Kept about 30 days
Same story
For duplicate reports of the same event, select only the most authoritative report.
Merged reportsOther same-day reports of the story join the event; English and Chinese reports are compared with the event's English and Chinese text. No model is used.
Title + summary TF-IDF similarity ≥ 0.25

Scoring, trends and forecasts

Content analysis

Model
deepseek-v4-flash
Importance bands
9-10
Major global events (major AI model/product releases such as new GPT, Kimi or DeepSeek versions, major geopolitical events, important international conferences such as WAIC, acquisitions or policies that reshape an industry)
7-8
Industry news with broad impact, major policies in important countries, significant moves by well-known companies, highly discussed community stories
5-6
General industry news and regional events
1-4
Minor updates, marketing articles, pure opinion commentary and local news with limited impact
Ranking rules
1
Community picks (top Hacker News stories and the day's hottest Reddit AI posts) reflect what the tech community is sharing: popular stories (for example HN 500+ points) about major topics deserve significantly higher scores; memes, spam and unrelated entertainment still receive low scores.
2
For duplicate reports of the same event, select only the most authoritative report.
3
Prioritize importance without forcing equal numbers in each category.
