Alleged Leak of Anthropic's Mythos Model Sparks Security Concerns

A recent claim circulating online suggests that a Mythos-class artificial intelligence model developed by Anthropic has been leaked on the platform Hugging Face. The report, which appeared on the discussion site Hacker News, has prompted widespread skepticism regarding its authenticity.

Industry observers and technical commenters are largely dismissing the leak as a probable hoax. Critics point out that this incident follows a recent pattern of suspicious claims, including a separate report regarding a “Fable 5” model checkpoint allegedly being sold on dark web forums. Many participants in the discussion suggested that the primary intent behind these alleged leaks is to entice users into downloading and executing malicious software under the guise of accessing proprietary AI technology.

The technical requirements of the alleged file have also fueled doubts. With the purported model size reaching approximately eight terabytes, experts noted that it is not a file that an inexperienced user could easily download or execute on a standard machine.

Furthermore, some users have highlighted that previous reports of similar leaks, such as an alleged leak of Anthropic’s Claude 2.1 model, were ultimately proven to be fraudulent, consisting merely of existing, open-source models that had been renamed to deceive the public. Regarding the current situation, commenters speculated that if a malicious actor were involved, the goal might be to distribute a “poisoned” model. Such a file could theoretically exploit vulnerabilities in inference software or tool-use harnesses if a user were to attempt to run it. However, most experts noted that individuals capable of setting up the necessary infrastructure to run an eight-terabyte model would likely be sophisticated enough to inspect the file structure and identify that the “Mythos” architecture does not correspond to any known, functional software.

As of now, there is no verified evidence that Anthropic has released any such model to the public. The discussion continues to serve as a warning about the risks associated with downloading unverified files from internet forums, particularly those masquerading as high-profile corporate technology releases.
