Bug Report
I’m subscribed to the Max plan, but in Claude Code the default model is incorrectly displayed as “Sonnet 4 for daily use.”

Steps to reproduce

Open Claude Code.

Check the model selection menu.

Observe that the default option is set to Sonnet 4 for daily use.

Expected behavior
Since I’m on the Max plan, the default should display as “Opus 4.1 for up to 20% of usage limits, then use Sonnet,” rather than Sonnet 4.
