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.
Multilingual AI data, model alignment, and sovereign AI systems for enterprises and labs
Access an expanding catalog of text, parallel corpora, speech, audio, image, video, multimodal, and evaluation datasets, or commission collections tailored to specific languages, domains, and recording conditions.
Labeling guidelines, metadata enrichment, expert review, preference data, and human-validated evaluation sets for comparing models across languages, domains, and tasks.
Adaptive machine translation that learns from translation memories and glossaries, with machine translation quality estimation to score output and prioritize human review.
Small language model customization, retrieval and knowledge grounding, and deployment on private cloud, on-premises, or air-gapped infrastructure for sensitive data.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
