Building reliable AI applications relies heavily on robust architectural design, not just the underlying model. This guide outlines 10 core design patterns commonly used by top AI companies:
- ReAct (Reason + Act): Models alternate between reasoning and taking action to improve logic.
- Planner-Executor: Separates task breakdown from execution for better reliability and debugging.
- RAG (Retrieval-Augmented Generation): Retrieves external knowledge to reduce hallucinations, standard for enterprise knowledge bases.
- Reflection: The model reviews and improves its own output before responding, acting as built-in QA.
- Multi-Agent Collaboration: Multiple specialized agents divide tasks to handle complex workflows.
- Tool Calling: Dynamically utilizing external tools like web search, APIs, and code interpreters.
- Memory: Incorporating short-term, long-term, and vector memory for personalized, context-aware experiences.
- Human-in-the-Loop: Integrating human review for critical decisions to balance automation with accountability.
- Event-Driven: Automatically triggering AI workflows based on system events, ideal for business automation.
