Anthropic Locks Down 'Dangerous' Mythos AI, Restricting Public Access
Anthropic announced on April 10, 2026, its decision to limit access to Claude Mythos, citing the model's exceptional prowess in identifying security flaws across critical digital infrastructure. The company revealed that Mythos has already exposed tens of thousands of vulnerabilities, including deeply embedded weaknesses in every major operating system and web browser currently in use. This includes the discovery of a 27-year-old bug in a crucial piece of security infrastructure and multiple critical vulnerabilities within the Linux kernel, foundational to countless computer systems worldwide.
The model, in some iterations referred to as Claude Mythos 5, is reported to possess an astounding 10 trillion parameters, positioning it at the cutting edge of AI capabilities. Anthropic's internal assessments demonstrated the model's advanced autonomy, revealing its capacity to chain exploits across disparate systems, a capability that significantly elevates the risk of misuse if placed in malicious hands.
Rather than a broad release, Anthropic has initiated “Project Glasswing,” an exclusive preview program granting a consortium of approximately 50 carefully selected technology and cybersecurity organizations access to Claude Mythos. Key industry players such as Amazon, Apple, Cisco, JPMorgan Chase, Microsoft, and Nvidia are reportedly among the participants in this defensive initiative. The explicit aim is to empower these entities to proactively identify and patch security vulnerabilities within their own systems, effectively hardening global defenses before similar AI capabilities inevitably emerge more broadly or are weaponized by threat actors.
The decision to withhold Claude Mythos from public availability, including a public API, underlines a growing apprehension within the AI development community regarding the rapid acceleration of AI's potential for harm. The company stated that the time between the public release of a new AI capability and its weaponization by malicious actors has dramatically shortened in 2025, a trend expected to accelerate further in 2026. This reflects a significant philosophical divergence emerging within the AI landscape, pitting the traditional drive for innovation against increasingly urgent safety and ethical considerations.
Under the terms of Project Glasswing, access to the Mythos model is priced at $25 per million input tokens and $125 per million output tokens, a premium reflecting its specialized and sensitive nature. This controlled deployment represents a pragmatic, albeit controversial, approach to managing the immediate risks posed by hyper-capable AI models, acknowledging that preventing malicious exploitation requires a collaborative, preemptive defense strategy.
While Anthropic moves to secure its most potent creation, the broader industry continues to grapple with the implications of such powerful tools. Concurrently, other significant developments underscore the dynamic nature of the AI sector. CoreWeave, an AI-focused cloud infrastructure provider, announced a multi-year agreement with Anthropic on April 10, 2026, to support the development and deployment of Anthropic's Claude family of AI models, a deal that followed CoreWeave's separate announcement of raising $3.5 billion in convertible debt to expand its AI infrastructure.
This capital infusion highlights the immense demand for the underlying compute power necessary to train and run these increasingly complex AI systems, even as questions persist about their ultimate safety and societal impact. The contrast between massive investment in AI infrastructure and the strategic suppression of a breakthrough model due to its inherent risks reveals a sector navigating profound tensions.
As regulatory bodies, like those in the United States and Europe, continue to debate comprehensive AI governance frameworks, the industry is increasingly forced to self-regulate in real-time. Anthropic's decision with Claude Mythos may set a precedent for future releases of highly capable, potentially dangerous AI, but it also raises fundamental questions about who ultimately controls such powerful technology and what mechanisms exist to ensure its responsible development beyond the confines of a select few corporations.
