But building capable agents requires more than simply calling an LLM API. This book provides a practical introduction to the concepts, architectures and frameworks behind modern AI agents.\u003c\/p\u003e\u003cp\u003eYou'll begin by exploring the evolution of agents and the architectural patterns used to build them. From there, the book covers practical aspects of working with frontier LLMs from OpenAI, Anthropic, Google, xAI and DeepSeek, including API access, authentication, security practices and cost management.\u003c\/p\u003e\u003cp\u003eYou'll then build agent-powered applications using LangChain and LlamaIndex, exploring memory, persistence, structured outputs, selective memory retrieval with BM25, tool integration through the Wikipedia API, and modern approaches to create UIs for agents.\u003c\/p\u003e\u003cp\u003eBy the end of the book, you will: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUnderstand AI agent architectures and design patterns\u003c\/li\u003e\n\u003cli\u003eLearn LLM API fundamentals, security practices and cost control\u003c\/li\u003e\n\u003cli\u003eAccess models from OpenAI, Anthropic, Google, xAI and DeepSeek\u003c\/li\u003e\n\u003cli\u003eBuild agent applications with LangChain and LlamaIndex\u003c\/li\u003e\n\u003cli\u003eAdd memory, persistence and structured outputs to agents\u003c\/li\u003e\n\u003cli\u003eImplement selective memory retrieval techniques using BM25\u003c\/li\u003e\n\u003cli\u003eExtend agent capabilities through external tools and APIs\u003c\/li\u003e\n\u003cli\u003eBuild interactive agents with modern UIs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":47968816824471,"sku":"9798199319348","price":1672.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9798199319348.webp?v=1782919496","url":"https:\/\/atlanticbooks.com\/products\/agent-essentials-architectures-frameworks-and-applications-9798199319348","provider":"Atlantic Books","version":"1.0","type":"link"}
