Sam Altman stated that over 800 million people use ChatGPT weekly, but pressure from rivals has increased.

The CEO of OpenAI, Sam Altman, informed employees that ChatGPT is returning to a monthly growth rate of over 10%, with over 800 million weekly users. In the context of increased competition with rivals such as Google and Anthropic, OpenAI is preparing to launch an updated Chat model. Altman mentioned that the Codex product has grown by 50% in a week, thanks to the launch of the new GPT-5.3-Codex model and an application for Apple users. Additionally, tensions with Anthropic have intensified after the latter launched critical ads during the Super Bowl.

OpenAI will begin testing ads in ChatGPT, which will be clearly labeled and will not influence the generated content. In discussions with investors, Altman highlighted the growth of the user base and the expansion of the enterprise segment, in the context of a funding round that could reach 100 billion dollars, with contributions from Microsoft, Nvidia, and Amazon.
