        REAL-WORLD PROXY SERVER CONFIGURATION EXAMPLE:
        ===============================================
        
        In a proxy_server_config.yaml file, you would define:
        
        model_list:
          - model_name: bedrock-claude-3-haiku

        FUNCTION CALLING WITH PROXY SERVER:
        ===================================
        
        When using the proxy server with this configuration:
        
        1. Client calls: supports_function_calling("bedrock-claude-3-haiku")
        2. Proxy server resolves to: bedrock/converse/anthropic.claude-3-haiku-20240307-v1:0
        3. LiteLLM evaluates the underlying model's capabilities
        4. Returns: True (because Claude 3 Haiku supports function calling)
        
        Without the proxy server configuration context, LiteLLM cannot resolve
        the custom model name and returns False.
        
        
        BEDROCK CONVERSE API BENEFITS:
        ==============================
        
        The Bedrock Converse API provides:
        - Standardized function calling interface across providers
        - Better tool use capabilities compared to legacy APIs
        - Consistent request/response format

        FUNCTION CALLING WITH PROXY SERVER:
        ===================================
