Google has launched Nano Banana 2, an updated AI image generation model that combines the precision of its Pro version with faster processing speeds. Powered by Gemini 3.1 Flash Image, the tool becomes the new default across Google's platforms, including the Gemini app and search features. It aims to deliver more accurate and realistic images while expanding creative capabilities.
Google announced Nano Banana 2 on February 26, 2026, marking a significant update to its popular AI image generator. The new model, technically known as Gemini 3.1 Flash Image, builds on previous versions by integrating the advanced capabilities of Nano Banana Pro—such as improved text rendering and web searching—with the speed of the standard Flash variant. This allows for quicker image generation and editing, enabling users to create multiple iterations from a single prompt.
Key improvements include enhanced world knowledge drawn from the internet via the Gemini 3.1 large language model, which helps produce more faithful representations of objects and accurate infographics. Nano Banana 2 offers Pro-like text accuracy in images, making it suitable for tasks like designing greeting cards or marketing materials. It maintains character consistency for up to five characters in a workflow and can accurately render as many as 14 objects, supporting visual storytelling with richer textures, vibrant lighting, and sharper details.
The model supports a wider range of aspect ratios and resolutions, from 512px square up to 4K widescreen. Google states that Nano Banana 2 will replace both the standard and Pro variants as the default image generator in the Gemini app, search, AI Studio, Vertex AI, and Flow. However, subscribers to Google AI Pro and Ultra plans retain access to Nano Banana Pro for specialized tasks. Images generated with the new model include invisible watermarks called content credentials, which can help identify AI-created content when uploaded to Gemini—though this detection works only for Google-generated images.
Originally debuted last fall, Nano Banana quickly gained popularity for its photorealistic outputs, surpassing competitors like Midjourney and OpenAI in photo editing. This release continues Google's rapid advancements in AI, aiming to balance speed and quality for broader accessibility.
