 | To save you from digging through their 244-page system card, I highly recommend checking out this video breakdown [Link:https://www.youtube.com/watch?v=PQsDXTPyxUg]—it perfectly breaks down why the "safety risk" excuse in my meme above is really just about astronomical compute costs. Anthropic is heavily pushing the narrative that Claude Mythos Preview is a god-tier model that is simply "too dangerous" to release because it can find zero-days in OpenBSD. But if you swipe to the second image (page 21 of their system doc), the illusion falls apart. They didn't just ask Mythos a question. They used uncensored checkpoints, stripped the guardrails, gave it extended thinking time, strapped it to domain-specific tools, and brute-forced it thousands of times at a massive compute cost (reportedly ~$50 per run). The single-shot probability of it finding a bug is likely fractions of a percent. This isn't a "dangerous" model; it's just an unscalable API cost wrapped in a PR campaign. We are already seeing this exact same agentic scaling in the open-source and local communities:
Even in the closed-source space, if you drop OpenAI's GPT-5.4 into the Codex app on the xhigh reasoning tier and let it run autonomously for 8+ hours with full codebase access, it is going to brute-force its way to 20 critical bugs while you sleep. Finding zero-days in 2026 is a factor of agentic tooling and massive compute budgets, not a magical leap in raw model intelligence. Don't let Anthropic's "extinction-level threat" marketing convince you that the open-source community is falling behind. [link] [comments] |
