Nano Banana 2 AI Image Generator
Google names Nano Banana 2 as Gemini 3.1 Flash Image. Readkidz sends the current stable `gemini-3.1-flash-image` identifier on this image route. Write a visual brief, optionally attach up to four authorized reference images, choose 1K, 2K, or 4K and one of fourteen aspect ratios, then review the live credit estimate. Readkidz is independent and is not Google or Gemini.
How it works
- 1Enter with Nano Banana 2 selected
Use the composer above to carry both your brief and `model=nano_banana` through sign-in into Readkidz Quick Create. This keeps the exact model route attached instead of dropping you into broad engine discovery.
- 2Run a controlled first image
Describe the subject, composition, medium, lighting, and any text that must appear. If you attach references, say what each one controls and what may change. Start at 1K when you are still testing the prompt or layout.
- 3Inspect before the higher-resolution pass
Confirm the selected ratio, resolution, and live charge, then review the result for identity drift, spelling, facts, anatomy, and unwanted copied details. Move to 2K or 4K only after the composition is worth refining.

Frequently asked questions
What is Nano Banana 2?
Nano Banana 2 is Google's name for Gemini 3.1 Flash Image, a model for image generation and conversational editing. Google documents the stable API id as `gemini-3.1-flash-image`. Readkidz uses Nano Banana 2 as its product label for a separate Quick Create route.
Does Readkidz use Google's current stable Nano Banana 2 identifier?
Yes. Readkidz currently sends `gemini-3.1-flash-image`, the stable Nano Banana 2 identifier in Google's public documentation. Readkidz remains an independent product and does not reproduce every Gemini interface or API control.
Can Nano Banana 2 create a new image and edit a reference?
The Readkidz route accepts a text brief with optional image references, so you can start from words alone or describe changes around uploaded visual material. It does not reproduce Google's full conversational interface or every upstream editing control.
How many reference images can I attach?
Quick Create currently accepts up to four reference images for Nano Banana 2. Use each reference for a specific job such as identity, composition, palette, or medium, and upload only material you have permission to use.
Which resolutions and aspect ratios are available in Readkidz?
The configured resolution choices are 1K, 2K, and 4K. The fourteen ratios are 1:1, 16:9, 9:16, 4:3, 3:4, 1:4, 1:8, 2:3, 3:2, 4:1, 4:5, 5:4, 8:1, and 21:9. The current local defaults are 2K and 1:1.
What are the Nano Banana 2 credit rates?
The enabled Readkidz variants currently charge 100 credits for 1K, 150 credits for 2K, and 250 credits for 4K per task. These values resolve from the same model configuration used for billing; confirm the live estimate before submission.
Is the Readkidz Nano Banana 2 generator free?
New accounts currently receive 1000 starter credits that remain valid for 30 days without requiring a card. Nano Banana 2 is an image model, so the server's subscription-only video gate does not apply, but every generation still consumes the displayed task credits.
What happens to my credits if Nano Banana 2 generation fails?
When submission or a terminal generation task fails, Readkidz starts a refund for that charge. If the refund cannot complete immediately, the backend records it for pending recovery instead of showing an unconfirmed refund as finished.
How should I write a first Nano Banana 2 prompt?
Write one production brief with subject, setting, composition, medium, lighting, exact text, and constraints. For an edit, name what must change and what must remain. A focused 1K pass is usually a more useful diagnostic than combining several unrelated scenes and styles at once.
Is this an official Google or Gemini image generator?
No. Readkidz is an independent creative platform and is not Google or Gemini. Model names identify the configured route only. Review every output for accuracy and rights; generated content does not grant permission to use a person's likeness, a trademark, copyrighted characters, or an uploaded image.
