Claude Opus 4.5 (November 2025) was already a step change in model quality and was when the reality of AI agents started to match the hype.
The idea of an even more capable being launched so soon afterwards is amazing progress and also a little scary.
"A draft blog post that was available in an unsecured and publicly searchable data store prior to Thursday evening said the new model is called Claude Mythos and that the company believes it poses unprecedented cybersecurity risks."
"Anthropic acknowledged that a “human error” in the configuration of its content management system led to the draft blog post’s being accessible"
lol - is this Anthropic trying to demonstrate that people are fully of being cybersecurity risks without #AI or Actual Irony
