Anthropic has finally confirmed the existence of Claude Mythos, but they will not release the model publicly, because it isa “cybersecurity reckoning.”��Instead, they have organized a 40-company coalition called “Project Glassing” to allow cybersecurity professionals a head start in locking down critical software. This is an urgent initiative and it’s time to pay attention to alignment, because these models are getting seriously capable. Mythos’ benchmarks are absurd: It scored 77.8% on SWE_bench Pro, versus 53.4% for Opus 4.6. 59% on SWE-bench multimodal, versus 27.1% for Opus 4.6 That should give you an idea. It is a tremendous leap. Imagine what you will be able to build with Mythos when it eventually drops. Also imagine, the damage you could do with it If they were to prematurely release it… #anthropic #claude #mythos

Introducing Project Glasswing: an urgent initiative to help secure the world’s most critical software. It’s powered by our newest frontier model, Claude Mythos Preview, which can find software vulnerabilities better than all but the most skilled humans.

Anthropic just built an AI model so powerful they won’t release it to the public 🔒 It’s called Claude Mythos - and it scores way higher than Opus 4.6, the model behind Claude Code right now. We’ve already seen designers ship full apps, design systems, and entire UX flows without writing a single line of code. When Mythos powers Claude Code, it could be the biggest upgrade to how we design with AI. Follow @adrien.ninet for more AI design tips! #aidesign #claudeai #designworkflow #aifordesigners #uidesign

Whispered my way through a whole breakdown so I wouldn’t wake the kids 😅 This is one of the most significant announcements I’ve seen Anthropic just announced Project Glasswing and Claude Mythos Preview …. a model so capable they decided not to release it publicly. They found thousands of zero-day vulnerabilities across every major OS and browser. Bugs that survived 27 years of human review. Code that automated tools hit five million times without catching it. The name comes from the glasswing butterfly🦋 whose transparent wings let it hide in plain sight. Just like the vulnerabilities this model finds. Instead of shipping it, they assembled a $100M coalition — AWS, Apple, Google, Microsoft, NVIDIA, CrowdStrike and others - to patch the world’s infrastructure before this capability gets into the wrong hands. The benchmarks are honestly wild! [tech news, artificial intelligence, Claude, Machine learning]

Anthropic’s new AI bot is one of the world’s most powerful hacking tools—and could turn the private company into a geopolitical force, Matteo Wong argues. “For the past several weeks, Anthropic says it secretly possessed a tool potentially capable of commandeering most computer servers in the world,” Wong reports. “This is a bot that, if unleashed, might be able to hack into banks, exfiltrate state secrets, and fry crucial infrastructure.” “For now, the bot will be available only to a consortium of many of the world’s biggest tech companies—including Apple, Microsoft, Google, and Nvidia.” Wong reports. These partners can use the bot, Claude Mythos Preview, “to scan and secure bugs and exploits in their software. Other than that, Anthropic will not immediately release Mythos Preview to the public, having determined that doing so without more robust safeguards would be too dangerous.” Mythos Preview has already identified thousands of major cybersecurity vulnerabilities—including exploits in every single major operating system and browser, Wong writes. This kind of capability is typically available only to elite, state-sponsored hacking cells. “Now it’s in the hands of a private company,” Wong writes. “For years, cybersecurity experts have been warning about the chaos that highly capable hacking bots could usher in,” Wong continues. “As a result of how capable AI models have become at coding, they have also become extremely good at finding vulnerabilities in all manner of software. Even before Mythos Preview, AI companies such as Anthropic, OpenAI, and Google all reported instances of their AI models being used in sophisticated cyberattacks by both criminal and state-backed groups.” “Still, Mythos Preview appears to represent not an incremental change but the beginning of a paradigm shift,” Wong argues at the link. 🎨: Matteo Giuseppe Pani / The Atlantic
