The new model will replace Nano Banana Pro as the standard in many applications, yet Pro mode remains available for specialized tasks through regenerative options on premium plans like Google AI Pro and Ultra. The launch of Nano Banana 2 follows the success of its predecessor, which was released in August 2025 and quickly gained popularity, particularly in India. The new model builds on the advancements made by Nano Banana Pro, offering enhanced features such as consistent character representation (up to five characters) and object fidelity (up to 14 objects), making it ideal for storytelling and complex image requests. It also supports a wide range of resolutions from 512px to 4K and various aspect ratios, while delivering vibrant lighting, rich textures, and sharper details compared to its predecessors. In addition to its technical improvements, Nano Banana 2 will be integrated into Google’s broader ecosystem, including the Gemini API, AI Studio, and Vertex API. This makes it accessible to developers and businesses for integration into their own tools and workflows. The model also introduces SynthID watermarks, a feature designed to verify AI-generated images, ensuring transparency and authenticity. This watermark system has already been used over 20 million times since its introduction in November, highlighting the importance of traceability and verification in AI-generated content.
