Databricks Generative AI Engineer Associate Question 201
Select 4You are tasked with creating a simple chain using LangChain that concatenates a user's input with a predefined string. Which of the following steps are required to code this chain successfully?
- A
Import necessary modules from LangChain, such as SimpleChain and PromptTemplate.
- B
Define a PromptTemplate that specifies the format of your input and output.
- C
Create a SimpleChain by combining the PromptTemplate with a Language Model (e.g., OpenAI model).
- D
Explicitly define a custom tokenizer for the input processing.
- E
Initialize the chain and call it with the input data to execute it.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To create a simple chain in LangChain, you need to import the relevant classes, define a PromptTemplate for input/output structure, combine it with a Language Model using SimpleChain, and execute the chain with input data. Custom tokenization is not required for basic chain creation.
- A. Correct.
Correct: Importing necessary modules like SimpleChain and PromptTemplate is required to build a chain in LangChain.
- B. Correct.
Correct: PromptTemplate is essential to define the structure of the input and output in the chain.
- C. Correct.
Correct: A SimpleChain combines a PromptTemplate with a Language Model to process and generate responses.
- D. Incorrect.
Incorrect: Defining a custom tokenizer is not mandatory for creating a simple chain in LangChain. Default tokenization suffices for most use cases.
- E. Correct.
Correct: Initializing the chain and calling it with input data is necessary to execute the functionality of the chain.
