7 ways Nano Banana 2 just got better and faster - how to try Google's latest image model
The new default model offers 4K resolution, consistent characters, and better text rendering across all Google apps.
Google has officially launched Nano Banana 2, rebranded as Gemini 3.1 Flash, as its new default AI image generation model across all consumer and developer platforms. The successor to last year's popular model is now available on the Gemini website, app, Google Search, Google Flow, AI Studio, and the Gemini API. Google claims it resolves key weaknesses of previous AI image generators by offering faster processing, higher fidelity, and significantly better adherence to complex user prompts. The update represents a major push to make AI-generated visuals more reliable for professional and business use cases.
Technically, Nano Banana 2 introduces seven key enhancements, including advanced world knowledge from Gemini's search data, improved consistency for up to five characters and 14 objects across image iterations, and vastly superior text rendering for creating legible greeting cards or ad mockups. It supports resolutions from 512px up to 4K and allows aspect ratio control for production-ready assets. By merging the quality of its previous 'Pro' tier with the speed of its 'Flash' tier, Google aims to eliminate the traditional speed-quality trade-off. This rollout solidifies Google's integrated AI strategy, making a powerful, unified image model the default experience for millions of users and developers.
