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. Perl

use chilkat();

$success = 0;

$success = 0;

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

$ai = chilkat::CkAi->new();

#  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-5.6-luna");

#  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.
$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 == 0) {
    print $ai->lastErrorText() . "\r\n";
    exit;
}

#  Get the text response.
$sbResponse = chilkat::CkStringBuilder->new();
$ai->GetOutputTextSb($sbResponse);
print $sbResponse->getAsString() . "\r\n";
