In August of last year, our Gemini Image model, Nano Banana, became a viral sensation, redefining image generation and editing. Then in November, we released Nano Banana Pro, offering users advanced intelligence and studio-quality creative control. Today, we’re bringing the best of both worlds to users across Google.
Introducing Nano Banana 2 (Gemini 3.1 Flash Image), our latest state-of-the-art image model. Now you can get the advanced world knowledge, quality and reasoning you love in Nano Banana Pro, at lightning-fast speed.
Intelligence and visual quality at Flash speed
Nano Banana 2 brings the high-speed intelligence of Gemini Flash to visual generation, making rapid edits and iteration possible. It makes once-exclusive Pro features accessible to a wider audience, including:
- Advanced world knowledge: The model pulls from Gemini’s real-world knowledge base, and is powered by real-time information and images from web search to more accurately render specific subjects. This deep understanding also helps you create infographics, turn notes into diagrams and generate data visualizations.
- Precision text rendering and translation: Nano Banana 2 allows you to generate accurate, legible text for marketing mockups or greeting cards. You can even translate and localize text within an image to share your ideas globally.

Enhanced creative control
Nano Banana 2 also dramatically closes the gap between speed and visual fidelity, delivering high-quality, photorealistic imagery. Here’s what our newest model offers and has improved on from the original Nano Banana:
- 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.
- Precise instruction following: With enhanced instruction following, the model adheres more strictly to your complex requests, capturing the specific nuances of your idea so the image you get is the image you asked for.
- 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.
- Visual fidelity upgrade: Nano Banana 2 delivers vibrant lighting, richer textures and sharper details, maintaining high-quality aesthetics at the speed expected from Flash.

Robust provenance: marking and verification
As generative media evolves, so must the tools we use to identify and understand it. We continue to deepen our provenance approach, by coupling our state-of-the-art SynthID technology with interoperable C2PA Content Credentials, we provide users with a more holistic and contextual view of not just if AI was used, but how.
Our provenance tools are already making an impact. Since its launch in November, our SynthID verification feature in Gemini app has been used over 20 million times across various languages, helping people identify Google AI-generated images, video and audio. We’ll soon be bringing C2PA verification to the Gemini app, too.
