Beta

This model is currently in public testing. Not everyone has access, and API requests may also be unstable.

Overview

Generate ultra-sharp, cinematic frames from short text prompts using Google’s Gemini Nano Banana Pro model. Compared with the base Nano Banana release, the Pro tier unlocks:

• Wider aspect ratios (from square up to 21:9 panoramic)
• Higher fidelity presets (resolution up to 4K)
• Better prompt adherence thanks to an upgraded vision-language alignment stack
