Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
Test and observe game bots in safe, simulated environments
Emulate the game client environment so bots can run without touching live servers, accounts or economies.
Put a bot into challenging, edge-case situations in seconds rather than waiting for them to occur naturally in a live game.
Judge performance by observing what the bot does, without reading or tracing its source code.
Evaluate whether a bot performs consistently and avoids unsafe, unintended or destructive actions.
