Reasoning vs non-reasoning models
For three years the magic phrase was "let's think step by step". With today's reasoning models it mostly just adds tokens to your bill. What replaced it is simpler, and it changes how you write prompts.
In this lesson you'll learn to
- Explain chain-of-thought prompting, why it worked, and where it still helps.
- Decide which tasks are worth a reasoning model or higher effort, and which aren't.
- Write prompts for reasoning models that state goals and success criteria instead of steps.
- Explain why a model's written reasoning isn't a reliable record of how it reached an answer.
