Lesson Guide

Different models fit different jobs

Fast models are useful for simple classification and drafting. Strong reasoning models are better for complex analysis. Coding models help with software tasks. Multimodal models can work with images or documents.

  • Simple tasks need speed.
  • Complex tasks need reasoning.
  • Media tasks need multimodal support.

Tradeoffs matter

Model choice affects response time, cost, quality, and reliability. A workflow should not always use the largest model if a smaller one can do the task well.

  • Measure latency.
  • Track token usage.
  • Review quality samples.

Design a fallback

When a model is slow, unavailable, or too expensive for a task, use a backup model or send the task to human review.

  • Fallback model
  • Retry rule
  • Human review path

Practice Task

List five AI tasks and choose a model type for each: fast, reasoning, coding, multimodal, or human review.

Ready Checklist

  • The selected model matches the task.
  • Cost and speed are considered.
  • There is a fallback plan.
