It’s been only two days since the bombshell news about Claude Mythos broke, and Anthropic can’t wait any longer!
Today, some developers shared screenshots that shocked the entire internet —
The internal testing of Claude Mythos 5.0 Beta has begun, and it has appeared in both Claude and Claude Code.
