We are not another annotation mill. We are the trust layer of intelligence — expert judgment and the physical world, written as data that can be trained, audited, and bought.
01 / 03
The next decade of AI will not be won by the largest model. It will be won by the most trustworthy training substrate.
Scale AI turned data into an industrial commodity in the West. Lumesage turns data into a scientific instrument: provenance, calibration, uncertainty, expert signature.
Langhui AI trains the mind of the model. TOBI trains the body of the robot. The group sits above both — narrative, standard, and value.
Two poles
01
Built to stand beside Scale AI
Expert-grade training data for frontier models: SFT, RLHF, multimodal, medical, legal, STEM. Not crowdsourcing. An expert closed loop.
02
Physical AI data
Production E2 / E6 / E8 ego capture rigs and 700,000 hours of tradeable first-person data for VLA, world models, and humanoids.

Holding structure
Beijing Langhui is the parent. Changsha Langhui operates langhuiai.com for foundation models. TOBI operates tobi.cn for ego hardware and embodied datasets. Lumesage is the global standard that binds them.
Group →Invitation
Funds, foundation-model labs, and robot companies enter the same door. What we offer is not a rate card. It is a due-diligence-ready data balance sheet.
