HN 上有多少内容是 AI 生成的?
How much of HN is AI?

作者审视了自己与 Hacker News (HN) 之间爱恨交织的关系,指出它既是重要的流量来源,也是有毒言论的集散地。然而,作者最主要的担忧是该网站充斥着越来越多的 AI 相关内容。 通过对 2026 年初该网站头条新闻的系统性抽样,作者记录了 AI 内容主导地位的急剧上升。二月份,大多数日子的头五篇推文中都有 AI 主题;到了六月,每日列表中约有 50% 到 60% 的内容要么聚焦于 AI,要么可能是由 AI 生成的。 为了识别 AI 撰写的内容,作者使用了“Pangram”——一种旨在识别大语言模型(LLM)常见准确定性风格模式的检测工具。在通过人工审核验证结果后,作者得出结论:该平台正在经历深刻的转变,“AI 自我审视”和机器生成的文本已成为其每日信息流的标准特征。

Hacker News 上的讨论帖“Hacker News 有多少内容是 AI 生成的?”揭示了社区内部对于该网站日益向 AI 中心化话语倾斜的日益严重的隔阂。许多长期用户感到沮丧,因为与 AI 相关的内容——无论是真实新闻、厂商营销还是 AI 生成的“垃圾信息”——已成为该平台的主流,且往往显得单调乏味。 讨论的主要要点包括: * **内容饱和:** 用户估计目前 50% 到 60% 的头条文章都与 AI 有关。一些人认为这是几十年来最重大技术变革的必然反映,而另一些人则认为这是该网站历来兼容并蓄的“黑客”精神的退化。 * **“AI 检测器”带来的疲劳:** 一个反复出现的争议点是“AI 检测器”(包括自动化工具和人工判断)的泛滥。它们经常且往往错误地指责作者使用 AI,从而导致了不必要的戾气。 * **社区转变:** 许多资深用户认为,网站文化已经从亲自动手的工程实践转向了更愤世嫉俗、以市场为导向的心态。这导致一些人为了寻找更高质量、以人为本的交流而迁移到 *Lobsters* 等“围墙花园”式社区。 * **审核挑战:** 虽然版主在积极标记机器人活动,但社区对于目前的饱和状态究竟是自然演变,还是行业内部人工制造、操纵舆论的副产品,仍存在分歧。

I have a complicated relationship with Hacker News. The site is the most important aggregator of geek news and a major source of traffic to this blog. At the same time, it has a fair number of toxic commenters, making it a dependable source of insults hurled in my general direction; if you want a taste, this article has been called “watered-down” and “slop”.

The site is run by geeks and for geeks, so it’s not immune to tech trends; for example, around 2018, it had a fair number of stories focused on cryptocurrencies and NFTs. That said, the recent shift feels more profound: almost every day, it feels that the lineup is dominated by stories focused on AI, written by AI, or commented on by AI.

That images shows a particularly bad day, so to give a more honest assessment, I also performed a more systematic survey in February 2026, and again in June of the same year.

To get a sense of how much of the feed is occupied by AI-related topics, I took a sampling of the daily top #5 for all of February:

AI took four out of five spots on Feb 4 and Feb 12, plus arguably the entire line-up on Feb 5 (story #3 was submarine marketing for an AI vendor). The only days without LLM news in the top 5 were February 1 (with the first AI story at #7, then #9), February 9 (first at #8), and February 25 (with AI at #6, #9, #10).

For the second part of the experiment — figuring out which stories were likely AI-written — I tapped into Pangram. Pangram is a remarkably good, conservative model for detecting LLM-generated text. These detectors have bad rap among techies, but the objections are often based on outdated assumptions or outright misconceptions. For the tools to work, AI writing doesn’t need to be in any way “inhuman”. It’s enough that the default voice of the current crop of LLMs is quasi-deterministic: ask for the same essay twice and you’ll get a stylistically similar result. The individual mannerisms are human-like, but it’s very unlikely that your writing combines the exact same set. I write about it a bit more here.

To validate the results, I also reviewed all the flagged stories and I think the findings make sense; if anything, Pangram had a couple of false negatives. To give you a sense of what was flagged, have a look at the #3 story on February 19 (“AI is not a coworker, it’s an exoskeleton”). It had 500+ upvotes and 500+ comments. In my opinion, it has a wide range of red flags.

In June, to capture more detail, I used solid black for pure-play AI navel-gazing (vendor announcements, op-eds about the benefits or drawbacks of the technology, etc) and hatched shapes for stories that lean heavily into AI, but have broader ramifications (e.g., the Instagram AI support agent account hack). As before, stories that are only tangentially related to AI (e.g., reports of RAM price hikes) are not flagged.

In the first half of the month, roughly 60% of the daily HN lineup was AI-related or AI-generated, tapering off to ~50% as we approached the end of the month. This is up from 40% in February.
