Google lists October 29, 2026 as the shutdown date for gemini-3.1-flash-image and recommends gemini-nano-banana-2.1. This date concerns the Google API, not every reseller.

Google describes improvements to text, image quality and tiling. These are vendor claims, not a general Plykit win rate. Our small coloring-page sample favored minimal backgrounds; complex line relationships still need human review.

An actual generated example

Generated with Plykit’s official QA account on October 7, 2026: 4K, native 3584×4800, 6 credits. Prompt: a scarf-wearing triceratops stepping over a low log, with a minimal background. One extra grass tuft illustrates why outputs need review. No reference image was used; this example does not establish cross-page consistency.

How many credits do 1K, 2K and 4K cost?

Can I edit with a reference image?

This page uses the Standard reference-image editing path. Follow the limits shown in the upload controls. Edits can change text, labels, people or object details; inspect the output before use.

What changed from the previous version?

Google describes improvements to text, image quality and tiling. These are vendor claims, not a general Plykit win rate. Our small coloring-page sample favored minimal backgrounds; complex line relationships still need human review.

Is one generated image a complete KDP publishing package?

No. Images still need page-by-page review, layout, a cover and PDF preflight. The single example below is not a complete book or evidence of Amazon approval.

Is generation free, and does Plykit provide this API?

Generation requires enough Plykit credits. Google’s model API is separate from this web tool. This page does not promise free generation or provide a developer API.
