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.
The simulation platform for agent self-improvement
Run your agent through thousands of realistic scenarios and get scored feedback in minutes instead of waiting weeks for expert log review.
Create structured experiments and test ideas quickly in an AI laboratory before committing to a change.
Start from a validated metric library of industry benchmarks, customize proven metrics, or build your own to track what matters.
Create, test and track your best-performing prompts in one place, keeping a history and a single source of truth for the team.
