Our LLM data services cover RLHF annotation, RM annotation, SFT annotation, Agent annotation, multi‑turn text authoring, multimodal data annotation, LLM evaluation and LLM fine‑tuning. We maintain a dedicated in‑house LLM annotation team, where 30% of staff hold degrees from top‑tier Chinese universities (Project 985/211), enabling us to deliver efficient, high‑quality services for LLM vendors.

Our in‑house VisuLab annotation platform enables loading of hundreds‑of‑millions‑scale point clouds. We offer full‑scene 2D/3D/4D annotation: vehicle‑pedestrian detection, continuous‑frame labeling, point cloud semantic segmentation, object tracking, 2D‑3D fusion, BEV, 4D annotation (lane lines, traffic lights) and map logical layers, covering all in‑cabin & out‑of‑cabin annotation needs. With Grade‑B surveying and mapping qualification, we conduct road, in‑cabin and out‑of‑cabin data collection, delivering high‑quality multi‑scene road data for autonomous‑driving companies.

We provide multimodal training‑data solutions for embodied‑intelligence clients. Backed by 6 domestic self‑run bases and thousands of full‑time specialists, we support UMI, ego‑centric and motion‑capture data collection. Our proprietary EmbodiLab platform delivers pose‑angle‑vision‑based annotation and closed‑loop iteration to boost robots’ reinforcement learning and physical‑interaction performance.
