Module 1

What an LLM Is

Getting to know the models: how they produce answers and why they get things wrong.

What a Large Language Model Is

We unpack what an LLM is, how it 'thinks', and why its answers are statistics rather than knowledge.

15 min

Context, Memory, and Tokens

We unpack what context is, how tokens are counted, and why the model 'forgets' the start of a conversation.

Module 2

Where the Model Breaks

Understanding the limits of LLMs and how to work with them.

Model Limits and Hallucinations

Which classes of tasks LLMs handle poorly, how to spot hallucinations, and how to reduce them.

15 min

Which Model to Choose for the Task

A simple framework for choosing a model: context length, cost, privacy, task specifics.
