Multimodal Input: File Data

Demonstrates sending a request that includes both text and PDF file data for the AI to analyze.

Note: At the time of writing this example, xAI, Perplexity, and DeepSeek do not have the ability to accept non-image multimodal data or URLs.

Perl

use chilkat();

$success = 0;

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

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

#  The provider can be "openai", "google", or "claude".
#  At the time of writing this example, "deepseek", "xai", and "perplexity" do not have the ability to process non-image multimodal inputs.
#  Support for additional providers will be added in future versions of Chilkat.
$ai->put_Provider("claude");

#  Use your provider's API key.
$ai->put_ApiKey("MY_API_KEY");

#  Choose a model.
$ai->put_Model("claude-opus-5");

#  Add both text input, and PDF file data.
$ai->InputAddText("What is in this file?");

$bd = chilkat::CkBinData->new();
#  We're passing a relative local file path here.. (relative the the app's current working directory)
$success = $bd->LoadFile("qa_data/pdf/shakespeare.pdf");
if ($success == 0) {
    print $bd->lastErrorText() . "\r\n";
    exit;
}

#  Provide the filename in the 1st argument.  The file extension is important to indicate the type of file.
$ai->InputAddFileData("shakespeare.pdf",$bd,"");

#  Ask the AI for text output.
$success = $ai->Ask("text");
if ($success == 0) {
    print $ai->lastErrorText() . "\r\n";
    exit;
}

#  Get the text response.

#  Sample output:

#  This PDF file contains a famous quote from William Shakespeare's "Romeo and Juliet". The quote appears twice on the page:
#  
#  "These violent delights have violent ends
#  And in their triumph die, like fire and powder,
#  Which as they kiss consume. The sweetest honey
#  Is loathsome in his own deliciousness
#  And in the taste confounds the appetite.
#  Therefore love moderately; long love doth so;
#  Too swift arrives as tardy as too slow."
#  
#  The file also includes a portrait image of William Shakespeare. This particular quote is spoken by Friar Lawrence in the play, warning about the dangers of passionate, 
#  immoderate love - suggesting that love that burns too intensely tends to burn out quickly, just as fire and gunpowder consume each other when they meet.
