What version of Codex CLI is running?
0.130
What subscription do you have?
Pro
Which model were you using?
GPT-5.5 Medium
What platform is your computer?
Windows 11
What terminal emulator and version are you using (if applicable)?
Powershell
What issue are you seeing?
I used /goal on GPT 5.5 Medium, but noticed the speed was insanely high so I was suspicious.
After checking my usage page on chatgpt.com/codex/settings/usage I noticed my 5.3 spark usage decreasing, not my regular allowance.
I ran /status in the CLI and it showed GPT 5.5 Medium.
What steps can reproduce the bug?

What is the expected behavior?
GPT 5.5 Medium being used, ie the model I actually selected.

Thanks for the bug report. This turns out to be the same underlying problem as https://github.com/openai/codex/issues/22090. I'm exploring ways to fix both.
