Tips before you run
Start with the default settings and change one input at a time. Keep the result you like on your board so the next step can use it.
If you add a reference file, use a link the workflow can read. Check the inputs and credit estimate on the board before starting a run.
Working with this model
Reference images
Wire Reference Images once and hand it several images: it is a list port, so several wires into that one socket all survive, and so does a single upstream that emits several images.
Image 1 and the numbered Image 2..Image 10 slots go first, in slot order, and then everything on Reference Images, in wire order. The same URL wired into both a slot and the list keeps its slot position and counts once.
Whatever ends up first in the request is the image the model EDITS, and that is Image 1 only when Image 1 is wired. Leave Image 1 empty and wire Image 2 instead, and Image 2 becomes the image being edited. The numbered slots are read in slot order and an empty one is simply skipped. Wire the subject to Image 1.
The first 10 images reach the model. Anything past 10 is dropped, silently as far as the request goes, and the numbered slots win: if 10 slots are wired, nothing on Reference Images is sent. There is no run warning for the drop yet.
You do not need to stitch reference photos into one contact sheet any more, and you should not: stitching divides every face by the number of photos in the sheet before the model ever sees it.
Skip node passes Image 1 through while Image 1 is the ONLY numbered slot wired. It serves whatever is on Image 1, never a reference, and Reference Images can be wired alongside without changing that.
Wire a second numbered slot (Image 2 and up) and the card can no longer be skipped transparently: two numbered slots are two candidate sources and nothing on the card says which one to pass on, so Skip passes NOTHING and the run record says so per node. Leaving Image 1 empty passes nothing for the same reason. This is not new to Reference Images; a card with two numbered slots behaved this way before that socket existed.
Common questions
How do I use Nano Banana Lite on Wireflow?
Set the inputs above and choose Open in a workflow. Sign in to save your board, then check its credit estimate before you run.
Can I use Nano Banana Lite through an API?
Yes. Save a workflow with this model, then call the Wireflow run API with its workflow ID. The API tab has examples you can copy.
What changes the credit price?
The price shown uses the model defaults. Your inputs and model settings can change the total. The workflow shows an estimate before you run.
Can I connect this to another model?
Yes. Open it in a workflow and connect its output to another node with a matching input type.
