Every week: what changed in the market for AI training work in our data (new platforms and programs, pay, open roles by kind of work, what the AI labs are hiring for) and what was reported about the platforms, each item with its source.
On the 62 platforms we read the same way all week, open AI training roles fell 0.7%, from 4,406 at the start of 2 Nov to 4,376 at the end of 8 Nov 2026, as 411 removals outran 381 new listings. Law, medicine and finance roles grew 2.0% to 1,610, and agentic tasks and RL environments 13.2%, from 129 to 146, while math and STEM roles fell 7.4% and multilingual work 4.6%. The board as a whole went from 4,413 to 4,394 open roles on 62 platforms.
On the 56 platforms we read the same way all week, open AI training roles fell 2.1%, from 4,419 at the start of 26 Oct to 4,324 at the end of 1 Nov 2026, as 534 removals outran 447 new listings. Law, medicine and finance roles fell 5.3% and AI rating roles 14.4%, while agentic tasks and RL environments grew from 84 to 124. The board as a whole went from 4,381 to 4,374 open roles on 62 platforms.
On the 36 platforms we read the same way all week, open AI training roles fell 5.6%, from 4,179 at the start of 19 Oct to 3,947 at the end of 25 Oct 2026, as 474 removals outran 289 new listings. The board as a whole went from 4,397 to 4,336 open roles on 56 platforms, and that total is how we read the market, not the market: 20 platforms' own job boards were read for the first time, while Mindrift's board dropped 220 roles in a single day.
On the 12 platforms we read the same way all week, open AI training roles ended exactly where they began: 1,552 on 10 Oct and 1,552 at the end of 16 Oct 2026, as 140 new listings replaced 140 removals. The board as a whole grew from 2,547 to 3,635 open roles, but almost all of that is how we read it, not the market: 12 platforms' own job boards were read for the first time, and the copies of other platforms' roles that OpenTrain AI re-lists were dropped.
