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

loAi = CreateObject('Chilkat.Ai')

* 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.
loAi.Provider = "claude"

* Use your provider's API key.
loAi.ApiKey = "MY_API_KEY"

* Choose a model.
loAi.Model = "claude-opus-4-1-20250805"

* Add both text input, and PDF file data.
loAi.InputAddText("What is in this file?")

loBd = CreateObject('Chilkat.BinData')
* We're passing a relative local file path here.. (relative the the app's current working directory)
lnSuccess = loBd.LoadFile("qa_data/pdf/shakespeare.pdf")
IF (lnSuccess = 0) THEN
    ? loBd.LastErrorText
    RELEASE loAi
    RELEASE loBd
    CANCEL
ENDIF

* Provide the filename in the 1st argument.  The file extension is important to indicate the type of file.
loAi.InputAddFileData("shakespeare.pdf",loBd,"")

* Ask the AI for text output.
lnSuccess = loAi.Ask("text")
IF (lnSuccess = 0) THEN
    ? loAi.LastErrorText
    RELEASE loAi
    RELEASE loBd
    CANCEL
ENDIF

* Get the text response.
loSbResponse = CreateObject('Chilkat.StringBuilder')
loAi.GetOutputTextSb(loSbResponse)
? loSbResponse.GetAsString()

* 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.
