- Prepare your inputs
- Use a written prompt plus reference images in JPEG, PNG, or WebP. The current uploader accepts up to 10 reference images and up to 20 MB per file. Give each source a clear role and use files that you own or have permission to use. A prompt should still describe the intended subject, composition, lighting, materials, and result because the references are context, not a substitute for direction. If an image includes a person, logo, or artwork, keep the rights review separate from the creative instructions and do not assume an upload control grants permission.
- Limits to check first
- Nano Banana 2 exposes 1K, 2K, and 4K choices with the supported ratio set shown in the generator. References can influence composition, identity, and style, but they do not guarantee exact typography, facial identity, package geometry, or a perfect combination of every source. The model cannot replace a color-managed product shoot, a final typesetting pass, or legal approval. More references can also increase input cost or introduce contradictions, so start with a focused set and add complexity only when the first result is understandable.
- Credit behavior
- The live generator quotes Nano Banana 2 at the selected resolution and operation. The current price list shows 3 credits at 1K, 5 at 2K, and 8 at 4K for the standard image path, but the control panel remains authoritative if a workflow changes. The registration image offer is reserved for one GPT Image 2.5 image at 1K. Read the quote after adding references and before submitting, then follow the task record if a request fails.
- Public examples
- The public example stage beside the generator contains model-filtered inspiration and no outside-site links. It is not private history and it is not a promise that the same collection of references will produce the same image. Look for how a reference set establishes subject, background, or texture, then rebuild that relationship with your own licensed inputs and a clear prompt.
