Mythos isn’t released yet.

Anthropic noticed the trend of AI vulnerability scanning and started advertising Mythos, which is unreleased, as being very good at it.

Then they donated very large token budgets for using Mythos privately to several teams. Those teams used the free token spend for security research (that was the deal) and anything they found got attributed to Mythos, not the token budget.

Mythos looks like a good incremental model but the PR team has done a great job of associating themselves with the current trend. So much so that comments like yours already associated vulnerabilities found with this model which isn’t even available yet
