Strengthening our defenses against distillation attacks
Illicit distillation allows model developers to copy frontier AI capabilities without creating proportionally robust safeguards. Here, we describe how we’ve reduced the rate of distillation by more than 90%.
Introducing the Anthropic Cyber Mission
We’re launching the Anthropic Cyber Mission, a long-term commitment to securing the systems everyone depends on.
Measuring tactical intelligence targeting and conventional weapons capabilities of AI models
Anthropic’s Frontier Red Team developed new evaluations to measure AI capabilities in tactical intelligence targeting and conventional weapons development.
Discovering cryptographic weaknesses with Claude
Cryptographic algorithms. The first attack significantly weakens HAWK, a digital signature scheme that was built for a future world where quantum computers are able to break existing standards. The second identifies a new way to attack round-reduced AES, the most widely used symmetric cipher.
Our position on open-weights models
Anthropic CEO Dario Amodei on open-weights models
Fable 5 returns globally July 1. We're also proposing an industry-wide framework for scoring jailbreak severity, together with Amazon, Microsoft, Google, and other Glasswing partners.
Statement on the US government directive to suspend access to Fable 5 and Mythos 5
The US government has issued an export control directive to suspend all access to Fable 5 and Mythos 5.
Expanding Project Glasswing
We’re extending Project Glasswing to approximately 150 new organizations in more than fifteen countries.

Detecting and preventing distillation attacks
We have identified industrial-scale campaigns by three AI laboratories—DeepSeek, Moonshot, and MiniMax—to illicitly extract Claude’s capabilities to improve their own models.
Experimenting with AI to defend critical infrastructure
AI could help defenders of critical infrastructure identify the vulnerabilities that attackers might exploit—and close them before they are exploited. Anthropic has partnered with Pacific Northwest National Laboratory (PNNL) to explore this defensive application of AI, demonstrating both the potential of AI-accelerated defense and the value of public-private partnerships in harnessing AI for national security.

Updating restrictions of sales to unsupported regions
To account for this reality and better align with our commitment to ensuring that transformative AI capabilities advance democratic interests, we are strengthening our regional restrictions.
Detecting and countering misuse of AI: August 2025
We’ve developed safeguards to prevent the misuse of our models, but malicious actors are actively attempting to find ways around them. Today, we’re releasing a report that details how.
Introducing the Anthropic National Security and Public Sector Advisory Council
We are announcing the formation of the Anthropic National Security and Public Sector Advisory Council, a group of leading bipartisan national security and public policy practitioners who will help Anthropic support the U.S. government and closely allied democracies in building and maintaining enduring technological advantages in an era of strategic competition.
Developing nuclear safeguards for AI through public-private partnership
Together with the NNSA and DOE national laboratories, we have co-developed a classifier that distinguishes between concerning and benign nuclear-related conversations with 96% accuracy in preliminary testing.
Developing nuclear safeguards for AI
Together with the NNSA and DOE national laboratories, we have co-developed a classifier—an AI system that automatically categorizes content—that distinguishes between concerning and benign nuclear-related conversations with high accuracy in preliminary testing.
Federal government departments and agencies can now purchase Claude through the GSA schedule
