Show HN 帖子的比例在增加，但它们的得分在下降。
The percentage of Show HN posts is increasing, but their scores are decreasing

## Hacker News & LLM 数据分析对 Hacker News 数据的分析显示，“Show HN”帖子数量与大型语言模型 (LLM) 的兴起同时增加。历史上，“Show HN”帖子约占故事的 2-3%，而截至 2025 年 12 月，这一比例已超过 12%，与 Claude Code 和 Cursor 1.0 等进展相关。然而，虽然“Show HN”帖子的*数量*有所增加，但它们的*质量*（按平均得分衡量）却有所下降。过去，“Show HN”帖子的得分与普通故事相似（15-18 分），现在平均约为 9.04 分，而所有故事的平均分为 19.53 分。作者推测，这一下降不一定是因为 LLM 生成的项目质量较低，而是可能由于“Show HN”帖子数量增加导致的用户疲劳。确定哪些帖子是 LLM 生成的仍然是一个挑战，因为许多创作者没有披露其使用情况。用于此分析的数据和代码可在 GitHub 上公开获取 ([https://github.com/plastic041/hackernews](https://github.com/plastic041/hackernews))。作者计划定期更新分析。

最近在Hacker News上观察到“Show HN”（展示如何做）帖子的数量有所增加，但平均得分却在*下降*。用户推测这并非仅仅因为数量增加，可能反映了“疲劳”——特别是当前大量人工智能相关项目涌现。一些评论者分享了在Show HN上发布项目却几乎没有互动的情况，暗示好的想法可能被淹没在信息噪音中。一位用户指出，在使用`showdead`选项时，看到更多Show HN帖子被标记为“已死”。总体情绪表明，通过此渠道分享的项目数量增加的同时，质量可能也在下降。

Last update: 2026-01-14

Recently, I felt like I was seeing more “Show HN” stories, and many of which were generated with LLMs. So I analyzed the data to see if that was true. Also I included the average score per month to see if people enjoy seeing them (because I don’t :P).

Charts

Stories in 2026 was omitted. 1) It’s only 13 days, 2) Scores are not stable yet.

Left axis: show_hn_ratio(show_hn / story * 100)

Analysis

Disclaimer: I am neither a data scientist nor a statistician. Some nuances may have been lost in translation.

Percentage

For about ten years (2012~2022), the percentage of Show HN stories was around 2-3%. Then, with the appearance of LLMs that can code, it’s been increasing. Claude Code and Cursor 1.0 accelerated it even more. As of December 2025, over 12% of all stories are Show HNs. It’s safe to say that there is a correlation between the increase in Show HN posts and LLM. People can create great things even if they don’t know how to code at all.

Scores

Show HN stories used to receive similar scores (around 15-18) to those of all stories until 2023~2024. However, it’s been declining while percentage of them are going up. As of December 2025, the average Show HN score is 10 points lower (9.04 vs 19.53).

Does it mean LLM-generated Show HNs are lower quality? I’m not sure. Maybe people are tired of seeing too many Show HNs.

Also I have no idea why the average score was increased in 2022. A lot of new users?

Data and codes

You can find python code and csv in https://github.com/plastic041/hackernews.

I exported BigQuery hacker news data to csv using this query:

SELECT
  `time`,
  `title`,
  `type`,
  `score`,
  `id`
FROM
  `bigquery-public-data.hacker_news.full`
WHERE
  (`type` IN ('story')) and title IS NOT NULL;

The type field in BigQuery does not have a show_hn attribute like the Algolia API, so I lowercased titles and filtered using starts_with("show_hn: ") to determine if a post is a Show HN story.

I didn’t commit to the repo the original CSV because it was too big (~400 MB) but you can download it from BigQuery for free (I didn’t set billing account). I ran SQL above, exported it to google drive, and downloaded it.

I would like to analyze the percentage of Show HN stories generated with LLMs but I couldn’t find the way to do this, because many Show HN stories don’t mention that they’ve used LLMs in their text.

I’ll try to update this article every few months.
