[Solved] Which of the following is the correct way to create an agent in Langchain that uses a tool? — Ans: agent = initialize_agent(llm=llm, tools=tools, agent_type='zero-shot') | LangChain

LangChain - Agents

Which of the following is the correct way to create an agent in Langchain that uses a tool?

Aagent = Agent(llm=llm, tools=tools)

Bagent = initialize_agent(llm=llm, tools=tools, agent_type='zero-shot')

Cagent = create_agent(llm, tools)

Dagent = Agent.new(llm, tools)

Step-by-Step Solution

Solution:

Step 1: Recall Langchain agent creation syntax
The standard way to create an agent with tools is using the function initialize_agent with parameters llm, tools, and agent_type.
Step 2: Evaluate options
agent = initialize_agent(llm=llm, tools=tools, agent_type='zero-shot') matches the correct syntax. Using Agent class directly, Agent.new, or create_agent are invalid in Langchain.
Final Answer:
agent = initialize_agent(llm=llm, tools=tools, agent_type='zero-shot') -> Option B
Quick Check:
Agent creation uses initialize_agent() [OK]

Quick Trick: Use initialize_agent() with llm, tools, and agent_type [OK]
