 By now, you've likely heard of tools like ChatGPT or Generative AI. The concept is simple: you provide a prompt, and a model—often called a Large Language Model (LLM)—generates a paragraph or even an entire page of text. This output can be used for various purposes, including creative writing, answering questions, and coding.
 
-Moreover, Generative AI has evolved into multi modal capabilities, allowing you to provide an image or video as input and receive a variety of outputs. This advancement has significantly enhanced many people's workflows—not only by generating text but also by summarizing, translating, and more.

 - **API request**: you need to send a request to the generative AI model API with the input text. This is done using the fetch function in JavaScript (Node.js). Included in this request should also be your API key. It's recommended as you consider security to not hardcode the API key in your app but rather use environment variables. Additionally, consider looking into managed identity if you're using a provider like Azure as it's considered a more secure way to access resources. With managed identity you can assign more granular permissions to your app and the best part is that the cloud provider takes care of the authentication for you.
