These providers haven't been health-probed for this model yet. The router still routes around upstreams that fail live requests — uptime fills in once probe history accrues.

About

GLM 5.3 Prime is the top reasoning tier of Z.ai's GLM 5.3 line, above the Flash and FlashX cuts, with a 1M-token context window. It sits alongside z-ai/glm-5.3 and z-ai/glm-5.3-flash as a separately priced official variant rather than a packaging of them, so it keeps its own listing row.
