Background & analysis
On October 20, 2026, OpenAI publicly confirmed a bug that applied the wrong usage limits to approximately 40,000 Codex accounts. A guide last updated on November 3, 2026 describes the episode and draws a line between this confirmed misconfiguration and the real caps attached to each plan, noting that the real limits carry no fixed number of messages per day. In practice, a usage meter draining at a speed that makes no sense does not necessarily mean a user hit a genuine cap; it may indicate that the confirmed bug was involved. The same guide explains how to check a Codex account's actual usage and how to determine whether the error being seen belongs to this bug rather than to normal throttling. The latest verifiable information available in the material is that November 3, 2026 guide, and it provides no further detail on what happened to affected accounts after the confirmation.

Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
