A fast exam on how LLMs work underneath. Unlike the cloud exams, it barely cares about products. It suits engineers who picked up LLMs through APIs and want to fill the theory gap, and the one-hour limit means you need to know it, not look it up.
Take it if
You want the theory behind LLMs, regardless of cloud.
Skip it if
You can already explain attention, embeddings and quantization. Go to the professional level.
Before you start
Check yourself against this list first. If something is missing, close that gap before you pay for an exam.
A basic understanding of generative AI and LLMsNVIDIA's only stated prerequisite. Python helps.
Sampling settings, and how experiments are designed.
Python tooling for ML, and data analysis basics.
Bias and trustworthy AI.

Lesson 1 of 3, 30% of the exam
How transformers work
The largest domain.
Attention
Weighs how each token relates to the others.
Positional encoding
Adds word order, which attention alone lacks.
Embeddings
Vectors that capture meaning.
From text to tokenA simplified view of one prediction.

Common trap
Memorizing terms without being able to explain them.
