Summary

The article discusses the media frenzy around Anthropic's AI model Mythos in April 2026, which was reported to be exceptionally skilled at finding security flaws in source code. Anthropic decided not to release the model publicly, instead rolling it out selectively to certain companies to allow them to fix critical vulnerabilities first. The article appears to be skeptical or critical of the media hype surrounding this event, framing it as overblown. The specific mention of finding a curl vulnerability (singular) seems to undercut the dramatic narrative.
