What we produce
Structured production for large-model training, evaluation, and scenario-specific deployment — across every modality your model needs.
Mandarin, dialect, multi-speaker, and conversational data — transcribed, segmented, and speaker-labeled for speech and multimodal models.
Collection, cleaning, frame extraction, object and event labeling, and scene tagging for training and evaluation.
Instruction data, preference data, red-teaming, evaluation and benchmarking, and agentic trajectory data.
Exclusive access
Through a membership organization in China, we hold exclusive broadcasting and distribution rights to hundreds of hours of Chinese dialect audio and video — sourced directly from broadcast, news, and social media. It's coverage most data vendors simply can't replicate.
