Kie AI serves Gemini chat models through the same API key as Nano Banana and Veo. Here is what the Gemini chat API supports today, based on the Kie AI API documentation.
Call Gemini models through the native Gemini format (streamGenerateContent) or an OpenAI-compatible chat/completions endpoint, using the model ID from the table above, such as gemini-3-8-flash; check the Kie AI API docs for the supported request fields.
Send text together with images, video, audio or PDF files in the same request.
Define your own functions for the model to call, or turn on Google Search grounding for up-to-date answers.
Set the thinking level to low or high, and request JSON-schema output when your app needs parseable responses. Gemini chat models currently support chat requests only and have not yet been adapted for agent use.
Access multiple Google Gemini API models through one platform. Use Gemini image API, Gemini AI API, and Gemini video API models together without managing separate providers or workflows.
Process text, images, and video through a unified Gemini API workflow. Build applications that understand and generate different types of content within one AI system.
Choose the right Gemini model API for each use case. Use lightweight models for speed, advanced models for reasoning, and specialized models for image and video generation.
Build products that need responsive performance and reliable scaling. Gemini AI API models support fast interactions and stable workloads across chat, image, and video applications.
