As Large Language Models (LLMs) evolve into autonomous agents, understanding agentic workflow design patterns has become essential for building robust agentic AI systems. These patterns represent proven architectural approaches that determine how AI agents coordinate, make decisions, and solve complex problems. These design patterns can be used in several use cases including enterprise automation, software development, research analysis, content creation, customer service, and process orchestration. The following nine design patterns represent foundational architectures that can be used for building agentic workflow systems. Learn from this visual animation – Agentic Workflow Design Patterns.
Uses LLMs as direct policy models to generate actions or plans without search or feedback loops. Examples include ReAct for question answering and Plan-and-Solve for math problems. Simple, straightforward execution but limited exploration of alternatives. Best for well-defined tasks with clear action sequences.

Explores multiple reasoning paths using tree/graph structures before selecting optimal solutions. Examples include Tree-of-Thoughts and RAP workflows. Uses evaluators to assess different paths and search algorithms like Monte Carlo Tree Search. Excellent for complex problem-solving requiring exploration of solution space.

Iteratively improves responses through feedback from self-reflection, tools, environment, or humans. Examples include Reflection and Self-Refine. Incorporates learning loops where agents analyze their performance and refine future attempts. Ideal for tasks requiring continuous improvement and error correction capabilities.

Multiple specialized agents work together with defined roles and coordination mechanisms (voting, debate, role-based). Includes hierarchical structures and peer-to-peer networks. Examples include MetaGPT and AgentScope. Enables complex task decomposition, parallel processing, and leveraging diverse agent capabilities for comprehensive problem-solving.

Specialized multi-agent systems for information retrieval and synthesis. Multiple retrieval agents work in parallel, each optimized for specific data sources, while a central LLM synthesizes information. Improves accuracy, reduces hallucinations, and handles diverse knowledge bases effectively for complex queries.
