THE ORIGINAL BOOK TAUGHT YOU THE PATTERNS.
THIS BOOK UPGRADES THEM FOR 2026.
Agentic Design Patterns by Antonio Gulli is a foundational guide to building intelligent systems. But the landscape has shifted.
Models are more powerful. Frameworks have matured. Security threats are real. Costs matter.
This companion fills the five critical gaps left by the September 2025 edition and provides practical guidance for building production-ready agentic systems in 2026 and beyond.
THE MODEL LANDSCAPE PROBLEM
Understand today's frontier models, their real-world capabilities, and how they change when (and how) you use every pattern.
THE FRAMEWORK BIAS PROBLEM
Compare major frameworks including OpenAI Agents SDK, Google ADK, Microsoft Semantic Kernel, Amazon Bedrock Agents, and LangChain with practical implementation guidance.
THE ISOLATION PROBLEM
Move from isolated design patterns to production-ready architectures that combine multiple patterns effectively.
THE SAFETY BLINDSPOT
Address prompt injection, tool abuse, data leakage, multi-agent security risks, and emerging threats using practical security patterns.
THE COST & LATENCY BLINDSPOT
Design intelligent systems using cost-aware architectures, latency budgets, model routing, caching, and evaluation strategies.
BUILT FOR PRACTITIONERS. BY A PRACTITIONER.
Practical code. Real-world architectures. Production lessons. Everything you need to build, deploy, and operate intelligent agentic systems.
"The original book is a must-read. This companion is what you'll actually need when you go to production."
