Model family overview
What is the Nano Banana AI image generator?
Nano Banana is Google’s name for Gemini native image-generation capabilities. ZMS AI currently lists Nano Banana 2, identified by Google as Gemini 3.1 Flash Image, and uses this family page to decide whether that focused workspace fits the assignment.
Google documents text-to-image and text-and-image editing plus SynthID watermarking, while ZMS exposes only its registered route and visible controls. Choose Nano Banana 2 here for a prompt or reference-led test; return to the AI image generator hub when the assignment needs cross-family model choice. Live delivery still requires verification.
Creative fit
Where Nano Banana fits in image production
Nano Banana 2 is the only current family route, so this section focuses on assignments that benefit from its prompt-and-reference workflow rather than inventing a multi-version comparison.
Reference-led revisions
Attach approved images for identity, object geometry, palette, material, or layout. State the requested change and protected facts separately, then review every return rather than assuming references stayed exact.
Controlled variation sets
Hold the core prompt and references stable while testing crop, background, palette, or light one at a time. This creates a reviewable variation set instead of a collection of unrelated attractive images.
Human-reviewed consistency
Use explicit protected details to reduce drift across a small set, then inspect identity, hands, text, logo placement, product geometry, and composition. Reference support is a workflow input, not a consistency guarantee.
Version guide
Choose Nano Banana 2 or return to the image hub
Nano Banana has one current ZMS version, so the useful decision is whether to open that focused route or step back to the cross-family image model directory.
| Version | Best for | Workspace inputs | Planning note |
|---|---|---|---|
| Nano Banana 2 | Prompt-led generation and reference-based editing in one focused model route | Text prompt plus the references supported by the version workspace | Open the version page for its reference roles, controls, and current status |
| Image model hub | Assignments that still need a family or model decision | A deliverable brief before a model-specific input path is chosen | Return to /image to compare GPT Image, Nano Banana, and other image routes |

Decide whether Nano Banana 2 fits
Because the family currently has one route, these checks decide whether to continue into Nano Banana 2 or go back to cross-family selection.
- 01
Name the deliverable
Record the placement, format, audience, subject, and message. Decide whether the assignment is open generation, a controlled edit, or a reference-led variation before selecting a model route.
- 02
Audit source images
Check that references clearly show the identity, object, layout, palette, or material they control. Remove sources that conflict or add no distinct information to the task.
- 03
Choose focused or cross-family
Continue to Nano Banana 2 when its prompt-and-reference path fits. Return to the image hub when model comparison, different controls, or another family's evidence is still needed.
- 04
Open the version route
Use the version page for exact reference roles, settings, task submission, and review notes. Verify returned media and debit before expanding one test into a production variation set.
Prompt framework
Adapt a Nano Banana brief for references
The family has one current route, so the important adaptation is not version syntax but how references divide authority. Keep each source's role explicit and move exact limits to the version page. Use the planning artwork to connect those choices to one reviewable frame; it prepares input and review decisions rather than claiming model output quality or live delivery.
- 01
Set one image job
Name the deliverable, audience, subject, and central message before describing style. A product hero, portrait, diagram, or social graphic should each have one testable purpose.
- 02
Assign reference authority
Give each reference one job: identity, geometry, palette, material, layout, or environment. If two sources disagree, state priority or remove one instead of asking the model to compromise.
- 03
Separate change and preserve
Write the requested change first, then list protected identity, geometry, text zones, pose, crop, or color facts. This makes drift visible and keeps revisions focused.
- 04
Move limits to the route
Use Nano Banana 2 for current reference counts, formats, controls, and service status. Keep settings out of the creative brief unless they affect composition or review.
Nano Banana 2 starter stills
Four Nano Banana 2 stills from this workspace
Copy a complete Nano Banana 2 prompt and paste it into the workspace above. These stills were generated on this page's own text-to-image path, so the prompt you copy is the prompt the model already ran.
Market fishmonger stall
A fishmonger in a rubber apron arranges silver mackerel on crushed ice at a covered market stall, price cards handwritten in chalk. Overhead fluorescent light mixed with daylight from a high window, wet concrete floor, documentary photography, sharp detail on the ice and scales.
Letterpress workbench
An overhead flat lay of a letterpress workbench: composing stick, scattered lead type, an ink-stained brayer, and a freshly pulled proof reading OPEN TUESDAYS in bold slab serif. Warm tungsten light raking across the wood grain, deep shadows, tactile texture, editorial product photography.
Greenhouse botanist
A botanist in a linen shirt labels seedling trays inside a Victorian glasshouse, condensation beading on the panes behind her. Soft overcast light diffused through glass, palms and ferns receding into humid haze, muted green palette, shallow depth of field on the handwritten labels.
Night noodle counter
A narrow late-night noodle counter seen from the customer side: steam rising off a bowl, the cook's hands lifting noodles from boiling water, hand-painted menu strips on the tiled wall. Warm amber bulbs against cool night blue outside the doorway, reflective steel counter, cinematic still.
Selection notes
Choose Nano Banana with evidence
Known now: Nano Banana 2 is the sole current route and the four cards above are current generated pairs with recorded prompts. They demonstrate this workspace path but do not guarantee identity, text, logo, geometry, or reference fidelity on another assignment.
| Decision | Current fact | Review action |
|---|---|---|
| Choose the route | Nano Banana 2 is the sole current family route and prepares prompt-led generation or reference-based editing in one focused ZMS workspace. | Open Nano Banana 2 when its reference and control path fits; otherwise return to the image model hub for another family. |
| Read the evidence | The four visible stills are current Nano Banana 2 generated pairs with recorded prompts. They prove only those tasks, not repeatable identity, text, logo, or geometry fidelity. | Use each pair as a prompt-and-result reference, then test the actual subject and approved sources. Reject drift rather than generalizing from attractive examples. |
| Approve production | A connected route and visible settings do not guarantee reference preservation, signed-in completion, final debit, rights clearance, or production consistency. | Run one representative task, inspect protected details and permissions, retain the result record, then check ZMS AI pricing before scaling a variation set. |
FAQ
Nano Banana AI questions
Practical answers for choosing a version, preparing inputs, and reviewing a first generation.
Why have a family page with one Nano Banana version?
It separates two decisions: whether Nano Banana 2 fits the assignment and how to use that version's controls. If the model family is not settled, this page sends the task back to the image hub.
Are the four Nano Banana stills current pairs?
Yes. The four cards are current Nano Banana 2 generated pairs with the recorded prompts. They prove those specific text-to-image tasks, not consistent performance on a different subject or reference-led edit.
Do references guarantee an exact Nano Banana edit?
No. References guide the task but do not guarantee identity, product geometry, text, logo, pose, or layout preservation. Separate requested changes from protected details and inspect every returned image.
When should I return to the image model hub?
Return when the assignment still needs a family comparison, another model's evidence, different controls, or a more suitable input path. Stay on Nano Banana 2 when its focused prompt-and-reference route already fits.
What does Google's SynthID statement establish?
It establishes Google's upstream claim that Nano Banana model outputs include SynthID. It does not by itself prove that a specific ZMS task completed, returned an image, or preserved the watermark through later processing.
Is ZMS AI an official Google Nano Banana product?
No. ZMS AI is an independent creative workspace and is not affiliated with or endorsed by Google.
