Question: 14
You are building a chatbot application using Langchain in Databricks that takes a user's query and provides a response from a language model. You want to deploy a simple conversational chain to respond to user queries. Choose the correct implementation for this chain. Which of the following code snippets correctly implements a conversational chain for chatbot interaction using Langchain?

A
from langchain.chains import SimpleChain
from langchain.llms import OpenAI
llm = OpenAI()
chatbot_chain = SimpleChain(llm)
response = chatbot_chain.run("What is the capital of France?")
print(response)
from langchain.chains import SimpleChain
from langchain.llms import OpenAI
llm = OpenAI()
chatbot_chain = SimpleChain(llm)
response = chatbot_chain.run("What is the capital of France?")
print(response)
B
Explanation:
The correct answer is A because it shows the proper implementation of a conversational chain using Langchain. Here's the detailed explanation:
Why Option A is correct:
- It imports the necessary components from Langchain (
SimpleChainandOpenAI) - It initializes the language model (
llm = OpenAI()) - It creates a chain instance (
chatbot_chain = SimpleChain(llm)) - It properly runs the chain with a user query and prints the response
Key Langchain concepts demonstrated:
- Chains: Langchain chains are sequences of calls to components like models, prompts, etc.
- SimpleChain: This is a basic chain type that takes user input and passes it directly to the LLM
- LLM Integration: The code properly integrates with OpenAI's language model
What makes this implementation correct for a chatbot:
- It handles user queries directly
- It provides responses from the language model
- It follows Langchain's standard pattern for chain creation and execution
Note: While this is a simplified example, in real-world applications you might use more sophisticated chains like ConversationChain that maintain conversation history, but SimpleChain is valid for basic query-response scenarios.
