Kie.ai

Kie.ai offers the Nano Banana API, an affordable and reliable solution for image generation and editing that leverages the power of Gemini 2.5 Flash Image Preview. Initially launched under the codename “Nano Banana” on the LMArena testing platform, this tool quickly gained fame for its photorealism, fast rendering speeds, and precise editing results. At just $0.02 per image, Kie.ai provides an economical alternative to more expensive APIs like Google’s Gemini, offering developers access to high-quality image generation with clear and stable documentation. The Nano Banana API allows developers to perform context-aware natural language editing, enabling complex changes like scene modifications or object swaps with simple text prompts. It also supports photorealistic, physics-aware image generation, ensuring accurate lighting, textures, and shadows. Additionally, the API offers multi-image fusion and composition, allowing users to combine elements from different sources into a unified final output. Users can try out the tool for free via the Playground, test various prompts and workflows, and fully integrate the API for production use by signing up for an API key, sending requests, and retrieving results for seamless integration.
