Key findings

  1. 1

    Between the week of 5 Oct 2026 and the week of 19 Oct 2026, open roles in AI Evaluation & Rating (RLHF) on the platforms tracked since 1 Oct 2026 went down 24.2%, from about 131 to 100, like for like across the changes in how this site reads some of their boards, against -3.1% for all AI training work on the same platforms; platforms first tracked later, left out of this panel, listed about 93 more in the week of 19 Oct 2026.

    Figure 1
  2. 2

    33 platforms listed the 207 open roles in AI Evaluation & Rating (RLHF); Outlier (Scale AI) held 44 of them (21.3%) and the three largest 89 (43.0%) (HHI 904, unconcentrated, against 522 for all AI training work).

    Figure 3
  3. 3

    133 of the 207 open roles in AI Evaluation & Rating (RLHF) (64.3%) stated an hourly rate, with a median of $35/hr (typical pay $20 to $120), 13% below the $40/hr of all AI training work.

    Figure 4
  4. 4

    Each open role in AI Evaluation & Rating (RLHF) drew 4.21 apply clicks a week on AITraining.jobs, 1.23x the average AI training role: the 3rd highest of 12 kinds of work whose demand reads on its own.

    Figure 6
  5. 5

    23 of the 207 open roles in AI Evaluation & Rating (RLHF) (11.1%) accepted applicants from any country, against 18.5% of all AI training roles; of the 20 countries compared, residents of the United States (171), India (82) and the United Kingdom (75) could apply to the most, and residents of Palestine to the fewest (54).

    Figure 9
  6. 6

    The words used most in the titles of open roles in AI Evaluation & Rating (RLHF) were Evaluator or reviewer (54), Lead or manager (32) and Quality assurance (29), of 207 open roles.

    Figure 10
  7. 7

    Of the 198 open roles in AI Evaluation & Rating (RLHF) with a full description, 46 (23.2%) mention a PhD or master's degree, 5 (2.5%) a professional credential and 77 (38.9%) an assessment or test; the 57 stating years of experience ask for a median of 3 years.

    Figure 11
  8. 8

    Over the 31 days from 1 Oct 2026 to 31 Oct 2026, open roles in AI Evaluation & Rating (RLHF) on the platforms tracked at its start went down 43.5% (178 to 101, like for like across the changes in how this site reads some of their boards): platforms listed 110 new roles and removed 228, and a removed role had been listed for a median of 30 days (30 across all AI training work).

Sample. Average open roles in AI Evaluation & Rating (RLHF) over each week's days, on the 18 platforms tracked since 1 Oct 2026 (the fixed panel; 16 of them list this work), 1 Oct 2026 to 31 Oct 2026.

The index is the panel's open roles against the week of 5 Oct 2026 (100), chained week to week, beside the same index for all AI training work on the same platforms.

This site changed how it reads 6 platforms' boards in this span (Alignerr on 14 Oct 2026; Mindrift on 14 Oct 2026 and 22 Oct 2026; OpenTrain AI on 14 Oct 2026; Handshake AI on 14 Oct 2026; Prolific on 18 Oct 2026; Outlier (Scale AI) on 30 Oct 2026). From each change to the end of its week the roles that came into view are counted as already listed, not as new listings, and the roles that left view are not counted as removals; changes in open roles are measured like for like across it, on the roles that did not move with it. Each platform's own report says what changed.

Perle Labs (first tracked 10 Oct 2026), SuperAnnotate (SME) (first tracked 10 Oct 2026), Turing (first tracked 10 Oct 2026), RemoExperts (first tracked 10 Oct 2026), Sovrano AI (first tracked 11 Oct 2026), Anyone AI (first tracked 11 Oct 2026), Vetto (first tracked 14 Oct 2026), OneForma (first tracked 14 Oct 2026), Claru (first tracked 14 Oct 2026), Weekday (first tracked 18 Oct 2026), Innodata (first tracked 18 Oct 2026), Rise Data Labs (first tracked 18 Oct 2026), Lifted (Upwork) (first tracked 18 Oct 2026), Scale AI Human Frontier Collective (first tracked 18 Oct 2026), Anthropic (first tracked 21 Oct 2026), DataAnnotation (first tracked 22 Oct 2026), TELUS Digital AI (first tracked 22 Oct 2026), iMerit (first tracked 22 Oct 2026), RWS TrainAI Community (first tracked 22 Oct 2026), EvolutionIQ (first tracked 29 Oct 2026) and JazzX AI (first tracked 29 Oct 2026) list this work but were added to the dataset later, so they are left out of the panel and counted only in the last column: a platform's arrival never reads as growth.

Weeks cut by the span, or with fewer than 14.4 open roles on the panel (the weight of the rest of AI training work's change, fitted on the two: below it the market's movement says more than the kind's own roles), are marked.

Sample. Roles listed from 1 Oct 2026 to 31 Oct 2026: 482 in AI Evaluation & Rating (RLHF), 7,396 across all AI training work.

Change compares the roles open on the first and the last day of the window on the platforms tracked when it opened, so a platform added during the window does not read as growth.

The kind's change reads on its own (not marked) from 9.8 roles open at the start: the weight of the rest of AI training work's change, fitted on the two.

A new listing first appeared in the window on a platform already tracked before that week; a platform's first week (its back catalogue) is not counted.

Median days listed runs from a removed role's listing date to its last sighting, for removed roles with a known listing date (at least 3; 223 here).

Sample. 207 roles in AI Evaluation & Rating (RLHF) open at the end of 31 Oct 2026, by the platform that lists them: HHI 904 (unconcentrated), against 522 for all AI training work.

