Summary
According to an X post from Brad Lightcap, chief operating officer of OpenAI, the artificial intelligence (AI) company has surpassed 400 million weekly active users, marking a significant milestone given the company’s growing reach across both consumer and enterprise markets.
Despite competition from Elon Musk’s xAI and China’s DeepSeek, both of which have launched high-performing models, OpenAI has seen its use in businesses double to more than two million enterprise users since September 2024, seeing particular success in the business sector.
OpenAI also plans to launch GPT-4.5 and GPT-5, with the latter merging the company’s GPT and o-series models and the former being offered for free to users.
The next leap in AI is critical to maintaining OpenAI’s lead in the face of intensifying competition. Given the rapidly expanding user base of AI tools in business, GPT-5’s launch will likely be an important test of OpenAI’s ability to maintain its lead as the dominant provider of both consumer and enterprise AI applications.
