closed this as the below was the fix
Run in PowerShell:
[Environment]::SetEnvironmentVariable("CODEX_CLI_PATH", $null, "User")
Remove-Item Env:CODEX_CLI_PATH -ErrorAction SilentlyContinue
Then fully close and reopen the ChatGPT/Codex app. This fixed the missing GPT‑5.6 models for me without resetting or reinstalling the app.
