ChatGPT's weekly user base has doubled in less than a year

OpenAI reports that more than 200 million people use ChatGPT each week, as first reported by Axios. OpenAI spokesperson Taya Christianson confirmed the figure , which is now double the 100 million weekly active users OpenAI reported last November. Additionally, Christianson said 92% of Fortune 500 companies use OpenAI's products, and usage of the API has doubled since the release of the company's cheaper, smarter model, GPT-4o Mini.

Since ChatGPT's release in late 2022, Google, Microsoft and Meta have also released their own AI chat interfaces. Today, Meta CEO Mark Zuckerberg revealed that the company’s AI assistant has reached over 400 million monthly active users and 185 million weekly active users  despite not rolling out in the UK, Brazil, or EU yet.

Earlier today, the US AI Safety Institute also announced that OpenAI and Anthropic have agreed to let the government evaluate major AI models before being launched to the public. Reports are also circulating that Apple and Nvidia could be next investors in OpenAI.
