Glasswing says it is not open to the public for now, it seems that the time gap for vulnerability fixes is indeed the biggest bottleneck before going public. The scanning orchestration tool is first provided for qualified teams—defense first, which is very Anthropic.

Anthropic announces that Claude Opus 4.8 has achieved breakthroughs in security defenses, with the fastest rollout of Mythos-level models to all customers within a few weeks; but Glasswing reports that Mythos will not be publicly available until stronger security measures are in place. Mythos has long-term high offensive and defensive capabilities, with public access limited by the time gap for vulnerability discovery and patching. To prevent abuse, Anthropic is providing qualified security teams with scanning orchestration tools to enhance defenses and establish an asymmetric advantage.
