Demystifying the LLM Tech Stack: Tokens, Embeddings, Attention, and Fine‑Tuning
This article walks through the full LLM pipeline—from tokenization and embedding to transformer attention, pre‑training, instruction tuning, RLHF, inference, context windows, Retrieval‑Augmented Generation and agents—explaining each component, its role, and the engineering challenges such as hallucination and safety.
