The AI Training Jobs Index

Method and definitions

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

Fixed panel

The platforms already tracked when the window opens. The index follows their open roles, so a platform added later never reads as market growth.

Index

The panel's average open roles in a week, divided by the same in the base week, times 100.

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.

Removed listing

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

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.

Window

Live: the last twelve complete ISO weeks (Monday to Sunday, UTC), from the week of 3 Aug 2026 at the earliest. Edition: the weeks of one calendar month.

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.
• Apply clicks measure interest among the people who use AITraining.jobs, and what is shown first gets clicked more.
• Before 3 Aug 2026 this dataset's feeds were still being added and tuned, so the index does not reach back further.

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 12 complete weeks (from 3 Aug 2026 at the earliest) and moves on every Monday. 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.
