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.
AI visual inspection and enterprise-grade scanning for industry
Computer-vision models run on production lines to detect defects, verify labels, count objects and check PPE for workplace safety, in real time rather than in spot audits.
Integrate high-performance barcode, QR and serial code reading into any smart device so staff can capture enterprise-grade data without dedicated hardware.
Read VIN numbers, tire sidewall DOT/TIN codes, component numbers and handwritten codes directly from a phone or smart device.
Capture customer identity documents such as passports, ID cards and driver's licences to speed up KYC, patient registration and check-in workflows.
