Measured statements
In development Written by fixed rules from this reading’s stored figures. No model writes them.
On Reddit, 63 distinct people posted about OpenAI o-series between 7 and 13 September 2026: 74 posts, an estimated 0.02% of that week's Reddit posts about AI, leaving out spam, bot, incentive and templated automated posts (100.0% of these posts had an identifiable author).
Reddit · 7–13 Sep 2026 · author coverage 100.0% · 7 days: 7 backfilled
5 more statements withheld. No posts about OpenAI o-series on Hacker News between 7 and 13 September 2026. No posts about OpenAI o-series on arXiv between 7 and 13 September 2026. Withheld for platforms not counted this week: Bluesky, Google News and Exa.
What this reading rests on
| Platform | Days counted | How the posts were collected |
|---|---|---|
| 7 of 7 | Loaded afterwards from an archive | |
| Hacker News | 7 of 7 | Loaded afterwards from an archive |
| arXiv | 7 of 7 | Loaded afterwards from an archive |
Not counted: Bluesky, YouTube, Google News and Exa, not being collected yet.
A day counts once it has settled: once the posts still expected for it are below the threshold, or, for posts loaded afterwards from an archive, once they’re loaded. Coverage day by day is in this reading’s conditions. How coverage is recorded.
This reading was made with methods that are still being validated. Every figure says which state it’s in.

OpenAI o-series in each platform’s table
Where OpenAI o-series sits among every ranked subject on each platform. The heavy mark is OpenAI o-series; every thin mark is another subject.
#29 of 42 on Reddit63 people · Claude 9,248 (#1)
42 ranked subjects, each a tick on Reddit’s own people scale, 0 to 9,248. 43 more subjects aren’t ranked: their people figures are hidden (n 0–18 people, below the threshold of 20), so they aren’t drawn.
Not ranked on Hacker News: n 0 people, below the threshold of 20 people.
Distinct people who posted about each subject on each platform, 7–13 Sep 2026, as of 25 Sep 2026 13:30Z, from release 2026-W37’s summary table (published). Each strip is on its own scale and nothing is added across platforms: one person can post on several. arXiv, Google News and Exa carry articles, which have no authors, so they have no ranking by people.
Attention
How many people posted about OpenAI o-series on each platform, and OpenAI o-series’s share of that platform’s posts. One row per platform, each on its own terms.
n 74 posts · author coverage 100.0% · 7 days: 7 backfilled · sample: 10 posts, one per author
Not counted this week. Bluesky, Google News and Exa have no day in this window that counts, so they have no figures here.
Hacker News. People hidden: n 0 people, below the threshold of 20 people. Share and posts hidden: n 0 posts, below the threshold of 20 posts.
arXiv. People not applicable: arXiv posts are articles, which have no authors, so people aren’t counted. Share and posts hidden: n 0 posts, below the threshold of 20 posts.
In development. Spam, bot and incentive posts were removed with labels that agree with a stronger model at κ 0.74, below the 0.80 needed to drop this mark. The agreement is model-to-model.
Posts published 7–13 Sep 2026, as of 25 Sep 2026 13:30Z; in development. People count distinct platform identities and are never added across platforms. Share is OpenAI o-series’s posts over all posts AIDRAN captured on that platform in the window. Reddit’s posts include its comments. A normal share is openAI o-series's share of each platform's posts in the 14 earlier stored weeks of the same era (2026-W23, 2026-W24, 2026-W25, 2026-W26, 2026-W27, 2026-W28, 2026-W29, 2026-W30, 2026-W31, 2026-W32, 2026-W33, 2026-W34, 2026-W35, 2026-W36), per platform.

The one community this reading stores; the rest of the track is posts in communities it doesn’t list.
Posts about OpenAI o-series by community, 7–13 Sep 2026, as of 25 Sep 2026 13:30Z; in development. Each platform is drawn on its own scale. The word after each community is its type: who is there, not what it’s about (users are people who use one AI product; builders build with AI). A post counts once, in the community it was posted in.

Change compares this reading with the previous stored reading of the same subject, usually last week’s, and both endpoints stay visible with their dates. Each value carries its n; open it for its full conditions, coverage included. Stored weeks, above, cross eras, which marks a change in how weeks were captured: March era weeks were rebuilt from archives, with live capture from 7 Mar to 31 May, Archive backfill weeks were backfilled from archives (Reddit, Hacker News and arXiv only) and September era weeks were captured live from 16 Sep and filled in from archives.
