Toloka Platform is a self-service data labeling and human-in-the-loop (HITL) infrastructure for AI teams building and evaluating large language models.
Built on the same foundation used by Frontier AI Labs and Big Tech like Microsoft and Amazon, Toloka Platform gives AI researchers, ML engineers, and technical teams immediate access to high-precision human feedback workflows—without sales calls, procurement delays, or enterprise minimums.
Core Capabilities:
AI-Assisted Pipeline Design
Describe your annotation goal in plain language ("I need to rank LLM outputs for safety"), and the built-in AI Assistant generates the complete workflow: annotator instructions, task interface, quality control logic (gold sets, overlap, consensus thresholds), and skill-based routing. What traditionally takes data ops teams days to configure now launches in minutes.
Access to Expert Annotators
Route tasks to a vetted workforce of 10,000+ contributors, including domain specialists in STEM, medicine, engineering, and technical fields, as well as PhD-level annotators for complex evaluation work. Continuous performance tracking ensures data quality at scale.
Production-Grade Quality Controls
Every annotation project includes built-in validation: 100% LLM-based QA coverage, customizable gold standard tests based on your own examples, inter-annotator agreement scoring, and real-time quality dashboards. RLHF and safety evals require ground truth you can trust to train on—Toloka Platform is designed for that precision.
Fully Self-Service Workflow
Sign up, upload unlabeled data (model outputs, prompts, or raw datasets), configure quality thresholds in the browser, and launch to annotators immediately. Results export as JSON. No API integration required. No vendor onboarding process. Pay per completed annotation with transparent, upfront pricing.
Who Uses Toloka Platform:
Teams working on reinforcement learning from human feedback (RLHF), constitutional AI, red-teaming evaluations, prompt engineering, model safety testing, and dataset generation for fine-tuning. Built for organizations that iterate on human feedback as rapidly as they iterate on code.
Toloka Platform eliminates the data tax—the operational overhead that typically delays model evaluation and alignment work. From 10-task pilots to 10,000-task production runs, the platform scales with your needs without requiring contract negotiations or dedicated data ops headcount.
