[Mythos Model Reportedly Accessed by Unauthorized Users; Anthropic Once Claimed Its Technology Is Extremely Powerful] According to a report by Jinse Finance on April 22, documents reviewed by the media and information from an insider reveal that a small number of unauthorized users have gained access to Anthropic PBC's next-generation Mythos AI model. Anthropic previously stated that the model's technology is extremely powerful and could even be used to launch dangerous cyberattacks. An individual, who requested anonymity due to fear of retaliation, disclosed that on the same day Anthropic first announced plans to open the Mythos model for testing to a select number of companies, a small group of users on a private online forum successfully accessed Mythos. The insider stated that this group has since been using Mythos regularly, though not for cybersecurity purposes. The claims were substantiated by the insider through screenshots and live demonstrations of the model to the media. This unauthorized access had not been disclosed previously, highlighting the challenges Anthropic faces in fully preventing the spread of its most powerful—and potentially most dangerous—technology beyond authorized partners. The incident also raises further questions: Are there others using Mythos without permission, and what are their intentions? (Zhitong Finance)
