Large Language Models in Practice

Like Duolingo, but for Large Language Models in Practice. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Precision Control, The Mechanics of Meaning, Customization and Integration, and Reliability and Safety. It assumes you already know the basics.

Key ideas in Large Language Models in Practice

  • Few-shot examples provide a template that the LLM mimics for formatting and tone
  • The model uses the relationship between input and output in examples to infer the desired logic
  • Chain-of-Thought forces the model to calculate intermediate steps before committing to a final token
  • Externalizing reasoning reduces the likelihood of the model hallucinating a quick but wrong answer
  • How few-shot examples establish a pattern for the LLM to follow
  • The logical flow of a Chain-of-Thought prompt
  • Delimiters act as boundaries that tell the LLM where instructions end and data begins
  • Structured formats like JSON allow software to reliably extract specific data fields from a response
  • Clear separation prevents the LLM from executing commands hidden inside user-provided text
  • LLMs can be forced into valid syntax by providing a schema or a one-shot JSON example
  • The function of different delimiters in preventing prompt injection
  • LLMs often struggle with negation because 'not' is a single token that can be easily overlooked
  • Providing a positive alternative gives the model a clear high-probability path for the next token
  • The necessity of structured output for programmatic integration
  • The effectiveness of positive paths over negative constraints
  • System messages act as a persistent instruction layer that overrides user-level prompts.
