What version of Codex is running?

3eba86a

Which model were you using?

_No response_

What platform is your computer?

Darwin 23.6.0 arm64 arm

What steps can reproduce the bug?

1. Install nix and enable experimental features nix-command and flakes.
2. Run: nix build github:openai/codex

What is the expected behavior?

The flake is built in the nix store and symlinked under result in the current directory.

What do you see instead?

❯ nix build github:openai/codex
