Show HN: I built a UI for Gemini 3 (Nano Banana) Batch API – 50% cheaper (github.com)

A developer has unveiled a user interface for the Gemini 3 Batch API, dubbed "Nano Banana", which enables more efficient and cost-effective image generation capabilities. The platform allows users to create images from text prompts, transform existing images, and process multiple requests asynchronously, all while utilizing local storage through SQLite and offering options for output resolution and creative control. Notably, the Gemini Batch API provides a 50% reduction in costs compared to real-time API calls, making it an appealing choice for developers. This development is significant for the AI/ML community as it enhances accessibility to advanced image generation tools while reducing operational costs. The implementation supports flexible features such as temperature control for creativity versus consistency and provides users with the option to bring their own Gemini API key, enhancing user privacy and control. Built with modern frameworks like Next.js and React, the platform showcases a full-stack approach that emphasizes user experience, allowing easy integration for batch processing of tasks, which can lead to broader experimentation and innovation within the generative AI space.
