Open AI training roles over time

How many paid AI training roles are open, in total, by field and by platform, at every hourly update.

Every role re‑checked hourly Last updated 21 October 2026

Total openings

The total counts every open role we list. It rises when we add a platform as well as when platforms hire, so the second chart tracks only the platforms read since the first day: that one moves with hiring.

The number of roles we list went from 3,910 on 19 Oct, 22:56 to 5,303 on 21 Oct, 09:42 (+35.6%), but most of that is platforms added to the site. On the platforms read since the first day, openings went from 3,910 to 3,965 (+1.4%).

  1. 20 Oct: 9 new sources added to the site (Crossing Hurdles, iMerit Scholars, RWS TrainAI, Datamundi and 5 more), +160 roles
  2. 21 Oct: 11 new sources added to the site (Lifted, an Upwork Company, Aptura, Lilt, HumanSignal and 7 more), +1,180 roles

Roles open on the platforms' own job boards at each hourly update, paid research studies left out. Numbered markers show when platforms were added to the site, which raises the total without any change in hiring.

Open AI training roles over time: common questions

How many AI training roles are open?

5,303 on 52 platforms as of 21 October 2026.

What does "same platforms" mean?

The 32 platforms read on the first day of tracking (19 October 2026). Counting only those means the line moves with hiring, not with us adding platforms to the site.

How often is this updated?

Every hour, from the platforms' own public job boards.
