Google Flow Users Spot Nano Banana 2.1 Label, but Google Has Not Confirmed a New Image Model

A reported Nano Banana 2.1 label has surfaced inside Google Flow for some users, raising questions about whether Google is staging a new image model or simply testing a product-surface name. Google has not published an announcement, model card, API identifier or public specification for Nano Banana 2.1, so the label should not yet be treated as a confirmed release.
