeps refining across turns.
Circle a region or scribble a rough sketch and the change lands there, while the rest of the frame stays untouched.
Swap a background, restyle one object or correct a label without rebuilding the image from scratch.
Three thinking levels — minimal, medium and high — let you trade speed for planning on harder compositions.
Fix one thing at a time instead of regenerating the whole image.
Create Professional AI Images With Nano Banana 2.1
Nano Banana 2.1 is built for the jobs that used to need a designer and an afternoon: a labelled diagram, a poster with clean type, a product placed in a new scene, a batch of edits that change one thing and nothing else. Every card below is a real use of Nano Banana 2.1 image generation, from text-to-image drafts to reference-driven edits.
Sharper Detail At 1K, 2K And 4K
Nano Banana 2.1 improves visual quality and realism across 1K, 2K and 4K output, with 1K as the default.
Material texture, edges and small details hold up when you scale to 4K for print, and wide frames no longer break into repeating tiles.
Generate a fast 1K draft, then re-run the winning prompt at 2K or 4K.
Text That Reads Correctly
Nano Banana 2.1 treats in-image text as part of the brief rather than an afterthought.
Headlines, labels, menus and step diagrams come back spelled and aligned, which is what makes an infographic usable without a cleanup pass in a design tool.
Quote the exact wording you want and raise the thinking level for dense layouts.
Edits That Stay Where You Put Them
Nano Banana 2.1 edits what you point at and leaves the rest of the frame alone.
Circle a region or scribble a rough sketch and the change lands there, while surrounding objects, lighting and shadows stay put.
That turns a one-line instruction into a finished edit instead of another round of manual masking.
One Instruction, One Region: Targeted Edits With Nano Banana 2.1
Case study
Change the sofa, keep the room
The brief was one sentence: make the sofa deep teal. Nano Banana 2.1 masked the region, restyled the upholstery and left the walls, the rug, the plant and every shadow exactly where they were.
No regeneration, no manual selection, no cleanup. That is the difference between an edit and a do-over.
Create Nano Banana 2.1 Images In Three Simple Steps
Nano Banana 2.1 rewards a clear brief. Write what you want, set the frame, then refine in conversation — the whole path from prompt to finished image stays inside Textideo.
Step 1
Describe Your Image
Write a prompt that names the subject, the style, the lighting and the mood.
If specific words need to appear in the picture, put them in quotes so Nano Banana 2.1 renders the exact lettering.
Optionally attach reference images for composition, likeness or product fidelity.
Step 2
Pick Ratio, Resolution And Thinking Level
Choose an aspect ratio from tall 1:8 to ultra-wide 8:1 and set output to 1K, 2K or 4K.
Nano Banana 2.1 defaults to 1K and medium thinking, which suits most first passes.
Raise the thinking level to high for dense infographics and multi-reference compositing.
Step 3
Refine And Export
Ask Nano Banana 2.1 for the change you want — a different background, a recoloured object, a corrected label — and keep iterating.
When the image is right, export it at the resolution your channel needs.
Types Of Images You Can Make With Nano Banana 2.1
Nano Banana 2.1 covers the formats teams actually ship: explainer diagrams, campaign posters, catalog product shots and wide banners. Each one leans on a different strength of the model — layout, lettering, subject fidelity or panoramic framing.
Infographics & Diagrams
Turn a set of notes into a labelled diagram, a process flow or a cutaway with Nano Banana 2.1.
Labels land where you asked for them and the layout stays tidy, which matters for lessons, reports and social explainers.
Use a high thinking level when one diagram carries several callouts.
Posters & Campaign Art
Build event posters, sale banners and ad layouts where the headline has to read at a glance.
Nano Banana 2.1 keeps the type on the baseline and the margins consistent, so a whole campaign set can be produced in one session.
Set the ratio once and re-run the layout for every channel.
Product Shots In New Scenes
Place one product into many settings while its shape, colour and detailing stay true to the original.
With up to 14 reference images, Nano Banana 2.1 keeps up to 10 objects faithful, which is how a catalog stays consistent across an entire shoot.
Replace a studio day with a prompt and a product photo.
Wide Banners & Panoramas
Generate ultra-wide headers at ratios such as 4:1 and 8:1, and tall 1:8 strips for vertical placements.
Nano Banana 2.1 fixes the tiling artifacts that wide frames used to show at 2K and 4K, so a banner comes out as one continuous image.
Render at 4K when the banner will be printed or cropped into several sizes.
Who Nano Banana 2.1 Is For
Nano Banana 2.1 suits anyone whose image work keeps returning to the same three problems: type that has to be right, subjects that have to stay the same, and edits that must not spill. Here is where it lands hardest.
Designers & Illustrators
Produce layout-first drafts — posters, diagrams, icon sets — with lettering you can hand to a client.
Iterate on composition and palette through conversation instead of rebuilding artboards.
Keep one character or mascot consistent across an entire series.
Marketing & Ecommerce Teams
Drop one product into many scenes without a reshoot, and keep packaging, label and colour intact.
Generate campaign art for every channel from a single brief.
Swap backgrounds and seasonal styling with targeted edits.
Educators & Content Teams
Turn a lesson outline into a labelled diagram or cutaway that students can actually read.
Refresh visuals for new terms and languages while the layout stays where it was.
Produce explainer art at the ratio each platform wants.
