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.
One real-time ledger for metering, credits, pricing and entitlements
Every billable event is counted once and every limit is applied in real time, by company, user or agent, so usage and access never drift apart.
Sell usage as credits with configurable burn rates, rollover percentages, auto top-up thresholds and deadlines on promotional grants.
Define plans, add-ons, trials and feature gates as data, then version a change, preview how it looks to customers, and roll it out without deploying code.
Model seats, pay-as-you-go, tiered overage, pay-in-advance commitments, hard and soft limits, or hybrids in the same engine.
