Apple Joins Anthropic's Project Glasswing: Mythos AI, NSA Controversy, and the Quiet End of Apple's 'Build-Our-Own-AI' Era

TL;DR: Apple has joined Anthropic’s Project Glasswing, a twelve-company consortium that gets preview access to Claude Mythos — a model Anthropic describes as powerful enough to find “thousands of high-severity vulnerabilities” in every major operating system and browser. Anthropic has explicitly said Mythos Preview will not be made generally available. Separately, Heise and the Financial Times report that roughly half a dozen Anthropic engineers are working on-site with the NSA to adapt Mythos for offensive cyber operations against adversary networks. The two threads together mark a strategic shift: Apple is no longer pretending it will train a frontier foundation model in-house. It is now an integrator of third-party AI for its most security-sensitive workloads.
