Nano Banana Pro is Google DeepMind's AI image generation model, built directly into Google Antigravity. If you've seen it mentioned in Antigravity's release notes or in agent task outputs, this guide explains exactly what it is and how it works.
What Is Nano Banana Pro?
Nano Banana Pro (based on Gemini 3 Pro Image) is the successor to the original Nano Banana model (which ran on Gemini 2.5 Flash). It's not a shortcut button or a lightweight chat mode — it's a full AI image generation model that Antigravity's agents can invoke as part of a task.
The name is a Google DeepMind codename that stuck through public launch.
