[Large Numbers of OpenAI Users Switch to Anthropic, the Latter Tops U.S. App Download Charts] According to Golden Finance, after the Trump administration discontinued the use of Anthropic's artificial intelligence products, OpenAI quickly reached an agreement with the U.S. Department of Defense to deploy OpenAI models within the department's classified network. The incident triggered backlash from OpenAI users, leading to protests and a boycott movement. Within a short period, 700,000 users canceled subscriptions or even uninstalled ChatGPT, switching to Anthropic's Claude instead. With significant user support, Anthropic's Claude soared to the top of the free download charts in the U.S. app stores, while OpenAI's ChatGPT and Google's Gemini ranked second and third, respectively. Claude had previously experienced an increase in failure rates, which may be related to the sharp rise in traffic.
