What
When setting a default model with /model, Claude Code now updates its local state optimistically as soon as the save request is sent, in parallel with waiting for the server to confirm the change, rather than waiting for confirmation before updating what's shown locally.
Why
This makes the model picker feel more responsive when switching your default model, since the interface updates immediately instead of waiting on a round trip to the server.
