🚀 From Transformers to AI Agents: The Complete Engineering Guide to Modern AI Architecture (LLMs, RAG, Vector Databases & Agentic Systems)

Most people think ChatGPT is "the AI." In reality, ChatGPT is just one layer of a much larger engineering stack.

Modern AI applications aren't powered by a single model. They're powered by an ecosystem of transformers, tools, retrieval systems, memory, vector databases, orchestration frameworks, and guardrails working together.

If you're a software engineer, understanding how these components fit together is far more valuable than memorizing AI buzzwords.

Why This Matters

The AI industry has shifted dramatically over the last few years.
