Membangun kelas pengelola percakapan

Anda bergabung dengan ChargeNet, sebuah perusahaan yang meluncurkan jaringan nasional stasiun pengisian daya cepat untuk kendaraan listrik. Tugas Anda adalah membangun ChargeBot, chatbot dukungan pelanggan. Langkah pertama adalah membuat kelas ConversationManager untuk melacak riwayat percakapan sehingga Claude dapat menghasilkan balasan yang koheren.

Petunjuk latihan

Buat list kosong untuk menyimpan conversation_history.
Tambahkan metode add_message() yang menerima role dan content, lalu menambahkan sebuah dictionary ke riwayat.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

class ConversationManager:
    def __init__(self):
        self.bedrock = boto3.client("bedrock-runtime", region_name="us-east-1")
        # Create an empty list for the conversation history
        ____

    # Add the method to append messages    
    def ____(self, ____, ____):
        self.conversation_history.append({"role": role, "content": content})

Learn the fundamentals of Amazon Bedrock, AWS's fully managed foundation model service. Start with basic setup and authentication, explore available foundation models like Claude and Titan, and master essential API interactions. This chapter covers setting up a development environment, choosing appropriate models for a use case, and implementing proper API request handling, including streaming responses and error management.

Exercise 1: Accessing Amazon Bedrock Exercise 2: Initializing the Bedrock client Exercise 3: Retrieving Bedrock model details Exercise 4: Selecting a foundation model Exercise 5: Using the correct model in Bedrock Exercise 6: Generating text in Bedrock

In this chapter, you'll progress through three key lessons. Starting with the basics of text generation and response handling, you'll then advance to sophisticated prompt engineering techniques like few-shot learning and structured outputs. The final lesson covers model parameter optimization, teaching learners to fine-tune settings like temperature and token limits for optimal results. Each lesson builds upon the previous, moving from fundamental API interactions to advanced parameter control for specific use cases.

Exercise 1: Generating text with language models Exercise 2: Enhancing prompts with role assignment Exercise 3: Processing model responses and error handling Exercise 4: Foundation model report categorization Exercise 5: Applying prompt engineering techniques Exercise 6: Implement few-shot learning for geometry Exercise 7: Creating structured output prompts Exercise 8: Working with different model parameters Exercise 9: Adjusting creativity with temperature control Exercise 10: Controlling output with top_p and max_tokens Exercise 11: Parameters for product descriptions

In this chapter, you’ll build robust and responsible applications with Amazon Bedrock, moving beyond basic API interactions. Starting with conversational AI, you’ll master state management and context handling to create coherent chat experiences. You’ll then explore advanced prompting techniques, learning how to generate diverse content types while maintaining consistent style and tone. The chapter covers critical production aspects like error handling, rate limiting, and efficient response processing. Finally, you will implement ethical guardrails and safety measures, ensuring your AI applications are both powerful and responsible.
