Nano Banana 2.1

Nano Banana 2.1 is an advanced image generation and conversational editing model developed by Google, built on the Gemini 3 series infrastructure. Released as an update to Nano Banana 2, the model maintains high computational efficiency while delivering major enhancements in visual quality, prompt adherence, multi-turn character consistency, and text rendering. It supports output resolutions up to 4K and handles wide and panoramic aspect ratios without common tiling artifacts.

Key Capabilities

The model introduces robust multi-image fusion supporting up to 14 reference images, enabling character consistency for up to four unique characters and object fidelity across multiple elements. Nano Banana 2.1 also excels at precise image editing through natural language instructions, allowing users to modify specific parts of an image while preserving the overall scene context. Furthermore, its enhanced text rendering and infographic layout accuracy make it well-suited for generating posters, diagrams, menus, and data-heavy visual content.
