[Solved] Which of the following is the correct way to create a simple chain in LangChain? — Ans: chain = LLMChain(llm=llm, prompt=prompt) | LangChain

LangChain - Chains and LCEL

Which of the following is the correct way to create a simple chain in LangChain?

Achain = LLMChain(llm=llm, prompt=prompt)

Bchain = Chain(llm, prompt)

Cchain = create_chain(llm, prompt)

Dchain = LLMChain(prompt)

Step-by-Step Solution

Solution:

Step 1: Recall LangChain syntax for creating a simple chain
The correct syntax uses named parameters like llm= and prompt= when creating an LLMChain.
Step 2: Check each option
chain = LLMChain(llm=llm, prompt=prompt) matches the correct syntax. The other options use incorrect function or class names or miss the llm parameter.
Final Answer:
chain = LLMChain(llm=llm, prompt=prompt) -> Option A
Quick Check:
Use named parameters for LLMChain [OK]

Quick Trick: Use named parameters when creating chains [OK]
