// This example assumes the Chilkat API to have been previously unlocked.
// 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.
ai.ApiKey = @"MY_API_KEY";

// Choose a model.

// If the conversation is the first to be created, it is also automatically selected.

// 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.

// -------------------------------------------------------------------------------------------

// ## Wisdom from Confucius
