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.
All-in-one content moderation API for images and video
Screen photos, videos and live streams for unwanted content through a single automated API.
Detect nudity, weapons, alcohol, narcotics, offensive gestures and hate symbols without building your own models.
Extract text from images, verify PPE compliance (face, hand and head covers) and run real-time facial similarity matching.
Minimal-code integration with ready-made SDKs and documentation so teams can ship quickly.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
