What this comparison is allowed to claim
Section 1 of this review is about one invented character across a short set. The comparison is with drawing a model sheet by hand. Write the character rules once and paste them into every prompt. Changing the rules mid-set is the usual reason a series falls apart. The fixed limit, which this article will not soften, is: Consistency is a goal, not a guarantee. If image three changes the face, stop and reuse the closest accepted image as the next reference. Keep hair, clothes, and the same face plan. Change pose and setting only. The pass/fail line for this section is whether the outfit and face still match image one.
Open https://nanobananalite.pro/create only after that line is written down. The image workspace embedded on this article is the same browser tool. Typing a prompt here does not create a file and does not spend a credit. Generation spends a credit, and a failed image still spent it. Nano Banana Lite does not offer a public API or an API key for this workflow. If drawing a model sheet by hand can meet a requirement this edit cannot, use that option instead of prompting again. For one invented character across a short set, a useful second attempt changes one instruction. Repeating the same sentence is not a review, it is a spend. Save the prompt, the date, and the reason you accepted or rejected the image. That record is the evidence. A prettier thumbnail is not.
Practical pass for one invented character across a short set: the source is a photo you are allowed to edit, the output still shows hair, clothes, and the same face plan, and the only intentional difference is pose and setting only. Reject the output when the outfit and face still match image one fails, when new objects appear, or when small text is invented. Pricing and the remaining credits are on https://nanobananalite.pro/pricing. The background-edit limit is also stated on https://nanobananalite.pro/remove-background: an AI edit, not a guaranteed transparent PNG. The prompt template on https://nanobananalite.pro/image-to-prompt covers subject, composition, lighting, color, style, and camera. Use those pages as the product contract. Do not add a benchmark this site has not published.
- Subject: one invented character across a short set.
- Keep: hair, clothes, and the same face plan.
- Change: pose and setting only.
- Stop if: the outfit and face still match image one is false.
