OpenAI doubles usage limits on Pro plans as competition with Anthropic heats up

OpenAI has doubled usage limits for Pro plans, raising quotas from 100 to 500 messages while canceling a previously planned reduction. This adjustment follows user feedback and anticipates the upcoming IPO of rival Anthropic. The update also leverages the improved efficiency of the Terra and Sol models to increase total system capacity. This shift reflects a broader strategy to retain subscribers amidst intensifying competition in the AI sector.
