<ul data-eligibleForWebStory="true">The ReAct design pattern in AI combines reasoning and acting to solve complex tasks effectively and produce accurate results.First introduced in 2022, the ReAct pattern is gaining popularity as a key architecture for modern agentic AI agents.ReAct involves a cycle of reasoning, acting, observing, and repeating until the task is completed satisfactorily.It enables agents to think, plan, and execute step by step, distinguishing it from traditional AI workflows.Implementation of ReAct includes an Orchestrator Agent, Reasoning Agent, Acting Agent, and Observing Agent working in a loop.ReAct-powered AI workflows excel at complex, multi-step problems, leveraging real-time feedback for strategy refinement.Pros include accuracy, adaptability, transparency, and integration with external tools, while cons involve complexity and potential latency.Tools like data packs, MCP servers, SERP APIs, and agent browsers are essential for implementing ReAct efficiently.ReAct design pattern boosts AI agents in thinking, acting, and learning dynamically to efficiently solve tasks and adapt to feedback.Overall, ReAct is transforming AI workflows by merging reasoning and acting, leading to more robust and effective AI agents.
