What
Some organisations route Claude Code through a gateway, a server in between that handles sign-in (here, sign-in through OIDC, a common single sign-on standard) and passes requests on. Claude Code's gateway diagnostics now warn when such a gateway offers model IDs that Claude Code does not recognise.
The warning says to list those models in modelPicker.options, the setting that controls which models the /model picker shows, and gives an example that uses behavesAs to say which known model each one acts like.
Why
Admins running their own model gateway get a pointer to how to make unfamiliar models show up and behave properly, instead of being left with models Claude Code does not know what to do with.
