Goldman Sachs has stopped its Hong Kong bankers from using the artificial intelligence models developed by Anthropic. This move is part of the growing tension between the United States and China over high-end technology and finance. While major American AI tools like ChatGPT and Claude are banned in mainland China, Hong Kong has traditionally enjoyed more freedom. The bank's decision to block Claude could challenge Hong Kong's efforts to become a global financial hub. The ban is also significant due to Anthropic's new "Mythos" AI model, which could potentially crack modern security systems, raising concerns about its potential threat to the entire global financial network.