Product Teams & Developers
Prototype UI concepts, mockups and empty-state art before design picks them up.
Batch variations through prompts and pick the strongest direction.
Run Nano Banana 2.1 in a browser workspace instead of managing API keys and SDKs.
What Creators Say About Nano Banana 2.1
Three kinds of work, one shared complaint: the tools were fine at pictures and bad at details. Here is what changed when the details started holding.
“Labeling a diagram used to mean rebuilding it in three tools just to get the type straight. Now I put the headline in quotes, set a high thinking level, and the layout comes back ready to drop into the deck — spelled the way I asked for.”
Marta Kessler
Art Director, independent design studio
“Catalog shoots used to eat a full day per drop. I pass one product photo in as a reference and place it across four scenes, and the label and colour stay identical. We only book the studio for hero shots now.”
Daniel Roth
Ecommerce Lead, home goods brand
“Consistency was the reason I nearly gave up on AI images — the same character came back with a different face every single time. With references loaded the cast holds across a whole module, so I can ship a series instead of a lucky one-off.”
Elena Whitmore
Instructional Designer

Frequently Asked Questions About Nano Banana 2.1
Straight answers about Nano Banana 2.1: what changed since Nano Banana 2, how it compares with Nano Banana Pro, which resolutions and reference images it takes, and how to get cleaner lettering and steadier characters out of every prompt.
What is Nano Banana 2.1?
Nano Banana 2.1 (gemini-nano-banana-2.1) is Google's high-efficiency image generation and conversational editing model, released in October 2026 as an update to Nano Banana 2.
It accepts text, images, video and PDF as input and returns images and text, and it is built for work where layout, lettering and subject consistency matter.
On Textideo you can run Nano Banana 2.1 in the browser instead of wiring up an API key and a cloud project.
What is new in Nano Banana 2.1 compared with Nano Banana 2?
Nano Banana 2.1 improves visual quality and realism at 1K, 2K and 4K output, with 1K as the default, and fixes the tiling artifacts that wide and panoramic ratios such as 4:1 and 8:1 could show at 2K and 4K.
Text rendering and infographic layout accuracy are noticeably better, and multi-image fusion now takes up to 14 reference images.
Google also added configurable thinking levels, with medium as the default, plus grounding through Google web and image search.
Nano Banana 2.1 vs Nano Banana Pro: which one should I use?
Nano Banana 2.1 is the more efficient counterpart to Gemini 3 Pro Image, also called Nano Banana Pro. It keeps Flash-level speed and cost while handling most generation and editing work.
Nano Banana Pro suits the heaviest visual jobs, where the highest world knowledge, advanced localisation and precise brand control matter more than speed.
For infographics, posters, product shots and character series, Nano Banana 2.1 is usually the faster and cheaper place to start.
Can Nano Banana 2.1 render readable text inside images?
Yes. Cleaner text rendering is one of the headline improvements in Nano Banana 2.1, alongside infographic layout accuracy.
Put the exact words you want in quotes, name every element you expect to see, and raise the thinking level to high for dense layouts that carry several labels.
For a straightforward edit, the default medium level is usually enough.
How many reference images can Nano Banana 2.1 use at once?
Nano Banana 2.1 supports multi-image fusion with up to 14 reference images in a single request.
Within that set it holds character consistency for up to 4 characters and object fidelity for up to 10 objects, which is what keeps a product catalog or a storyboard coherent.
Load the references you care about most first when you are close to the limit.
What resolutions and aspect ratios does Nano Banana 2.1 support?
Nano Banana 2.1 outputs at 1K, 2K or 4K, with 1K set as the default.
It covers a wide spread of aspect ratios, from tall 1:8 strips to ultra-wide 8:1 panoramas, and the tiling artifacts that used to appear on those wide frames at 2K and 4K have been fixed.
Treat 2K as an everyday default and 4K as the print setting.
Does Nano Banana 2.1 edit existing images, or only generate new ones?
Both. Nano Banana 2.1 is a conversational editing model, so you describe a change in plain language and keep refining it across several turns.
Mask-based and sketch-based editing let you circle or scribble over the region you want changed while the rest of the frame stays put.
That is what makes targeted fixes — a background, a colour, a label — practical without reopening a full design file.
What are thinking levels in Nano Banana 2.1?
Thinking levels decide how much planning Nano Banana 2.1 does before it draws: minimal, medium or high, with medium as the default.
Use minimal when speed matters most, and high for dense infographics, tricky compositions or multi-reference compositing.
Medium handles the majority of straightforward generations and edits well.
Do I need an API key or Google AI Studio to use Nano Banana 2.1?
Not if you use Nano Banana 2.1 through Textideo.
Google exposes the model in the Gemini app, AI Mode in Search, Google AI Studio, Flow, Stitch, Google Ads and the Gemini API, and most of those routes ask for a Google account or an API key.
Textideo runs the same model inside a browser workspace, so there is nothing to install and no key to rotate.
Is Nano Banana 2.1 free to use?
That depends on the route you take. Google ships Nano Banana 2.1 across its own products and API, and third-party platforms such as Textideo run it under their own credit and plan rules.
Because quotas differ by provider, check what your current plan covers before you queue a large batch.
A single low-resolution test is still the cheapest way to learn how Nano Banana 2.1 responds to your prompts.
