// 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.

// Sample output:

// The image depicts a small, bright orange starfish (also known as a sea star) with five symmetrical arms radiating from a central disc. 
// It has a textured, bumpy surface that gives it a realistic, almost spiky appearance, and there's a small hole or indentation at the center, 
// which might represent the mouth or a natural feature. The starfish is shown against a plain white background, and it appears to be a simple, 
// illustrative or clipart-style graphic rather than a photograph.
