For AI issues: which model did you use?

GPT-5.1-Codex-Max all models

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi everyone, the Codex Max model is new and likely under heavier load which also impacts the previously existing regular Codex. The issue is mostly temporary and we are able to access it again.
