Google Nano Banana
Google's original Nano Banana, the Gemini 2.5 image model for fast generation and conversational editing that holds a subject's likeness across successive edits.
Nano Banana is a cloud image-generation model built by Google. It generates images from a text prompt, and can take reference images to guide style or composition (image-to-image). It supports 10 aspect ratios. Images can be saved as JPEG and PNG. It runs through OpenRouter, Replicate, and Google using your own API key, from about $0.0387 per image.

Samples
Generated with Nano Banana via Runware. The same three prompts run against every model in the catalog, first result kept, so the only thing that changes between two models’ tiles is the model.
Materials, reflections, macro detail
Skin texture, lighting, shallow depth of field
Text rendering, layout, flat colour
Google and Google DeepMind build the Gemini family of multimodal models, the Imagen and Nano Banana image models, the Lyria music models, and the Veo video models.
