The original title is "Engineering Guide to Modern AI Architecture: Transformers, LLMs, RAG, and Agentic Systems"

Short summary

A comprehensive engineering guide tracing the evolution from transformers to agentic AI systems, covering LLMs, tokenization, context windows, tool calling, RAG, and vector databases. It explains how modern AI applications are built as ecosystems of interconnected components rather than single models. The guide is aimed at software engineers who need to understand the full AI engineering stack.

• •Explains the full AI engineering stack from transformers to agents
• •Covers LLMs, tokenization, temperature, context windows, tool calling, and RAG
• •Positions agentic AI as the third wave after chatbots and copilots
