LinkedIn 41% 的長文由 AI 生成 — 實際比例可能更高
pangram 分析了 100 萬條貼文，發現 linkedin 以 41% 的 ai 生成長文比例領先，遠超 x/twitter 和 substack。實際比例可能更高，這標誌著職業資訊流正在受到系統性污染。
a study of 1m posts from april to june 2026 revealed that 41% of long-form posts on linkedin are ai-generated, compared to 10% on substack. linkedin produced the majority of detected ai content despite making up only a third of the total dataset analyzed. the detection model, pangram 3, boasts a 0.01% false positive rate but is likely more accurate at identifying human text than ai text, suggesting the true saturation is higher. this inundation of 'slop' threatens the utility of professional networks and forces platforms to implement automated moderation against generated content.
