OpenAI has confirmed that ChatGPT operates "with a high number of errors." Both ChatGPT and the company's application programming interface (API) experienced a "serious" outage, while the Sora video generator faced a "partial" failure. The reasons for these issues are currently unknown.
ChatGPT gained popularity in late November 2022, amassing its first million users within a week. As of the end of summer 2024, the number of its active users has surpassed 200 million.
