How they use Nebius AI Cloud
Toloka runs the training stages of its enterprise agent fine-tuning service on Nebius compute. The service builds expert-corrected workflow data, reinforcement-learning environments and held-out evaluations, then post-trains small open models for narrow tasks. Training starts with supervised fine-tuning, followed by efficiency work and reinforcement learning where evaluation justifies it.
Toloka also offers the resulting model weights hosted on Nebius and a drop-in, OpenAI-compatible endpoint. Customers own the weights. Its service page describes collecting logs and trajectories to improve checkpoints within the customer's data boundary.
Separately, Toloka announced plans to integrate Tendem's human-expert capabilities into the Nebius ecosystem. That announcement described MCP integration as early access and deeper Nebius integration as planned. Nebius also lists Toloka as an ecosystem partner.
