⚡ Production Architecture

Consolidated into a single optimized service for enterprise performance:

$platform = \Drupal::service('llm.platform');

// High-performance AI operations via contrib AI module
$result = $platform->ai('chat', [
  'messages' => $messages,
  'model' => 'llama2-7b-chat',
  'temperature' => 0.7,
  'max_tokens' => 256
]);

// Enterprise workflows via contrib ECA module  
$platform->workflow('process_document', $context);

// External service integration with load balancing
$data = $platform->external('bfapi', 'getModels', ['timeout' => 30]);

// Scalable model management via Entity API
$models = $platform->models('list', ['status' => 'active']);

// Production agent orchestration via Queue API
$platform->agents('deploy', $config);
