How this pay compares
The title points to writing prompts, problems and answers: writing questions, test tasks, rubrics or model answers for a model to learn from. What each kind of AI training work pays
At $100/hr, this role pays more than 76% of the 207 open engineering roles with a listed pay range, above the median of $80.
Among platforms with 10 or more priced engineering roles, Mercor has the highest median ($88/hr across 35 roles) and micro1 the lowest ($60/hr across 28).
OpenTrain AI roles that closed since late October stayed listed a median of 31 days (122 roles). OpenTrain AI posted this one 6 days ago.
Computed from 2,746 open roles we track across Mercor, micro1, Handshake AI, Alignerr, Appen and OpenTrain AI, refreshed daily. Midpoints of listed ranges; “up to” ceilings are left out of medians.
