Mastering Agentic AI with OpenAI

Building an AI Agent Is Easy. Building One You Can Trust in Production Is Engineering. Agentic AI systems are moving fast from research papers and demos into production software. Mastering Agentic AI with OpenAI is a practical, authoritative guide for engineers, architects, and technology leaders designing and operating production-ready Agentic systems on the OpenAI platform — covering everything from multi-turn interactions to autonomous AI operation at enterprise scale. The book progresses from agent foundations and tool integration through multi-agent orchestration, state management, memory, agentic RAG, and reasoning effort controls for balancing cost, latency, and capability. Each section addresses how agentic systems integrate with the existing applications and services, while remaining reliable, controllable, and observable under production conditions. The final section moves from prototype to production, covering scaling, security, evaluation, testing, monitoring, and autonomous AI systems. By the end of the book, you will design, deploy, and govern agentic AI systems with the architectural discipline and operational confidence that production environments demand.
