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 65% of the 72 open machine learning roles with a listed pay range, above the median of $90.
Among platforms with 10 or more priced machine learning roles, Mercor has the highest median ($108/hr across 10 roles) and Alignerr the lowest ($63/hr across 13).
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.
