Anthropic has operated Mythos Preview and Mythos-class models internally for three months as part of Project Glasswing amid insufficient safeguards for public release
Plans include work with US and allied governments after safeguards improve.
Update on Mythos and Project Glasswing: 'Next, we will work with critical partners—including US and allied governments—to expand Project Glasswing to additional partners. And in the near future, once we’ve developed the far stronger safeguards we need, we look forward to making Mythos-class models available through a general release.'

Last month we launched Project Glasswing, our collaborative AI cybersecurity initiative. Since then, we and our partners have found more than ten thousand high- or critical-severity vulnerabilities in essential software.
'For the last few months, Anthropic has used Mythos Preview to scan more than 1,000 open-source projects, which collectively underpin much of the internet—and much of our own infrastructure.
So far, Mythos Preview has found what it estimates are 6,202 high- or critical-severity vulnerabilities in these projects (out of 23,019 in total, including those it estimates as medium- or low-severity).'

doomers are going to love this sentence
btw it's been 3 months since claude mythos was deployed internally, meaning that time-horizons have almost doubled again
