About AI training work

AI training (data labeling, annotation, and human-feedback work) is the human side of building modern AI. Contributors prepare and judge examples that teach models how to respond, reason, and personalize for real users.

This type of work is often remote and flexible, accessible to people without specialized degrees, and lets you directly influence how cutting-edge systems behave.

This is a remote contractor, part-time engagement with an expected duration of 3 to 4 months. OpenTrain AI hires and manages the contract for this project.

• Compare alternative responses and select which gives the better user experience.
