Environment

• Platform (select one):
• [X] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.61 (Claude Code)
• Operating System: Windows 11
• Terminal: Git Bash ("C:/Program Files/Git/bin/bash.exe" -i -l)

Bug Description

When launching Claude Code in Windows Git Bash and logging in, the system incorrectly identifies an account with the Max plan as a Pro account instead.

Steps to Reproduce

1. Perform the installation, follow the defaults for theme selection and login.

Expected Behavior

<!-- What you expected to happen -->
Login is complete, and the Opus model is now available.

Actual Behavior

<!-- What actually happened -->
The login category differs from the original account status, making the opus model unavailable.

> /model opus
  ⎿  Invalid model. Claude Pro users are not currently able to use Opus 4 in Claude Code. The current model is now
     Sonnet 4.
