Common Patterns

Default Model Selection

// For most applications
String DEFAULT_MODEL = "anthropic.claude-sonnet-4-5-20250929-v1:0";

// For real-time applications
String FAST_MODEL = "anthropic.claude-haiku-4-5-20251001-v1:0";

// For budget-sensitive applications
String CHEAP_MODEL = "amazon.titan-text-lite-v1";

// For complex reasoning
String POWERFUL_MODEL = "anthropic.claude-3-7-sonnet-20250219-v1:0";

Model Fallback Chain

private static final String[] MODEL_CHAIN = {
    "anthropic.claude-sonnet-4-5-20250929-v1:0",  // Primary
    "anthropic.claude-haiku-4-5-20251001-v1:0",  // Fast fallback
    "amazon.titan-text-lite-v1"                 // Cheap fallback
};
