    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    var ai = new chilkat.Ai();

    // in a request for text generation.

    // Use your provider's API key.
    ai.ApiKey = "MY_API_KEY";

    // Choose a model.
    ai.Model = "gpt-5-mini";

    // See the following example showing how to upload a file
    // Upload an Image File to an AI Provider

    // Use the file_id of the pre-uploaded file.
    var file_id = "file-5CnBeuFasqNcAfti3cx4Fe";
    ai.InputAddImageFileId(file_id,"application/json");

    ai.InputAddText("What is in this image?");

    // Ask the AI for text output.
    success = ai.Ask("text");
    if (success == false) {
        console.log(ai.LastErrorText);
        return;

    // Get the text response.
    var sbResponse = new chilkat.StringBuilder();
    ai.GetOutputTextSb(sbResponse);
