Google Flow adds Nano Banana 2.1 image model, promoting it at zero credits

Google Flow's X account (@FlowbyGoogle) says it has added the Nano Banana 2.1 image model and that image generation costs 0 credits in Google Flow.

The post says the model produces more natural-looking images, with improvements in visual design, editing and subject consistency. These are the post's claims, and no independent testing is cited.

The free-credit condition applies to image generation in Google Flow as the post describes it. The post does not say whether the 0-credit price covers other Flow features or other Nano Banana models.
