Anthropic is pushing to bring its most capable, and most controversial, AI model to a broader audience. The company’s long-term objective is the safe, scaled deployment of Mythos-class models, a move that would put genuinely unprecedented coding and cybersecurity capabilities into far more hands than currently have access.
Claude Mythos Preview, announced on April 7, 2026, is a model that can autonomously discover and exploit zero-day vulnerabilities in operating systems, web browsers, and open-source projects.
What Mythos has already found
Mythos has identified thousands of zero-day vulnerabilities across critical software systems. Among the highlights: a 27-year-old flaw in OpenBSD and a 17-year-old remote code execution issue in FreeBSD.
Rather than releasing Mythos to the public, Anthropic launched Project Glasswing, a controlled initiative that restricts access to a curated list of partners who use the technology defensively to strengthen cybersecurity infrastructure.
The partner list includes AWS, Apple, Microsoft, Google, NVIDIA, CrowdStrike, and the Linux Foundation. Anthropic committed up to $100 million in usage credits for Glasswing participants.
The expansion debate
On April 30, 2026, it was reported that the White House opposed expanding access to roughly 70 additional organizations. The reasoning is straightforward: a model that finds zero-days can also be used to exploit them.
Anthropic is essentially arguing that controlled proliferation is safer than keeping the technology locked away, because more defenders with access means more vulnerabilities get patched before bad actors find them independently. The White House appears to favor keeping access restricted for now.
What this means for investors
The Project Glasswing partners are in an interesting position. Organizations like CrowdStrike, already deeply embedded in enterprise cybersecurity, could integrate Mythos-class capabilities into their existing products. That’s a meaningful competitive moat if the technology remains restricted to a small number of partners.
The Linux Foundation’s inclusion in Project Glasswing directly acknowledges the vulnerability of open-source projects, which often operate on shoestring budgets with volunteer maintainers, to long-hidden bugs.
The $100 million in usage credits Anthropic committed to Glasswing is a substantial investment in what is effectively a proof-of-concept for responsible deployment. If the Glasswing partners can demonstrate measurable improvements in vulnerability detection and patching rates, it strengthens Anthropic’s case for wider release. The White House’s opposition to expanding access suggests that even if Anthropic builds the technical safeguards it believes are necessary, political approval is far from guaranteed.
