How to Use Fine Tuned Models With Gemini API Calls

I want to use my gemini fine tuned modal on my nextJs app

Welcome to the forum. A good place to start is 使用 Gemini API 进行微调  |  Google for Developers.

Hope that helps.

Thanks for the links. However I would like to use the tuned Gemini model in my NodeJS application I haven’t found a resource that explains well how to authenticate using NodeJS.
