*Given the fact that in just a few days Mythos was able to discover
thousands of previously unknown zero-day vulnerabilities to our critical
software infrastructure, some of which have existed for decades, and given
the fact that it seems to know a great deal about germ warfare, it sure
sounds like more than a marketing gimmick to me. And if it is a marketing
gimmick it isn't working because it's making thousands of Anthropic's
customers who have not been given full access to Mythos furious. *
