A hands-on overview of 10 AI agent architectures
The post is a beginner-friendly tutorial on building with an FPGA board, but the image and linked article are a broader AI-engineering thread about agent design patterns.
It walks through ten common architectures:
- ReAct
- Planner-Executor
- Reflection
- Multi-Agent
- Supervisor
- Human-in-the-Loop
- Memory-Based
- Tool-Calling
- Agentic RAG
- Hybrid
The core message is that modern agent systems are usually composed from multiple patterns rather than relying on a single prompt. The post frames these as practical building blocks engineers should understand when designing production AI systems.
