Module 03

Deterministic Steps versus LLM Steps

By the end of this module you can decide which nodes need a language model and which are ordinary functions, and stop paying for judgement where logic will do.

Units

  1. Unit 03.00: Which decisions need judgement
  2. Unit 03.01: Paying a model to do arithmetic
  3. Unit 03.02: Making an LLM step's output checkable
  4. Unit 03.03: Falling back to code when the model is unsure
  5. Unit 03.04: The cost difference over a thousand runs
