Founding Story

ChatGPT was launched by OpenAI on November 30, 2022. OpenAI was founded in 2015 as a non-profit AI research lab by Sam Altman, Elon Musk, Greg Brockman, and others, with a mission to ensure AGI benefits all of humanity. ChatGPT reached 1 million users within 5 days of launch and 100 million monthly active users in 2 months, making it the fastest-growing consumer application in history. In 2023, Microsoft invested $10 billion, integrating OpenAI technology into Bing and Microsoft 365, sparking the modern AI revolution.

FAQ

Yes, if you are in a geo-blocked region (like mainland China), you must use a VPN to register and use the service.
Yes, the basic version using GPT-4o mini is completely free. The Plus plan costs $20/month.
By default, OpenAI uses your conversations to train its models. You can disable chat history in Settings to protect your privacy, and this also prevents that data from being used for training.
