Databricks Generative AI Engineer Associate Question 199
Select 3You are tasked with creating a simple chain using LangChain to process user input and pass it through a language model to generate a response. Which steps are necessary to implement this chain correctly?
- A
Define a PromptTemplate to structure the user input.
- B
Create a chain combining the PromptTemplate and a language model.
- C
Import a pre-trained chain directly from LangChain's built-in library without customization.
- D
Initialize a language model to be used in the chain.
- E
Use a memory component to store the input/output history for the chain.
Show answer and explanation
Correct answers: A, B, D
Explanation
To create a simple chain using LangChain, you need to define a PromptTemplate to structure the input, initialize a language model, and combine these into a chain. Pre-trained chains and memory components are optional and not required for this specific task.
- A. Correct.
Correct: A PromptTemplate is essential to define how user input is structured before being passed to the language model.
- B. Correct.
Correct: Combining the PromptTemplate and language model into a chain is a necessary step for implementing a functional chain in LangChain.
- C. Incorrect.
Incorrect: While LangChain provides pre-trained chains, this scenario specifies creating a custom chain, which requires manual setup.
- D. Correct.
Correct: Initializing a language model is a fundamental step in building any chain using LangChain.
- E. Incorrect.
Incorrect: A memory component is optional and not required for a basic chain implementation, as the primary goal is just to process input and generate a response.