HHI: the sum of every platform's squared percentage share of the open roles, 0 to 10,000; under 1,500 is unconcentrated, 1,500 to 2,500 moderately and above 2,500 highly concentrated (US merger-guideline thresholds).

Shares are of listings, not of people hired or money paid: a platform posting one role per language or country weighs more here than its hiring may.

A median needs at least 3 roles stating an hourly rate.

Sample. Roles open on 31 Oct 2026: 207 in AI Evaluation & Rating (RLHF), 133 of them stating an hourly rate; 4,381 across all AI training work.

Pay is the hourly figure a posting advertises (the middle of a stated range), counted once per distinct rate as the job board counts it. The median and typical pay are the board's: typical pay runs from the 25th percentile of what roles pay (the middle of each advertised range) to the 90th-percentile advertised ceiling, stated from 3 distinct rates.

Roles paid per task or per project, or that state no figure, do not state an hourly rate.

Sample. Apply clicks on a specific role on AITraining.jobs, from 1 Oct 2026 to 31 Oct 2026: 3,018 on roles in AI Evaluation & Rating (RLHF), against the days those roles were open.

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

AI Evaluation & Rating (RLHF) against every kind of work: Rows with fewer than 3.6 open role-days (0.5 role-weeks) are marked as a small sample and not ranked: below that the pooled rate of the kinds of work weighs more than a row's own clicks (the weight fitted on their own clicks).

Its roles by stated pay, against each other: Rows with fewer than 254.1 open role-days (36.3 role-weeks) are marked as a small sample and not ranked: below that the pooled rate of the two sides weighs more than a row's own clicks (the weight fitted on their own clicks). Its roles by reach, against each other: Rows with fewer than 10.7 open role-days (1.5 role-weeks) are marked as a small sample and not ranked: below that the pooled rate of the two sides weighs more than a row's own clicks (the weight fitted on their own clicks). All AI training work is one set, read from its first open role-day.

Apply clicks measure interest among visitors to AITraining.jobs, who see roles open in their country and recent, priced roles first. Clicks are never split by platform.

Listing date: the date the 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 none.

The index divides each row's rate by the rate of all roles in this kind of work, so it reads within the kind.

Sample. 207 roles in AI Evaluation & Rating (RLHF) open at the end of 31 Oct 2026, for residents of a fixed set of 20 countries.

A country's count is the roles open worldwide (including roles that state no rule, as on the job board), plus roles whose list names it, plus roles whose exclusion list does not.

The 20 countries are the same in every report of this series: those named most often by the location rules of open AI training roles on 9 Oct 2026, either as the only countries accepted or as excluded.

Median pay is over the roles open to that country that state an hourly rate (at least 3).

A mention can be a requirement or a preference ('a PhD is a plus'): the figure counts both. The patterns are those of the requirements report.

Only some platforms publish full descriptions, so this figure describes their roles, not every platform's.

A kind of work's figure is shown when its described roles outweigh the average of the kinds (5.8 described roles: the weight of every kind's shares around the shares of all described roles, fitted on their own counts).

Buy the data behind this report

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

  • 11,482 roles tracked, each with its history

    Every role on 62 job boards, read since 13 Jul 2026 (every hour since 18 Oct 2026): its pay and place, and the first and last day it was open.

  • 58,632 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

Method and definitions

The public job boards of the AI training platforms this site tracks, read every hour. Apply clicks are made on AITraining.jobs; full descriptions come from the platforms whose boards publish them. 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.

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; this report counts the roles classified as AI Evaluation & Rating (RLHF).
Fixed panel
The platforms already tracked when the weekly series opens. The index follows their open roles, so a platform added later (such as OpenTrain AI and Welo Data in September 2026) never reads as growth.
Index
The panel's average open roles in a week, divided by the same in the base week, times 100; shown beside the same index for all AI training work on the same platforms.
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. A median needs at least 3 removed roles.
HHI
Herfindahl-Hirschman Index: the sum of every platform's squared percentage share of open roles, 0 to 10,000. Under 1,500 unconcentrated, 1,500 to 2,500 moderately, above 2,500 highly concentrated.
Advertised pay
The hourly figure a posting states (the middle of a stated range), counted once per distinct rate as the job board counts it. The median and typical pay are the board's: typical pay runs from the 25th percentile of what roles pay (the middle of each advertised range) to the 90th-percentile advertised ceiling, stated from 3 distinct rates.
Clicks per open role a week
Apply clicks on AITraining.jobs on a specific role, divided by the days the roles were open, times 7.
Demand index
Clicks per open role a week divided by the same rate across every role on the site. Above 1, the roles draw more applicants than the average role.
Listing age
When a role was listed relative to the window's first day: during the window, up to 4 weeks before it, 4 to 12 weeks before or longer. The listing date is the job board's posting date, or else the first day the role appeared in the feed.
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.
Open to a country
A role is open to residents of a country if it is open worldwide, its list names the country, or its exclusion list does not. The 20 countries compared are the same in every report of the series.
Window
Live: the last 28 complete days, in UTC, and the last twelve complete ISO weeks (from the week of 3 Aug 2026 at the earliest) for the weekly series. Edition: one calendar month, in UTC, and its weeks.

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. Clicks are never published by platform.
  • Full descriptions are published by a few platforms only, so the requirements figure describes their roles and appears only when this kind's described roles read on their own against the other kinds' (the weight of every kind's shares around the shares of all described roles, fitted on their own counts).
  • A kind of work with few open roles gives figures that move with a handful of postings: rows on too little data are marked as a small sample.

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.
