Google has introduced Nano Banana 2, an image‑generation model powered by Gemini 3.1 Flash Image. The new system matches the world knowledge and reasoning of Nano Banana Pro while delivering "lightning‑fast" performance. It brings Pro‑level features—real‑time web‑search integration, infographic creation, and text overlay for marketing and greeting‑card designs—to a broader audience. Nano Banana 2 can preserve the likeness of up to five characters in a single workflow, follow precise instructions, and produce images at up to 4K resolution with richer textures and sharper details. The model will replace Pro in the Gemini app and become the default for AI Mode in Search, Lens, and Flow AI creative studio, though AI Pro and Ultra subscribers will retain access to the original Pro model for specialized tasks.
Launch and Technical Foundations
Google announced the release of Nano Banana 2, its latest image‑generation model built on the Gemini 3.1 Flash Image architecture. The company emphasizes that the new model retains the extensive world knowledge and reasoning capabilities that characterized its predecessor, Nano Banana Pro, but operates at a "lightning‑fast" speed. This performance boost is designed to enable rapid editing and quick creation of multiple iterations from a single prompt.
Expanded Capabilities
Nano Banana 2 opens up Pro‑level functionalities to a wider user base. It can pull real‑time information and images from web searches, allowing users to generate infographics, diagrams, and marketing visuals without needing separate data‑gathering steps. The model also supports adding text to images, making it useful for creating marketing materials and greeting cards.
In terms of creative control, the model can maintain the visual resemblance of up to five characters within a single workflow, a feature that benefits storyboard creation and visual storytelling. It follows precise instructions for complex requests and delivers output at resolutions up to 4K, offering richer textures and sharper details compared to earlier versions.
Impact on Existing Services
Nano Banana 2 will replace Nano Banana Pro as the default model within the Gemini app, streamlining the user experience for most customers. However, Google AI Pro and Ultra subscribers will continue to have access to the original Pro model for specialized tasks that may still require its unique strengths. The new model also becomes the default for AI Mode in Google Search, Google Lens, and the Flow AI creative studio, extending its reach across multiple Google platforms.
Availability and User Access
By making Pro‑grade capabilities more accessible, Google aims to democratize high‑quality AI‑generated imagery. The company notes that Nano Banana Pro previously generated images so realistic that they were difficult to distinguish from human‑created content, leading to limited availability due to high demand. Nano Banana 2 seeks to balance that demand with faster processing while preserving image fidelity.
Overall, Google positions Nano Banana 2 as a versatile tool for creators, marketers, and developers who need swift, high‑resolution image generation without sacrificing the depth of knowledge and precision that defined the Pro version.
