OpenTrain AI

OpenTrain AI runs a talent marketplace that connects AI companies with vetted trainers and data labelers. The work it supports spans reinforcement learning from human feedback (RLHF), red teaming, model evaluation, data annotation and other human-in-the-loop tasks. For freelancers, the company offers a profile through which they can find AI training and data-labelling opportunities across multiple platforms; the network includes specialists from different professional fields, speaking different languages and based in different countries.

For employers, OpenTrain AI offers two models. Self-service hiring allows clients to post roles, review matched candidates, manage projects and pay contributors through OpenTrain, or to bring vetted talent into their existing tools. Managed programs cover recruitment, onboarding, quality assurance and performance management for client AI training projects. Vetting can include live interviews and proctored testing.

The company operates in the AI/ML, artificial intelligence training and data-labelling sectors. Its website is www.opentrain.ai.
