Unclear Which model is no longer listed for Vertex is not known.
What
Claude Code ships with a built-in model catalog and settings vocabulary that list the cloud providers where each model is offered. Several entries changed:
One model entry's offered_on list went from ["bedrock", "vertex"] to ["bedrock"].
mantle no longer appears among the providers in the settings vocabulary or in the bundled model-catalog schema.
The catalog version moved from 3134 to 3190.
In a sandbox setting description, the example XPC service name is now spelled com.apple.CoreSimulator.*. A sandbox is the restricted environment some commands run in.
Why
These lists shape the provider options Claude sees when helping with configuration. If you use Vertex, that one model is no longer listed as offered there, and mantle is no longer suggested as a provider.
