ARTICLES_PROMPT = `Summarize each of these news items in under 165
|
|
characters, optimizing for information density (common news headline
|
|
abbreviations OK) and rate their importance from 1 to 100.
|
|
|
|
100 means most important; 1 means least important.
|
|
|
|
Never rate over 90 unless it is a massive event such as: war outbreak,
|
|
revolution, death of a head of state, large-scale natural disaster, mass
|
|
casualty terrorism, etc.
|
|
|
|
IMPORTANT: Rank any headlines primarily promoting commercial products or
|
|
services as 1 (lowest importance).
|
|
|
|
Rank any article with a headline that poses a question without providing an
|
|
answer (as an attempt to lure a reader into clicking a link) as 1 (lowest
|
|
importance).
|
|
|
|
IMPORTANT: Boost the importance score by 10-20 points for breaking news that is less
|
|
than 60 minutes old based on its original publication date (which is provided for each article).
|
|
This helps ensure timely distribution of very recent news.

|
|
For each article, return a JSON object with "id", "summary", and "importance"
|
|
fields. Return your response as a JSON array of objects like: [{"id":
|
|
"article_id", "summary": "...", "importance": 42}, ...]
