Gemini 2.5 Flash Image (nicknamed "nano-banana") is a high-performance image generation and editing model from Google designed for fast prompt-to-image workflows and iterative, conversational editing. It supports both generation and in-context editing and automatically embeds an invisible SynthID digital watermark into images to identify them as AI-generated. The model is surfaced on Google AI Studio and can be accessed by developers and enterprises via Vertex AI, offering production-oriented integrations and low-latency generation. Users report the model focuses on fluid conversational editing, though community support threads note occasional behavior where an edit request can return the same image repeatedly.
