Google has revealed today the new iteration of its well-known image creation model, Nano Banana 2. This updated model, technically termed Gemini 3.1 Flash Image, is capable of generating images that appear more lifelike than its earlier version. Furthermore, it will now serve as the default model in the Gemini app for Fast, Thinking, and Pro modes.

The initial release of Nano Banana occurred in August 2025, leading users to create countless images using the Gemini app, particularly in countries such as India. In November, the company launched Nano Banana Pro, which enabled users to generate more intricate and high-resolution images.

Nano Banana 2 keeps some of the high-detail features of the Pro model but enhances the speed of image production. The company states that users can generate images with resolutions ranging from 512px up to 4K, accommodating various aspect ratios.

With Nano Banana 2, users can ensure continuity for up to five characters and maintain the fidelity of 14 objects within a single workflow, enhancing the narrative experience. According to Google, users can also make elaborate requests with specific details for image generation. Additionally, the model allows for the creation of images with brighter lighting, enriched textures, and clearer details.

With this launch, Nano Banana 2 is set to be the standard model for image creation across all applications within the Gemini app. The company is also integrating it as the standard option for image generation in its video editing platform, Flow.

In Search, Nano Banana 2 will serve as the default for Google Search outcomes via Google Lens and in AI Mode across 141 nations via the Google app and on the web for both desktop and mobile.

For subscribers using Google’s premium plans, Google AI Pro and Ultra, the option to continue utilizing Nano Banana Pro for specialized tasks remains available by regenerating images through the three-dot menu.

For developers, Nano Banana 2 will be accessible in a preview format through the Gemini API, Gemini CLI, and the Vertex API. It will also be offered via AI Studio and the company’s development tool Antigravity, which was introduced last November.

The company announced that all images generated with the new model will feature a SynthID watermark, which signifies that they are AI-created. Furthermore, these images will be compatible with C2PA Content Credentials, a framework established by a consortium of companies including Adobe, Microsoft, Google, OpenAI, and Meta. Since the introduction of the SynthID verification in the Gemini app last November, usage has surpassed 20 million instances, according to Google.
