Why use Gemini 2.5 Flash Image for image?
Ultra-fast image generation for high-volume creative pipelines
Gemini 2.5 Flash Image (also known as Nano Banana) produces visuals at extremely high speed, making it perfect for rapid UA creative refreshes, LiveOps asset generation, and fast ideation cycles. Its low-latency performance helps teams iterate without slowing down production.
Consistent structure and clear readability across asset types
The model generates well-defined characters, environments, and in-game items that retain strong shape clarity across variations. This makes assets highly readable at mobile-game sizes and reliable for production needs.
Optimized for large-scale variation testing and creative exploration
Nano Banana excels at generating dozens or hundreds of stylistic variations from minimal prompt changes. This makes it ideal for performance-driven UA testing, seasonal theme exploration, and rapid concept iteration.

Rapid character and cosmetic concepting
Quickly generate new characters, outfit variations, colorways, and cosmetic ideas for season drops or LiveOps events. Flash Image’s speed lets teams explore wide visual territories before locking direction.

High-throughput UA creative generation
Produce large sets of UA-ready images with clear focal points and clean compositions. Nano Banana helps performance teams test many creative ideas quickly, accelerating the feedback loop for CTR and CPI improvements.

Fast environment and in-game item pack production
Generate backgrounds, event-themed elements, and item sets for shop rotations or content updates at scale. Flash Image maintains consistency across batches, making it ideal for LiveOps pipelines that need frequent asset refreshes.
FAQ
How much does Gemini 2.5 Flash Image cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
