Toloka
Data major with managed, harness-agnostic RL gyms
Data majorTool useComputer useApp replicasCoding and SWE
Toloka publishes one of the most detailed RL-gym menus: MCP replicas of enterprise tools with realistic schemas and permission models, containerized browser and web-app mockups, simulated multi-user companies, and Tau-style gyms calibrated to about a 50% pass rate. Delivery is managed end to end, with versioned environments and deterministic resets, and works with Toloka’s harness or yours.
Best for: Managed gyms that plug into your own training harness
