ChatGPT Pro account is shown as Plus in Codex CLI/TUI

Summary

My ChatGPT account is a Pro account, but Codex CLI/TUI is showing the account as Plus. This makes it unclear whether Codex is using the correct subscription entitlement for long-running CLI sessions.

Environment

• Codex CLI: codex-cli 0.142.5
• Platform: Linux x86_64 on an HPC login node
• OS reported by codex doctor: Red Hat Enterprise Linux 8.8.0
• Auth mode reported by codex doctor: chatgpt
• Stored API key: false
• Stored ChatGPT tokens: true
• Model shown in TUI: gpt-5.5 xhigh

What I checked

I verified two active Codex CLI sessions using different CODEX_HOME locations:

Session A:
  CODEX_HOME=/scratch/.../algo_work
  codex login status: Logged in using ChatGPT

Session B:
  CODEX_HOME unset, so default ~/.codex is used
  codex login status: Logged in using ChatGPT

The two auth.json files have the same SHA256 checksum, so both sessions are using the same stored ChatGPT login token. I did not inspect or print token contents.

codex doctor reports auth is configured, but it does not expose the subscription tier. The TUI/account banner is what appears to show Plus even though the ChatGPT account is Pro.

Expected behavior

If the authenticated ChatGPT account is Pro, Codex should either:

1. show Pro in the CLI/TUI account/subscription display, or
2. provide a clear diagnostic if the CLI is intentionally using a different entitlement than the web ChatGPT subscription.

Actual behavior

The account appears as Plus in Codex CLI/TUI, despite the account being Pro.

Reproduction steps

export CODEX_HOME=/scratch/.../codex_home
codex login --device-auth
# Complete auth in browser using a ChatGPT Pro account
codex login status
codex doctor
codex

Then inspect the account/subscription indicator in the TUI.

Notes

• No OPENAI_API_KEY is set in the active Codex process environment.
• The sessions are using ChatGPT login token auth, not Platform/API-key auth.
• A useful improvement would be for codex login status or codex doctor to print a sanitized account tier/plan field so users can verify whether Pro/Plus/Team entitlements are being applied correctly.
