OpenAI, Anthropic, Google, Microsoft, and 100+ orgs call for a cyber-defense surge

OpenAI, joined by Anthropic, AWS, Google, Microsoft, Oracle, and more than 100 other organizations, called for a global surge in cyber defense while a “defenders’ window” still exists—using the same model progress to find and fix years of accumulated vulnerabilities before AI-enabled attacks scale. The open letter urges funding defensive AI, sharing threat intel, tightening access to sensitive systems, and hardening critical infrastructure. For anyone running unsandboxed evals, coding agents, or tool-using models, it is a post-incident signal from frontier labs that defensive tooling now sits on the same clock as capability.
