OpenAI reopens the $200 Pro plan, same price but API equivalent usage cut in half OpenAI announced the reopening of the $200/month Pro plan but changed the usage calculation method. OpenAI employee Tibo Sottiaux admitted that under the new algorithm, the equivalent API usage is about half of the previous version, meaning the price remains the same, but the actual usage has been reduced. The specific new usage limits have not yet been disclosed. Tibo explained that this week, the API prices for GPT-6 Sol and Luna have dropped by about 50%. With improved model efficiency, theoretically, less usage should still accomplish a similar workload. He also promised not to reintroduce the previous 5-hour limit. However, this claim currently lacks comparative data between the old and new plans. Previously, users had reported abnormal consumption of the Pro 20x usage, such as a single task taking 5.2 hours and consuming approximately 2.4 weeks' worth of usage.
