Urges Codex users to immediately enable Max reasoning effort in their settings, as it is turned off by default.
With Max reasoning enabled, the Luna model performs comparably to Sol Medium or Opus 5 Medium, but at only 1/6th of the cost, offering a highly cost-effective optimization for coding workflows.
