## When to prefer this

Choose this endpoint when you need a structured, key-point-oriented summary from long-form text such as articles, reports, or transcripts. It is especially useful when you want a concise digest with an explicit word cap. Prefer this over generic LLM summarization when you need consistent structured output and are willing to pay per-call for reliability and formatting guarantees.

## Known failure modes

- Extremely long inputs may exceed token limits and return a truncation or error response
- max_words set too low may result in incomplete or overly vague summaries
- Non-textual or binary input returns a parsing error
