Delphi ActiveX

Multimodal Input: File URL

See more AI Examples

Demonstrates sending a request that includes both text and a PDF file URL 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.

// Sample output:

// The file contains a quote from William Shakespeare's "Romeo and Juliet" and an image of Shakespeare. The quote is from Act 2, Scene 6:
// 
// “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.”
