LangChain - Fundamentals

Given this LangChain code snippet, what will be the output?

from langchain.llms import OpenAI
llm = OpenAI(model_name="gpt-4")
prompt = "Say hello"
response = llm(prompt)
print(response)

AIt will print an empty string

BIt will print the prompt string 'Say hello'

CIt will raise a syntax error due to missing parentheses

DThe model will generate a greeting like 'Hello!'

Step-by-Step Solution

Solution:

Step 1: Understand llm call behavior
Calling llm(prompt) sends the prompt to the model and returns generated text.
Step 2: Analyze print output
Printing response outputs the model's generated greeting, not the prompt itself.
Final Answer:
The model will generate a greeting like 'Hello!' -> Option D
Quick Check:
llm(prompt) returns model output [OK]

Quick Trick: llm(prompt) returns generated text, not the prompt [OK]
