What is Project Glasswing and who is in it?: Project Glasswing is Anthropic's restricted-access programme for Claude Mythos Preview.

Why did Anthropic not release Mythos publicly and create Glasswing instead?: Anthropic withheld Mythos from public release because the model can autonomously chain 32-step cyberattacks equivalent to 20 human hours of work, posing offensive cybersecurity risk if broadly accessible.

Background

Project Glasswing is Anthropic's restricted-access programme for Claude Mythos Preview, launched on 8 April 2026. It distributes the model exclusively to vetted partner organisations alongside $100 million in model usage credits each, with JPMorgan Chase publicly identified as one partner. Following Anthropic's 7 April system card, the partner list expanded by five to seventeen organisations, adding Broadcom, CrowdStrike, NVIDIA, Palo Alto Networks, and Cisco. The programme's structure — vetted partners, credit allocations rather than open pricing, and no public release — represents an unusual approach to frontier model deployment, driven by Anthropic's assessment that Mythos poses unacceptable offensive cybersecurity risk if widely accessible.

The Glasswing name draws on the glasswing butterfly, whose transparent wings make it difficult for predators to track — an apt metaphor for a programme designed to distribute powerful capability while maintaining opacity about its full partner list and usage conditions. The 7 April Alignment Risk Update also marked a methodology shift: Anthropic abandoned ASL (AI Safety Level) capability benchmarks in favour of autonomy-focused threat models, meaning the criteria partners must demonstrate they can handle have changed alongside the expanded list.

The programme's existence became publicly significant when the US Treasury and Federal Reserve convened an emergency meeting with five bank CEOs specifically to discuss Mythos — with JPMorgan's CEO, already a Glasswing partner, notably absent. The UK's AISI subsequently published an independent evaluation confirming a 32-step attack chain equivalent to 20 human work-hours — the first independent verification of Mythos capability. Glasswing sits at the centre of a new policy question: whether government should have visibility into which organisations receive frontier AI access before broader deployment.

How the World Sees Them

Anthropic

Glasswing is positioned as responsible deployment: restricting a dangerous capability to vetted actors rather than open release, with $100M credits as the access mechanism.

US government

The Treasury-Fed emergency meeting suggests regulators were not fully pre-briefed on Glasswing partners or Mythos capabilities before the programme launched.

Financial sector

Glasswing partners gain a structural cybersecurity advantage; banks outside the programme face asymmetric exposure if adversaries access Mythos through other means.

Open-source advocates

Critics argue that a private, non-transparent list of approved AI users concentrates power and is the opposite of accountable governance.
