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

$ai = new Ai();

// The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
// Support for additional providers will be added in future versions of Chilkat.
// xAI (Grok) will be used here..
$ai->Provider = 'xai';

// Use your provider's API key.
$ai->ApiKey = 'MY_API_KEY';

// Choose a model.
$ai->Model = 'grok-4.5';

// Add both text input, and image data
$ai->InputAddText('Describe what you see in the following image.');

$bd = new BinData();
// We're passing a relative local file path here.. (relative the the app's current working directory)

    // Ask the AI for text output.

// Get the text response.

// 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.
