Referencing a Pre-Uploaded Image File by file_id in an AI Request

See more AI Examples

Currently, OpenAI is the only AI provider that supports referencing a pre-uploaded image in a request for text generation. C++

#include <CkAi.h>
#include <CkStringBuilder.h>

void ChilkatSample(void)
    {
    bool success = false;

    success = false;

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

    CkAi ai;

    // OpenAI is currently the only AI provider that supports referencing a pre-uploaded image by file_id
    // in a request for text generation.
    ai.put_Provider("openai");

    // Use your provider's API key.
    ai.put_ApiKey("MY_API_KEY");

    // Choose a model.
    ai.put_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.
    const char *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) {
        std::cout << ai.lastErrorText() << "\r\n";
        return;
    }

    // Get the text response.
    CkStringBuilder sbResponse;
    ai.GetOutputTextSb(sbResponse);
    std::cout << sbResponse.getAsString() << "\r\n";
    }
