OpenAI Tests "Luna Reserve" Feature for Codex Usage Limits

heypearlai · x · 2026-08-28

Users spotted a new "Luna Reserve" feature in OpenAI Codex. Instead of a hard lockout after hitting the advanced model limit, the system downgrades users to a separate reserve pool with its own meter. This appears to be a middle ground between unlimited overruns and strict cutoffs, aiming to prevent abuse while avoiding mid-task interruptions. No official word yet; it may be a slow rollout.
