Nano Banana 2 brings Pro quality at Flash speeds, rolling out to Gemini app 

Google today announced Nano Banana 2 as its latest image model rolling out now to the Gemini app.

Officially, Nano Banana 2 is Gemini 3.1 Flash Image. It follows Gemini 2.5 Flash Image (Nano Banana) from August and Gemini 3 Pro Image (Nano Banana Pro) in November.

Compared to Nano Banana, you’ll notice richer textures and sharper details with vibrant lighting. Precise instruction following means the model “adheres more strictly to your complex requests” to capture the “specific nuances of your idea so the image you get is the image you asked for.” There’s also:

• Subject consistency: Maintain character resemblance of up to five characters and the fidelity of up to 14 objects in a single workflow, allowing you to storyboard and build narratives without altering the appearance of your inputs.
• Production-ready specs: Make attention grabbing assets with full control of various aspect ratios and resolutions from 512px to 4K, ensuring your visuals stay sharp whether they are for a vertical social post or a wide-screen backdrop.

Pro features now available in a Flash model include accurate text rendering and translation, as well as advanced world knowledge “to more accurately render specific subjects.” This allows you to generate data visualizations, infographics, turn notes into diagrams, and create marketing mockups. 

In the Gemini app, Nano Banana 2 replaces Nano Banana Pro across all models (Fast, Thinking, and Pro). However, Google AI Pro and Ultra subscribers “will keep access to Nano Banana Pro for specialized tasks by regenerating images via the three-dot menu.” There’s also a new templates feature to pick an image style.

Nano Banana 2 is also coming to AI Mode and Google Lens. It’s also the default image generation model in Flow. Finally, the model is available in preview for AI Studio, Gemini API, Google Antigravity, Vertex AI, and Gemini CLI. Nano Banana 2 can be used for “rapid generation,” while Nano Banana Pro is for “high-fidelity tasks requiring maximum factual accuracy.”

On the safety front, Google is coupling SynthID watermarks with C2PA Content Credentials to “provide users with a more holistic and contextual view of not just if AI was used, but how.”  C2PA verification is coming to the Gemini app.
