Identify the two models before comparing
Google identifies Nano Banana 2 as gemini-3.1-flash-image and Nano Banana 2.1 as gemini-nano-banana-2.1. They are distinct models. Google describes 2.1 as an update with improvements in text rendering, visual quality and multi-turn consistency. These are vendor statements, not a benchmark performed by this website.
Record the exact endpoint used by your provider. A display name alone cannot establish which model produced an image. Our connected generation stays on fal; the controls and availability shown in this workspace determine what you can run here.
Start with one brief and a visible pass rule
Use a job you already understand: a catalog image of a blue bottle, a poster headed “OPEN HOUSE”, or an edit that changes a background while preserving a character. Give both models the same text and the same reference files. Match shape and output size where both endpoints allow it.
Before generating, write what counts as a pass: the headline matches exactly, the bottle retains its silhouette, and nothing blocks the label. Avoid changing the prompt after seeing the first model’s output. Otherwise you are comparing two briefs as well as two models.
Inspect the changes that matter to your work
Compare spelling at full size and at the final display size. Check faces, accessories and product edges against the reference. For a wide banner, look at repeated textures and seams across the full canvas. When revising an image, list the details that should remain unchanged and inspect them again after the edit.
Use a simple record for each output: model, task, spelling pass, preservation pass, layout pass, corrections needed and final usable file. Save unsuccessful examples too. One attractive image cannot tell you how reliable a model will be across your workload.
Compare usable results and the complete cost
Record the quote before submission, the actual charge, the time to a usable download and any additional edits. Distinguish waiting in this site from waiting at the provider. If a request times out, check its task status before submitting another one; a duplicate request can incur another charge.
A higher first-request price may still fit your budget if it reduces corrections. A lower quote may fit simple tasks that already pass review. This page does not claim a measured speed winner or publish a fixed price ratio between the models.
Switch in a small, reversible batch
Keep your accepted prompts and source files, then test a small set of representative tasks with the new model. Include at least one text layout and one reference edit. Compare the actual files before replacing the model in an automated workflow.
This workspace has Nano Banana 2.1 generation and edit endpoints configured. Check the generator for current availability and the request quote. Connection alone does not establish a controlled comparison result. Preserve the actual endpoint in task records; do not label another model's output as 2.1.
Questions before you start
Is Nano Banana 2.1 always better than Nano Banana 2?
Google documents improvements, but this website has not published a controlled benchmark. Choose based on outputs that pass your specific brief and budget.
Can I reuse my Nano Banana 2 prompts?
Use them as the first test input. Check endpoint parameters and inspect the result before adopting them in production; a saved prompt does not guarantee an identical image.
Does this page establish a shutdown date?
No. Check the provider’s current model lifecycle notice for the exact endpoint you use. This comparison does not infer a closure date from a model update.
