Grok, an AI chatbot developed by xAI, has seen its usage surge following the release of its latest model, Grok 3. According to data from Sensor Tower, a market intelligence firm, mobile app downloads of Grok increased more than 10 times globally and in the U.S. during the week of Grok 3's release. Daily active users in the U.S. soared over 260%, while global daily active users climbed 5 times week-over-week. The launch of Grok 3, which powers the Grok chatbot apps for mobile and the web, as well as the Grok experience on the social network X, is credited for the increase. The expansion of the Grok app to several new markets in Europe, Latin America, and Southeast Asia also contributed to the global growth. According to Similarweb, a digital intelligence platform, U.S. daily visits to Grok.com increased from around 189,000 to more than 900,000 following Grok 3's release, while worldwide daily visits grew from 627,000 to 4.5 million. Despite the growth, recent controversies have emerged. Grok 3 briefly censored certain unflattering mentions of President Donald Trump and Elon Musk, attributed to a rogue employee. Additionally, users discovered that Grok 3 would consistently state that President Trump and Musk deserve the death penalty, an issue that was quickly patched by xAI. OpenAI's ChatGPT, a competitor, has grown to 400 million weekly active users.
