Google has taken a new step in the field of AI-powered image generation. The Nano Banana 2 model, also known as Gemini 3.1 Flash Image, is now generally available with enhanced capabilities to produce faster and more realistic images compared to its predecessor.
High Quality, Shorter Time
Nano Banana 2 retains the high detail fidelity of Nano Banana Pro, released in November 2025, while significantly reducing generation time. Images can be created in sizes ranging from 512 pixels to 4K resolution. Within a single workflow, consistency is maintained for up to five characters and detail is preserved for up to 14 objects. This capability strengthens narrative storytelling in complex scenes.
Default Across All Google Products
The model is now integrated as the default image generation tool in the Gemini app’s Quick, Thinking, and Pro modes. It is also combined with the video editing agent Flow. Access is available via Google Search through Lens and AI Mode to desktop and mobile web users in 141 countries.
Transparency and Standards
Google has announced that all images generated by Nano Banana 2 will be watermarked with SynthID. This watermark enables users to easily detect that content was AI-generated. Additionally, the images are compatible with the C2PA Content Credentials standard, developed with contributions from companies such as Adobe, Microsoft, OpenAI, and Meta. This supports efforts to preserve the authenticity and integrity of digital content.
Google reported that the SynthID feature has been used over 20 million times since November 2025. For developers, the model is accessible for preview via tools such as the Gemini API, Vertex AI, and AI Studio.
The new model has been optimized to meet high demands for visual content generation in large-user markets such as India. Users can now fulfill complex visual requests with more vibrant lighting, rich textures, and sharper edges.
