The Hitchhiker's Guide to Agentic AI arxiv.org
Haggai Roitman’s practitioner’s guide to agentic AI, covering the whole stack on the argument that building good agentic systems requires understanding every layer: transformers, GPU infrastructure and training at the bottom, then alignment and reasoning (RLHF, DPO, chain of thought), RAG and memory architectures, agent design patterns, multi-agent coordination, and evaluation and deployment at the top. Each chapter pairs theory with code examples and references. Bookmarked as a reference to dip into rather than read cover to cover.
