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

my $ai = Chilkat2::Ai->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->Provider('claude');

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

# Choose a model.
$ai->Model('claude-opus-5');

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

# 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.
