Sample. 1,528 of the 3,668 roles open at the end of 17 Oct 2026 name a field in their title; 17 fields are named. New listings from 20 Sep 2026 to 17 Oct 2026.

A role counts for a field when its title names the profession or discipline (for example 'Hospitalist', 'Litigation Attorney', 'Mechanical Engineering Expert'). Generic titles ('Expert', 'Specialist', 'AI Tutor') name no field and are not counted. A role naming two fields counts for both.

Change compares open roles at the start and the end of the window on the platforms tracked throughout; it is marked as a small sample under 10 roles at the start.

Sample. Apply clicks on AITraining.jobs on roles naming each field, from 20 Sep 2026 to 17 Oct 2026, against the days those roles were open.

Clicks per role a week = apply clicks / (open role-days / 7). Index 1.00 is the average across every open role on the site.

Rows with fewer than 30 clicks or 3 roles open on an average day are marked as a small sample.

AITraining.jobs shows visitors the roles open in their country first, which affects roles limited to some countries.

Sample. Roles open on 17 Oct 2026, by the platform that lists them.

A high share means one platform holds most of the openings: an applicant has few alternatives, and that platform sets the going rate.

Sample. Roles open on 17 Oct 2026; shares of each field's own open roles.

The rule is read from each posting's location text and, where that names no country, from what the posting's own description states. The rest of each row is roles open worldwide except some countries, or with no rule stated.

For labs, data vendors and researchers

Buy the data behind this report

The figures above are a summary. Behind them are records we collect ourselves, every day:

  • 9,572 roles tracked, each with its history

    Every role on 29 job boards, read daily since 13 Jul 2026: its pay and place, and the first and last day it was open.

  • 6,200 apply clicks in 28 days

    Which roles people actually apply to, by field, pay and kind of work. It happens on this site, so nobody else can count it.

  • 39 lab and vendor hiring boards

    The job boards of 25 AI labs and 14 human-data vendors, read every day: who is hiring for human data, and who is hiring to buy it.

What you can buy

  • The records

    The rows behind any figure, with their history, not only the totals.

  • A regular feed

    The same figures every week or month, as files.

  • A custom cut or benchmark

    Your countries, languages or fields, or your own platform against the market.

Method and definitions

The public job boards of the AI training platforms this site tracks, read every day. Fields are read from role titles; apply clicks are made on AITraining.jobs. Every figure is computed by one database query over the window shown, the same query for the live report and for every edition. Each figure states its sample beneath it.

Field of a role
A role counts for a field when its title names the profession or discipline, for example 'Hospitalist', 'Litigation Attorney' or 'Mechanical Engineering Expert'. Generic titles ('Expert', 'Specialist', 'AI Tutor') name no field. A role naming two fields counts for both.
Open role
A role listed by a given day and still in its platform's feed that day.
New listing
A role that first appeared during the window on a platform already tracked before that week. A platform's first week in this dataset is its back catalogue and is not counted as new.
Advertised pay
The hourly figure a posting states (the middle of a stated range). Medians need at least 8 roles stating a rate; the middle half runs from the 25th to the 75th percentile.
Clicks per open role a week
Apply clicks on AITraining.jobs divided by the days the roles were open, times 7.
Demand index
A group's clicks per open role a week divided by the same rate across every open role on the site. Above 1, its roles draw more applicants than the average role.
Location rule
Read from each posting's location text and, where that names no country, from what the posting's own description states: open worldwide, worldwide except listed countries, only listed countries, or no rule stated.
Window
Live: the last 28 complete days, in UTC. Edition: one calendar month, in UTC.

What this data cannot tell you

  • Platforms that recruit without a public job board are not counted. Several large ones invite workers to projects directly.
  • A listing is not a hire. Some platforms keep evergreen roles open for months, and some post one listing per language or country.
  • Generic titles hide the field of many roles, so each field's count is a floor.
  • Apply clicks measure interest among the people who use AITraining.jobs, and what is shown first gets clicked more.

How the job feeds are read and roles are classified: site methodology. How fresh, complete and consistent the data is, checked every day: data quality and coverage.

Editions

The live report covers the last 28 complete days and changes every day. Each complete month is also published as an edition, frozen two days after the month ends, so a figure you cite from an edition never moves.
