Anthropic's Mythos model accessed by unauthorized users, Bloomberg News reports

A handful of users in a private online forum gained access to Mythos on the same day that Anthropic first announced ‌a plan to ⁠release the model... The group has been using Mythos regularly since then, though not for ​cybersecurity purposes... Announced on April 7, Mythos is being deployed as part of ‌Anthropic's "Project Glasswing," a controlled ​initiative under which select organizations ​are permitted ​to use the unreleased Claude Mythos ‌Preview model for defensive ​cybersecurity. Mythos is ​a powerful AI model that has sparked concerns among regulators about its unprecedented ​ability to ‌identify digital security vulnerabilities and potential for ​misuse.
