An ai model created by Anthropic was announced as a closed preview on April 7,
2026 for critical security research and evaluation with its close partners with
critical software such as operating systems and browsers.  Anthropic claims
that mythos is able to reason through so much more context that any model ever
before.  This enables it to find bugs that are 25 years old in the BSD,
considered one of the most secure operating systems we have.  Once it finds
these zero day bugs never discovered before its able to use them together in
malicious ways never expected.  In ways the world is not ready for.  At the
time of writing these are claims without proof.  It remains scary to know the
potential this has and that there is only a few companies with this potential
that will gatekeep who gets access.
