Editorial summaries

Fourier GR-2

Fourier's GR-2 (from Fourier Intelligence, Shanghai) is a second-generation bipedal research humanoid (GRx generation 2, 2024). DEPLOY records it at research maturity with no verified deployments: it is a development and demonstration platform, not a commercial-deployment-at-scale product. As a research platform it has no consumer price. Cap-flag: most Chinese-humanoid commercial-deployment framing in this cohort, GR-2 included, is aspirational demonstration; the verification posture is demonstration, not verified autonomous deployment.

Walker S2

The Walker S2 is UBTech's enterprise humanoid, with verified factory pilots at BYD, FAW-Volkswagen, Foxconn, Geely, NIO, and Zeekr in China. UBTech is publicly traded on the Hong Kong exchange. The Walker S2 is not sold to consumers; the editorial position is honest-absence on consumer pricing.
