//  See Global Unlock Sample for sample code.

//  The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
//  Support for additional providers will be added in future versions of Chilkat.

//  Use your provider's API key.

//  Choose a model.

//  Add a text input.

//  Ask the AI for text output.

//  -------------------------------------------------------------
//  The response is in markdown format.
//  Also see Markdown to HTML Conversion Examples.

//  Sample output:

//  # Hello! 👋
//  ## Welcome!
//  It's **great** to meet you. How can I *assist* you today?
//  ---
//  Feel free to ask me anything, and I'll respond in `markdown` format.

//  -------------------------------------------------------------------------------------------
//  Send the 2nd request in the conversation.

//  Sample output:

//  ## Wisdom from Confucius
