LangChain - Agents

Which of the following is the correct way to create a ReAct agent in LangChain?

Aagent = ReActAgent(llm=llm, tools=tools)

Bagent = ReActAgent(tools=llm, llm=tools)

Cagent = ReActAgent()

Dagent = ReActAgent(llm)

Step-by-Step Solution

Solution:

Step 1: Recall ReAct agent constructor parameters
The ReAct agent requires a language model (llm) and a list of tools (tools) as named arguments.
Step 2: Check each option for correct syntax
agent = ReActAgent(llm=llm, tools=tools) correctly passes llm and tools by name. agent = ReActAgent(tools=llm, llm=tools) swaps them incorrectly. agent = ReActAgent() misses required arguments. agent = ReActAgent(llm) passes only llm without tools.
Final Answer:
agent = ReActAgent(llm=llm, tools=tools) -> Option A
Quick Check:
Correct parameters = llm and tools [OK]

Quick Trick: Pass llm and tools as named parameters to ReActAgent [OK]
