Mythos meltdown: comment war!
A Boy That Cried Mythos: Verification Is Collapsing Trust in Anthropic
Receipts or hype? Commenters roast Anthropic’s ‘Mythos’ claims
TLDR: A viral critique claims Anthropic hyped scary security powers for its Mythos AI without showing evidence in its long “system card.” Commenters are split: some cry hype and demand public bug details, others say NDAs and the difficulty of real exploits explain the silence—trust in AI buzz is on trial.
Anthropic’s scary-sounding “Mythos” preview promised a model that could uncover “thousands” of software flaws—but the 244-page “system card” (a company doc explaining risks and safeguards) reportedly devotes just seven pages to security, with no public bug list. Cue comment chaos. One baffled reader asked, “Am I supposed to know what a system card is?” while others turned the author’s “sad trombone” punchline into a meme. The vibe: show the receipts, or stop the spooky marketing.
The thread split fast. The cynics say this is doom marketing that sells fear while Anthropic’s launch blog shouts “thousands” and the tech doc whispers “trust us.” Some even joked the whole drama masks a compute crunch: “data centers are already on fire.” Others pushed back: a top reply insists that writing a working hack is the hard part, so “it just can’t exploit” is not a dunk—it’s the ballgame. A calmer middle argues an NDA or “responsible disclosure” could be delaying details, and that partners might be gagged from confirming anything. Meanwhile, a separate pile-on targets the author’s past “nonsense vulnerabilities.” Glossary check for the non-nerds: CVE is a public bug ID, CVSS is a severity score, CWE is a weakness type—commenters want those receipts on paper, not vibes. Until then, it’s Mythos or myth—and trust is wobbling.
Key Points
- •The author states the Claude Mythos system card is 244 pages, with about seven pages addressing cybersecurity claims.
- •The article claims the system card lacks details such as CVE lists, CVSS distributions, baselines, independent reproduction, and common terms like fuzzer, CVSS, CWE, CVE.
- •The flagship demonstration allegedly involved exploiting two already-patched bugs in a de-sandboxed test environment, reducing real-world relevance, per the author.
- •The often-cited “thousands of zero-days” figure appears in blog/announcement materials but is not quantified in the system card’s cybersecurity section, according to the article.
- •Project Glasswing’s $100M initiative is described as $4M cash and $100M in product credits, with no public 90-day report yet and no partner-confirmed findings, per the author.
