Take Mythos seriously, but don’t panic. Here are the facts: • Mythos is a real threat. And it can really help with finding bugs (as @mozilla’s new report documents well). • It’s not unique; similar vulnerabilities can in fact be found by other systems (see @CNBC report below). • The threat is biggest to weak, poorly protected systems, per the UK @AISecurityInst’s careful study. (Mozilla’s report is also consistent with this.) 8 year old aren’t going to accidentally take down power grids. • Mythos is NOT godlike AI or a quantum leap. It’s just an on-trend progression. As @ramez put it, “on @EpochAIResearch 's public ECI [benhmarks] .. it's clear that… Mythos is pretty much on trend, just slightly above GPT 5.4” Global banks, tech giants and governments were sent scrambling last month to contain the risks posed by Mythos, the Anthropic model said to be so powerful that it has found thousands of previously unknown vulnerabilities in the world’s software infrastructure. There’s just one pr…
