Nano Banana 2 - Free AI Image Generator

Genkee's proprietary AI image model powered by Google Gemini multimodal technology

Nano Banana 2 is Genkee AI's proprietary image generation model, built on Google's Gemini multimodal architecture. Unlike third-party models that Genkee aggregates (Flux, Imagen, Seedream), Nano Banana is developed in-house — giving Genkee direct control over model optimization, pricing, and feature development. Nano Banana 2 offers the widest aspect ratio selection on the platform (10 options including 4:5 and 5:4 for Instagram), three quality tiers (1K, 2K, 4K), and support for up to 14 reference images for guided generation. Its Gemini foundation provides exceptional prompt understanding — the model handles complex multi-subject prompts with spatial relationships ("a cat sitting on a red chair next to a window with rain outside") more accurately than models that rely purely on diffusion-based architectures. Batch generation up to 4 images is supported.
