Anthropic announced that export controls on Fable 5 and Mythos 5 had been lifted and that Fable 5 would be redeployed globally from July 1, 2026 with an improved safety classifier. Anthropic says the classifier blocks the technique described in an Amazon report in over 99% of cases and that CAISI researchers tested its prior and new safeguards. Mythos 5 access was restored for a set of US organizations after government approval on June 26.

Executive Order 14409 directs Treasury, NSA and CISA to develop a classified benchmarking process to assess advanced cyber capabilities of AI models and designate covered frontier models, with a voluntary framework for pre-release government and trusted-partner access. It also orders an AI cybersecurity clearinghouse to coordinate vulnerability scanning, validation and remediation with industry, and states it does not create mandatory licensing or pre-clearance.

The Trump administration's Cyber Strategy for America commits to securing the AI technology stack, adopting AI-powered cybersecurity for federal networks, and using AI-enabled tools to detect, divert and deceive threat actors. It states the US will rapidly adopt and promote agentic AI to securely scale network defense and disruption.

The White House AI Action Plan recommends establishing an AI Information Sharing and Analysis Center led by DHS with CAISI and the National Cyber Director, DHS guidance on AI-specific vulnerabilities, and updates to CISA incident response playbooks for AI systems. It also directs CAISI to evaluate frontier models for national security risks including cyberattacks, and to assess adversary AI systems for backdoors. As of February 2026, a CISA official described the AI-ISAC as still a pre-decisional memo.

President Biden's executive order on safe, secure and trustworthy AI defined dual-use foundation models partly by their potential to enable offensive cyber operations through automated vulnerability discovery and exploitation. It required developers to report red-team results to the government and directed a federal pilot using AI to find and fix vulnerabilities in government systems. The order was revoked by Executive Order 14179 on January 23, 2025.
