Given its capabilities, the US-based artificial intelligence company has decided to scale back its public-wide release. <\/p>\n<p>If misused, Mythos could pose a serious threat to economies, public safety, and national security, the Anthropic CEO warned.<\/p>\n<p>In recent days, heads of major financial institutions and the banking system have expressed concerns over the risks posed by AI models. They are also urging people to join the list of early testers to protect their own systems. <\/p>\n<p>Additionally, recent reports of unauthorized access highlight security flaws and highlight the challenges Anthropic faces in completely preventing access to its most powerful models beyond approved partners. <\/p>\n<\/p><\/div>\n<p><script type=\"text\/javascript\">\n      \/*var images =
