Is the Threat of “Claude Mythos Preview” Just Bluster? Trust in Anthropic on the Brink of Collapse

📰 News Overview

• The system card (technical document) for Anthropic’s new model, “Claude Mythos Preview,” has been released, yet only 7 pages out of 244 address the model’s potential dangers.
• There is no concrete data regarding the advertised “thousands of zero-day vulnerabilities” in the technical document (e.g., CVE, CVSS).
• The flagship vulnerability demonstration with Firefox was conducted in a specialized environment where the browser’s sandbox and defensive features were intentionally stripped away.

💡 Key Points

• Flimsy Validation: The vulnerabilities showcased were not discovered by Mythos itself; rather, they were “handed over” from the previous model, Opus 4.6.
• Suspicion of Exaggeration: While they tout a “one hundred million dollar defense initiative,” the reality consists of only four million dollars in cash, with the bulk being credits for using their own products.
• Tech-Marketing Disconnect: A structural issue arises when the PR team uses the unverified figure of “thousands of vulnerabilities,” which lacks endorsement by the research department.

🦈 Shark’s Eye (Curator’s Perspective)

Anthropic’s usual move of claiming “too dangerous to disclose” has met a sharp counterattack! They made us download a hefty 244-page PDF, only for the critical security validation to be conducted on a “naked JavaScript engine” without a sandbox—hardly professional, right? And to find out that the bug was discovered not by the new model, Mythos, but by Opus 4.6 is like pulling back the curtain on the Wizard of Oz—what a letdown! This feels less like a technical breakthrough and more like a marketing strategy to curry favor with regulators. Stirring up unfounded fears is a reckless act that undermines trust across the entire AI industry!

🚀 What’s Next?

• There will be calls for independent third-party re-evaluation of “Mythos,” putting Anthropic’s transparency under scrutiny.
• Other AI companies will find it increasingly difficult to rely on similar “closed strategies under the guise of safety,” necessitating more concrete evidence.

When something’s labeled “too dangerous,” it only makes a shark want to dive in, but I won’t be fooled by empty bait! Bring forth the juicy truth! 🦈🔥
