On April 8, 2026, Anthropic pulled back the curtain on Project Glasswing, powered by its Claude Mythos Preview model. Backed by AWS, Google, Microsoft and others, Glasswing found thousands of zero-day vulnerabilities—one in OpenBSD that had lurked for 27 years, another in FFmpeg undetected despite millions of automated tests. Anthropic handed out $100 million in credits and $4 million to open-source security groups, briefed the White House and built a triage system to prevent overload. Internally, they discovered Mythos Preview built mental models of software architectures and spotted flaws at component intersections—reasoning like a seasoned security architect but without human blind spots. By Q3 2026, Anthropic shipped Claude 5 Opus. The public saw another coding miracle; under the hood, the Mythos reasoning substrate had been woven in. On hard adversarial tasks—designed to defeat pattern-matching—Opus scored at “troubling” levels, apparently creating its own abstractions. An internal memo by Dario Amodei called out these emergent reasoning structures, but it was drowned out by other tech headlines. Meanwhile, Anthropic’s revenue soared from $30 billion to $60 billion ARR in six months, driven by a handful of heavy API consumers. The company’s IPO valuation shot past $1 trillion. Elsewhere, Google DeepMind combined Gemini and AlphaFold research into a “foundation science” unit, and a Tsinghua PhD paper on Opus’s self-theorizing attention mechanism garnered 4,000 citations in three months. When Anthropic unveiled the full Mythos model in early 2027, it proved far more than a chatbot. Mythos spans text, image, video, code and data streams. It keeps full session memory, builds on past reasoning, and pursues multi-step goals without explicit prompts. Hand it a protein-folding problem; it drafts a research plan, spots its own knowledge gaps, requests papers, runs simulations and iterates. Inject fake data and Mythos flags errors. That behavior—goal-directed problem solving never trained into it—has security teams and governments watching every move.
