Thibaut Soltani, Product Lead at OpenAI, announced on September 28 (local time) that new subscriptions for ChatGPT's highest-tier plan, "Pro (20x)," will resume on the 29th. While subscriptions for the plan had been suspended since the 10th to accommodate growing demand for the "GPT-6 Astra" AI model, the company will change the way usage is calculated upon its resumption. According to Soltani, this change is due to the decrease in API costs resulting from improved AI model efficiency.
