AI Training Hiring Activity

Method and definitions

The public job boards of the AI training platforms this site tracks, read every hour. 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.

Coverage

The platforms whose public job boards AITraining.jobs reads in full every hour. Each figure states how many were read.

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. When this site changes how it reads a platform's board (a cap lifted, a page kind or department read too, a relevance rule changed), the roles that came into view or left it from that change to the end of its week are this site's reading, not the platform's hiring: they are not new listings or removals, and changes in open roles are measured like for like across it. Each platform's report says what changed.

Removed listing

A role that left its platform's feed during the window.

Days listed

From a removed role's listing date to the last day it was seen in its feed.

Kind of work

Each role is classified from its title and description into one of the twelve kinds of AI training work this site tracks, from AI evaluation and coding to multilingual and audio work. Every kind links to its own page.

Listing date

The date the platform's job board gives for the posting, or else the first day the role appeared in the feed. A role that arrived with a platform's back catalogue, or came into view with a change in how this site reads its board, and gives no date has no known listing date.

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.
• A removed listing may have been filled, paused or closed: platforms do not say which.
• Duplicate postings of the same role are merged when the feeds are read.

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.
