LLM Architecture & Transformers Certification

The definitive deep-dive into how large language models actually work

Key facts

About the LLM Architecture & Transformers certification

A professional-grade certification covering the complete anatomy of decoder-only large language models. You will reason precisely about tokenization and byte-pair encoding, embeddings and weight tying, positional encodings (sinusoidal, learned, RoPE, ALiBi), the mathematics of scaled dot-product and multi-head attention, KV-caching and long-context techniques such as FlashAttention, sliding-window attention, and grouped-query attention. The exam tests deep, current understanding of normalization placement, activation functions, mixture-of-experts, numerical precision, scaling laws, and sampling — at the level expected of an ML engineer who builds and debugs transformer models in production.

What you will learn

The official LLM Architecture & Transformers study course covers:

  1. Inputs: Tokenization, Embeddings & Positional Encoding — How raw text becomes the position-aware vectors a transformer consumes.
  2. The Attention Mechanism — Scaled dot-product attention, causal masking, multi-head, and the long-context toolkit.
  3. The Transformer Block & Stack — Residuals, normalization, the feed-forward network, and stacking N blocks into a decoder.
  4. From Logits to Text & Scaling — Logits, softmax, sampling strategies, precision, scaling laws and mixture-of-experts.
  5. Hands-on Lab — Build a Transformer From Scratch — A from-scratch capstone in Google Colab: implement token + positional embeddings, self-attention with a causal mask, a complete transformer block, th…
