Chapter 7: What can a single call do?

A single API call to an LLM can do a surprising amount of useful work:

• Summarization - shrink text while preserving meaning
• Classification - assign labels to text
• Translation - convert between languages or formats
• Extraction - pull structured data from unstructured text
• Evaluation - score content against a rubric
• Rewriting - change tone, style, or complexity

These used to require machine learning expertise, training data, and specialized models. Now they're just API calls.

See the Patterns page for code examples.
