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

$ai = new COM("Chilkat.Ai");

// For Azure AI Foundry we use "custom".
$ai->Provider = 'custom';

// The base URL format for the Chat Completions API when using the cognitiveservices.azure.com domain is:
// https://{resource-name}.cognitiveservices.azure.com/openai/deployments/{deployment-id}/chat/completions?api-version={api-version}

// The string "{deployment}" in the base URL is dynamically replaced with the selected AI model each time a request is sent.
// In this case, the chosen model (below) is "gpt-4o".  After substitution the base URL becomes: 
// https://chilkat.cognitiveservices.azure.com/openai/deployments/gpt-4o/chat/completions?api-version=2025-01-01-preview

// In this example, our resource name is "chilkat", and the api-version is "2025-01-01-preview"
