Google’s post introduces Nano Banana 2, also called Gemini 3.1 Flash Image, as a new image model that tries to combine the higher-end capabilities of Nano Banana Pro with much faster generation and editing speed. It says the model is better at using real-world knowledge, following detailed instructions, generating readable text inside images, and keeping characters or objects consistent across multiple images, while also supporting production-ready sizes up to 4K. Google positions it as a more practical tool for fast creative work such as infographics, storyboards, marketing assets, and localized visuals, rather than just one-off image creation. The company also says Nano Banana 2 is rolling out across products including the Gemini app, Search, AI Studio, Vertex AI, Flow, and Google Ads, while expanding its AI content labeling approach with SynthID and C2PA verification.
