OpenAI has restored five-hour limits for Codex and Work usage by ChatGPT Plus users, according to a Techmeme summary of Marcus Mendes at 9to5Mac. The report says the restriction returned after several weeks without it. OpenAI’s stated reason, according to the same summary, was to smooth load on its compute. The available sourcing is narrow: this cluster contains only one reputable aggregation item, and the underlying summary is brief. It does not provide the exact mechanics of the five-hour limits, whether the limits vary by usage type, or whether other ChatGPT plans are affected. For now, the clean read is that OpenAI is again using usage caps on some paid ChatGPT features as a capacity-management tool. The group named in the Techmeme item is ChatGPT Plus users, and the named features are Codex and Work. Who benefits: OpenAI may benefit if the restored limits help distribute compute demand more predictably across ChatGPT Plus usage. Who's exposed: ChatGPT Plus users of Codex and Work are the users identified in the Techmeme item as subject to the restored five-hour limits.
