Overview
Mindrift is a platform operated by Toloka that recruits subject-matter experts to generate and evaluate the training data used to improve large language models. Contributors apply in their own professional field, from software engineering and medicine to law and linguistics, and complete paid projects such as writing reference answers, ranking model outputs, red-teaming responses and building reasoning traces for specific domains. The work is remote and project-based, which is why the platform posts a very large volume of freelance vacancies across many languages and specialisations at once.
