On September 25, a long-term ChatGPT Pro 20x subscriber posted on OpenAI's own community forum that hard usage limits had appeared on the plan without advance notice. The subscriber said the Pro model option became unavailable, with ChatGPT showing a "Limit reached. Try again after 4:59 PM tomorrow" message.

The post says the documentation now refers to hard daily and weekly caps, with no visible usage meter before the limit hit and no email or in-product notice to existing subscribers. At launch, ChatGPT Pro was sold at $200 a month with "unlimited usage," the poster notes, and describes the caps as a product regression rather than a plan change. OpenAI has not publicly responded to the report.
