- Anthropic announced Project Glasswing, a cybersecurity initiative using its Claude Mythos Preview model to find and fix software vulnerabilities, in partnership with Amazon Web Services, Apple, and Broadcom
- The Claude Mythos Preview is not being released publicly — Forbes, Neowin, Sherwood News, and The Deep View frame it as "too dangerous" to ship, while Bloomberg reports Apple and Amazon are among select partners granted access
Why it matters: Anthropic is openly marketing a model it won't sell, handing access to a curated partner roster (AWS, Apple, Broadcom) rather than the public — a distribution model that turns safety claims into a competitive moat. The misalignment between "withheld" rhetoric and the fact that named partners are already testing it is the story beneath the safety narrative.
