How many AI training roles are open?

6,008 on 72 platforms as of 3 November 2026.

What does "same platforms" mean?

The 32 platforms read on the first day of tracking (20 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.

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, which moves with hiring alone.

All roles listed, and the platforms read since the first day, which move only when hiring does

The number of roles we list went from 3,910 on 20 Oct to 6,008 on 3 Nov (+53.7%), but most of that is platforms added to the site. On the platforms read since the first day, openings went from 3,910 to 3,920 (+0.3%).
