Google DeepMind has introduced Nano Banana 2, also referred to as Gemini 3.1 Flash Image, expanding its AI image generation capabilities across the Google ecosystem. The update brings faster generation speeds while retaining features previously associated with higher-fidelity Pro models.
The release positions Nano Banana 2 as a bridge between speed and quality, two attributes that have often been traded off in generative image tools. According to Google, the model combines advanced world knowledge, improved instruction-following, subject consistency, and production-ready image specifications at what it describes as “Flash speed.”
The model is rolling out across the Gemini app, Google Search, AI Studio, Vertex AI, Flow, and Google Ads.
