ReAct and Plan-and-Execute Agents
Understand and implement advanced agent architectures that combine reasoning and action for complex task completion.
Beyond Simple AI Agents
Welcome to Advanced Agent Architectures! So far, you've learned about basic agents and chains in LangChain. These are great for straightforward tasks.
However, real-world problems can be complex. They often require agents to reason, make decisions, and perform multiple steps to achieve a goal. This is where advanced architectures come in.
Introducing ReAct Agents
One powerful advanced architecture is ReAct, which stands for Reasoning and Acting. It's inspired by how humans solve problems.
- Reasoning: The agent thinks about the problem, current state, and what to do next.
- Acting: The agent then performs an action, often by using a tool.
This cycle allows agents to dynamically adapt and solve complex tasks.
