Basic Chatbot Implementation

class BasicChatbot:
    def __init__(self):
        self.responses = {
            "greeting": "Hello! How can I help you today?",
            "farewell": "Goodbye! Have a great day!",
            "default": "I'm not sure about that. Could you rephrase?"
        }
        
    def get_response(self, input_text):
        if "hello" in input_text.lower():
            return self.responses["greeting"]
        elif "bye" in input_text.lower():
            return self.responses["farewell"]
        return self.responses["default"]

Advanced AI Agent Implementation

class AIAgent:
    def __init__(self, llm_provider, tools):
        self.llm = llm_provider
        self.tools = tools
        self.memory = []
        
    async def process_request(self, user_input):
        # Analyze and plan
        plan = await self.create_plan(user_input)
        
        # Execute actions
        results = []
        for action in plan:
            tool_result = await self.execute_tool(action)
            results.append(tool_result)
            
        # Generate response
        return await self.synthesize_response(results)

Hybrid Solution Implementation

class HybridAssistant:
    def __init__(self):
        self.chatbot = BasicChatbot()
        self.ai_agent = AIAgent()
        
    async def handle_request(self, user_input):
        complexity = self.analyze_complexity(user_input)
        
        if complexity < 0.5:
            return self.chatbot.get_response(user_input)
        else:
            return await self.ai_agent.process_request(user_input)

6. Decision Making Guide

When to Choose Each Solution

Choose a Chatbot When:

• Budget is limited
• Use cases are well-defined
• Quick responses are crucial
• Maintenance simplicity is important
• Predictability is key

Choose an AI Agent When:

• Complex problem-solving is needed
• Integration with multiple systems is required
• Adaptability is important
• Learning from interactions is valuable
• Budget allows for higher costs

Cost-Effective Implementation Strategy

1. Start with a simple chatbot for basic use cases
2. Gradually add LLM capabilities for complex queries
3. Implement AI agent features for specific complex tasks
4. Use hybrid approach to optimize cost vs capability
5. Monitor usage and adjust based on metrics
