Key findings
- 1
Law, Medicine & Finance was the largest kind of AI training work, with 1,463 of 4,352 open roles (33.6%) on 18 Oct 2026.
- 2
Between 21 Sep 2026 and 18 Oct 2026, on the platforms tracked throughout, Law, Medicine & Finance grew fastest, from 627 to 861 open roles (+37.3%); Robotics & Physical-AI Data shrank the most, from 31 to 10 (-67.7%).
- 5
Roles removed during the window had been listed for a median of 33.2 days, from 25.6 days for Agentic Tasks & RL Environments to 66.6 for Multilingual & Localization.
- 6
27.0% of open roles accept applicants from any country; residents of United States (3,002), India (1,887) and United Kingdom (1,834) could apply to the most.
Figure 1
Open roles by kind of work
What kinds of AI training work are platforms hiring for, and which are growing?
Sample. 4,352 roles open at the end of 18 Oct 2026 and 2,605 at the start of 21 Sep 2026, across the 36 platforms whose public job boards AITraining.jobs reads daily and that had open roles on 18 Oct 2026.
A role counts as open on a day if it was listed by then and was still in its platform's feed that day.
Change compares the same platforms at both ends. SuperAnnotate (SME), OneForma, Turing, Weekday, Rise Data Labs, Anyone AI, Sovrano AI, RemoExperts, Pasiflora AI, Babel Audio, Volga Partners, Vetto, Scale AI Human Frontier Collective, Innodata, Claru, Perle Labs, Lifted (Upwork) and Pila8 were first tracked during the window and are counted in the end total (1,526 roles) but not in the change.
Change is marked as a small sample where fewer than 30 roles were open at the start.

New and removed listings by kind of work
Where is new hiring happening, and where are roles being taken down?
| Kind of work | New listings | Removed |
|---|---|---|
| Law, Medicine & Finance | 858 | 628 |
| Multilingual & Localization | 586 | 459 |
| Transcription, Audio & Speech | 250 | 202 |
| AI Evaluation & Rating (RLHF) | 169 | 279 |
| Coding & Software Evaluation | 140 | 206 |
| Math & STEM | 100 | 116 |
| Data Annotation & Labeling | 91 | 101 |
| Agentic Tasks & RL Environments | 69 | 75 |
| Writing & Content | 46 | 57 |
| Red-Teaming & AI Safety | 35 | 55 |
| Research Studies & Surveys | 33 | 14 |
| Robotics & Physical-AI Data | 24 | 46 |
Sample. 2,401 roles newly listed and 2,238 removed, from 21 Sep 2026 to 18 Oct 2026, across the 36 platforms whose public job boards AITraining.jobs reads daily and that had open roles on 18 Oct 2026.
New listing: a role first seen in the window on a platform already tracked before that week. A platform's first week in this dataset is its back catalogue, not new hiring, and is left out.
Removed: a role that left its platform's feed during the window. Platforms do not say whether a removed role was filled, paused or closed.
Net change can differ from the change in open roles: a role newly listed and removed inside the window counts in both columns.

How long does an AI training role stay open before it comes down?
| Kind of work | Median days listed |
|---|---|

| Research Studies & SurveysSmall sample | 1.9 |
Sample. 2,177 roles removed from 21 Sep 2026 to 18 Oct 2026 whose listing date is known.
Days listed: from the listing date the job board states (or the first day the role appeared in the feed) to the last day it was seen.
Medians resting on fewer than 30 removed roles are marked as a small sample.

Sample. Listings on the 36 platforms whose public job boards AITraining.jobs reads daily and that had open roles on 18 Oct 2026, 27 Jul 2026 to 18 Oct 2026, by ISO week (Monday to Sunday, UTC).
Each platform's first week in this dataset is left out of new listings (its back catalogue).

Where applicants may live
How many AI training roles are open to applicants anywhere in the world?
| Location rule | Open roles | Share |
|---|---|---|
| Open worldwide | 1,162 | 26.7% |
| Worldwide except listed countries | 344 | 7.9% |
| Only listed countries | 2,831 | 65.1% |
| No rule stated | 15 | 0.3% |
Sample. 4,352 roles open at the end of 18 Oct 2026.
The rule is read from each posting's location text, then, where that names no country, from what the posting's own description states, and where both are silent from what the platform states about where it hires.

Open roles a resident of each country can apply to
Which countries can apply to the most AI training roles?
Sample. 4,352 roles open at the end of 18 Oct 2026; the 20 countries with the most.
A country's count is the roles open worldwide, plus roles whose list names the country, plus roles whose exclusion list does not, the job board's own rule.
15 roles state no location rule; like the job board, they count as open to every country.
Only countries that some posting names are listed. A resident of any other country can apply to the worldwide roles in the first row.

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:
10,301 roles tracked, each with its history
Every role on 36 job boards, read daily since 13 Jul 2026: its pay and place, and the first and last day it was open.
7,464 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.

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