LinkedIn 41% 的长文由 AI 生成 — 实际比例可能更高
pangram 分析了 100 万条帖子，发现 linkedin 以 41% 的 ai 生成长文比例领先，远超 x/twitter 和 substack。实际比例可能更高，这标志着职业信息流正在受到系统性污染。
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.
