About AI Training Work

AI training (also called data labeling or human feedback) is the human foundation for modern machine learning. People prepare, review, and rate examples that models learn from—tasks that range from simple classification to nuanced quality evaluation.

This work is often highly flexible and remote-friendly: many contributors choose hours that fit their schedules, apply language skills or domain experience, and directly influence model behavior and safety.

The Role

OpenTrain is hiring detail-oriented freelancers to review and annotate text data used to train and evaluate AI models. You will classify content, rate responses, validate labels, and flag edge cases or guideline issues.

This is a contractor, part-time opportunity with a typical minimum commitment of 20+ hours per week. Work is fully remote and requires independent time management to meet productivity and quality targets.
