OpenAI has once again opened its ChatGPT Pro subscription to new users. The service, which costs $200 per month, has undergone changes in how usage is measured. The new plan offers about half the API consumption capacity of the previous version. However, users will no longer face a strict five-hour limit on their Pro subscriptions, giving them more flexibility in how they use their weekly allowance. OpenAI claims that the reduced usage is balanced by improvements in model efficiency and lower API costs for its latest models, GPT-6 Sol and GPT-6 Luna, which have seen a 50% drop in pricing compared to earlier versions. In addition to the Pro 200 plan, OpenAI has launched a new tier called Pro 500, priced at $500 per month. This plan offers 25 times the usage capacity of the Plus subscription and gives access to the GPT-6 Astra Ultrafast mode, a specialized version of the model designed for speed. The Pro 200 plan, however, has had its usage capacity for Work and Codex reduced from 20 times to 10 times that of the Plus subscription. Current Pro 200 users will continue to have their original usage limits until October 29, 2026, as long as their subscriptions remain active. Thibault Sottiaux, head of Codex and ChatGPT Work at OpenAI, stated that the changes are meant to better align subscription benefits with actual API pricing, avoiding situations where API prices are artificially inflated to make subscriptions seem more valuable. OpenAI also plans to introduce new features and services to Pro subscriptions starting September 30, which will not consume usage credits. However, the details of these new features have not been revealed yet. OpenAI’s recent changes come as the company faces financial difficulties. Projections suggest it could experience a cash flow loss of nearly $280 billion by the end of 2030, with its $122 billion funding round expected to run out by 2028. Despite this, the company expects to generate about $840 billion in total revenue by 2030. The restructuring of its subscription plans reflects a broader effort to adapt to a market where token prices are falling due to greater competition and lower production costs, especially from Chinese open-weight models.
