gemini-3.1-flash-image

Gemini 3.1 Flash Image (codenamed Nano Banana 2) is engineered for developers who need high-fidelity visual synthesis without the typical latency overhead of larger diffusion models. While previous iterations often forced a trade-off between prompt adherence and generation speed, this model bridges that gap by delivering Pro-tier aesthetic quality at Flash-class inference speeds. It is particularly optimized for real-time applications, such as dynamic UI asset generation, interactive gaming environments, and rapid prototyping workflows. For integration, the model supports complex image-to-image editing and sophisticated text-to-image pipelines via a streamlined API. Compared to standard heavyweight models, it offers a significantly lower time-to-first-token for visual data, making it a superior choice for production environments where user experience depends on near-instantaneous visual feedback.
