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

    let ai = CkoAi()!

    // 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-4-1-20250805"

    // Add both text input, and PDF file data.
    ai.inputAddText("What is in this file?")

    // Provide the filename in the 1st argument.  The file extension is important to indicate the type of 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.
