Is nano-banana:official an independent Google model?
It is the specific ID used to call Nano Banana; the corresponding public model name is Gemini 2.5 Flash Image. Nano Banana is the model's nickname; :official does not constitute a new Google model name, nor is it equivalent to Nano Banana Pro. Use the full ID when integrating.
Can I generate images using only a prompt?
Yes. Select generate and provide a prompt describing the subject, environment, lighting, composition, and style to start text-to-image generation. If you want to match an existing product or brand visual, you can also add image references; choose the aspect ratio based on the actual use case, such as a cover, banner, or vertical content.
How do I replace backgrounds or combine multiple images?
Use edit, provide the images to process through image_urls, and describe the relationship between the assets in the prompt. For example, retain the product's shape and replace the environment with a morning-lit wooden table scene. When combining multiple images, clearly specify the purpose of the subject image and background image rather than writing only vague compositing requirements.
Can it automatically continue the previous round of editing?
When creating consecutive variants, it is recommended to use the image selected in the previous round again as a reference and clearly state what needs to be retained and modified in this round. This clarifies the editing baseline without relying on implicit history; for character or product series, stable identity-feature descriptions should also be retained to reduce unnecessary changes.
How can generated results be integrated into business workflows?
The endpoint returns an image URL along with task_id and trace_id, making it easy to associate tasks with results. For batch asset workflows, use async and callback_url to handle completion notifications, then send images through screening, review, and archiving steps; before formal release, the subject details and text still need to be checked.
