In this lesson
Lesson goals
- The model is one component
- Tools, memory, and planning
- Guardrails and human approval
Core idea
The difference between direct answers and systems that plan and use tools.
1. The model is one component: understand it in context, identify inputs and outputs, and define how the result will be verified.
2. Tools, memory, and planning: understand it in context, identify inputs and outputs, and define how the result will be verified.
3. Guardrails and human approval: understand it in context, identify inputs and outputs, and define how the result will be verified.
