@justinyoo can you take a quick look at this? gpt-5-mini is a model listed on the GitHub model marketplace but this change is noting that "it doesn't exist".

sorry for the sassy commit message, I thought I was committing to my repo when I wrote this, but yeah I wasn't able to get this to work with gpt-5-mini

Hmmmm interesting. Have you tried it with GitHub Codespaces or devcontainer?

I use both Windows and MacOS, and this works on both machines. It also works on GH codespace instance using gpt-5-mini.

I'll close this PR.
