Toloka review: an AI training data provider for agents, with a self-service option
Answer in brief: Toloka is our #10 AI training data provider for labs. It supplies training data for AI agents and LLMs: context-rich RL environments, agent training datasets, RLHF and preference data, instruction tuning, coding data, evaluation and red teaming. Toloka says it has 200,000+ experts across 90+ domains. Uniquely in this tier, it pairs managed projects with a self-service platform that builds your pipeline from a plain-language goal and checks every output with LLM-based QA. Homepage quotes are anonymous, and managed pricing is not public.
Bottom line: For agent builders who want realistic environments, or who want to launch a pipeline themselves today, Toloka is one of the most flexible choices here.

Self-service that builds the pipeline for you
On Toloka's platform you describe your data goal and answer a few questions about workforce split, consent and storage. An agent then builds a multi-stage pipeline covering task UI, guidelines, quality criteria and pricing. You calibrate the QA on a few tasks yourself before scaling. Toloka reports that its LLM QA catches failures with 89.1% accuracy. Experts are matched automatically from domain specialists, general annotators or a global crowd.
