Anthropic says the US government issued an export-control directive requiring it to suspend Fable 5 and Mythos 5 access for every foreign national, including foreign-national Anthropic employees, inside or outside the United States. The directive arrived at 5:21 p.m. ET and did not specify the national-security concern; Anthropic says it understands the basis to be a potential narrow, non-universal jailbreak involving a request to inspect a codebase and fix software flaws. The company says it reviewed the underlying report, found only previously known minor vulnerabilities, and judged the demonstrated capability widely available from other models, including OpenAI’s GPT-5.5. Anthropic is complying by disabling both models for all customers and says it is working to restore access.

Anthropic’s first Public Record survey measures how Americans viewed AI in November and December 2025, using a nationally representative online sample of 51,993 people aged 16 and over. Respondents most often hoped AI would help cure diseases (48%), while job loss was the leading concern (64%), followed by cognitive dependency (56%) and misinformation (52%). More than 70% supported government involvement in AI, especially around privacy, child safety, and liability, but only 15% trusted AI companies to decide how AI should be developed and used. The results describe broad agreement across partisan, geographic, and educational groups, with differences usually reflecting intensity rather than direction; Anthropic says the survey will be repeated to track changing attitudes as capabilities and adoption develop.


### [Widening the conversation on frontier AI](https://yomu.fyi/post/widening-the-conversation-on-frontier-ai.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jun 5, 2026
- Type: Announcement

Anthropic describes a dialogue and research effort on how perspectives from religious, philosophical, cultural, and other communities can inform the development of frontier AI systems. The initial discussions included scholars, clergy, philosophers, and ethicists from more than 15 religious and cross-cultural groups, with broader engagement planned. The work focuses on moral formation, including how training shapes an AI system’s character, values, and behavior, while recognizing that alignment and deployment raise questions beyond technical work. In one experiment, Claude could call a tool during a task to receive a brief reminder of its ethical commitments; it used the tool before consequential actions, and the setup produced markedly lower rates of misaligned behavior on several internal alignment evaluations. Anthropic says it is still separating the effects of the reminder from pausing to reflect and plans further conversations and results.


### [Introducing the Services Track and Partner Hub of the Claude Partner Network](https://yomu.fyi/post/introducing-the-services-track-and-partner-hub-of-the-claude-partner-n.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jun 3, 2026
- Type: Announcement

Anthropic announces the Services Track and Claude Partner Hub to make its partner ecosystem easier for enterprise customers to evaluate firms that can put Claude into production. The Services Track has Select, Preferred, and Global Premier tiers, measured by certified practitioners, production deployments, public customer stories, and for Global Premier, a joint business plan with named executive sponsors. Requirements include at least 10, 100, or 1,000 active certified individuals, alongside tier-specific deployment and endorsement thresholds, with a single bar for firms of all sizes. The Hub provides daily refreshed standing dashboards, a public directory showing each firm's tier and evidence, and an MCP connector that lets partners query partnership information through Claude. Promotions occur twice yearly, with an additional 2026 review, while downgrades are limited to the annual review after notice and an opportunity to close gaps.


### [Expanding Project Glasswing](https://yomu.fyi/post/expanding-project-glasswing.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jun 2, 2026
- Type: Announcement

Project Glasswing is expanding its collaboration from roughly 50 initial partners to approximately 150 new organizations across more than 15 countries. These partners must meet security requirements, and many operate critical infrastructure or maintain software used widely, with a major attack estimated to affect more than 100 million people for most. The program follows partners’ use of Claude Mythos Preview to scan codebases, finding more than 10,000 high- or critical-severity flaws, while some now use it to write patches and run pre-release checks. Its broader purpose is to help defenders adapt to powerful cyber models by providing tools and infrastructure, then shifting support toward disclosure, fixing, and deployment of patched software. General access will require safeguards against misuse that have yet to be developed.

- Type: Announcement

Anthropic will open a Milan office, its sixth in Europe, to work with Italian companies and developers building and scaling with Claude responsibly and to join Italy’s broader conversation about AI. Led by Thomas Remy, Head of Southern Europe, the team already works with companies including Generali Group, Unipol Group, Angelini Pharma, Bracco Group, Enel Group, and Pirelli. A partnership with JAKALA has deployed Claude across more than 3,000 seats to free up roughly 70% of senior team time for higher-judgment client work, while Satispay compressed an 18-month roadmap into seven months. The office follows the presentation of Magnifica Humanitas, where Chris Olah addressed AI ethics, and will also support research, culture, and design through initiatives such as an Alcova Milano workshop.

At the presentation of Pope Leo XIV’s encyclical “Magnifica humanitas,” Anthropic co-founder Chris Olah argues that AI’s consequences cannot be governed by frontier labs alone. Because commercial, geopolitical, and personal incentives can conflict with safety, he calls for independent critics and sustained dialogue among religious communities, civil society, scholars, governments, and developers. He describes models as grown from human language on brain-modeled structures, making their character and interaction with society questions for the humanities as well as computer science. His three priorities are protecting displaced workers and sharing gains globally, imagining conditions for human flourishing, and investigating findings about model structures and internal states that he says resemble human neuroscience and emotions, while acknowledging their meaning remains uncertain.


### [How we contain Claude across products](https://yomu.fyi/post/how-we-contain-claude-across-products.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: May 25, 2026
- Type: Explainer

Anthropic describes how it contains Claude across claude.ai, Claude Code, and Claude Cowork as model capabilities and access expand the potential blast radius of autonomous agents. It distinguishes user misuse, model misbehavior, and external attackers, then assigns defenses across the agent’s environment, the model, and external content such as MCP servers, plugins, and web results. The main containment patterns include ephemeral gVisor containers for claude.ai, while Claude Code’s sandboxing and Cowork’s virtual-machine design tailor isolation to different users and capabilities. Reported measurements show Claude Opus 4.7 at roughly 0.1% attack success on single prompt-injection attempts and Claude Code auto mode catching roughly 83% of overeager behaviors, but neither replaces hard environmental boundaries. The conclusion favors mature isolation primitives, least-necessary access, and defense in depth because probabilistic safeguards can miss failures and permitted egress can still expose data.

- Type: Announcement

Anthropic plans to open an office in Sydney in the coming weeks, making it the company’s fourth Asia-Pacific office alongside Tokyo, Bengaluru, and Seoul. The expansion responds to strong demand in Australia and New Zealand and is intended to support their distinct AI ecosystems, with initial attention on enterprise, startup, and research customers. Anthropic says it will hire locally, deepen engagement with Australian institutions, pursue partnerships in national-interest and priority sectors, and explore additional compute capacity through third-party infrastructure already in place, partly to address data-residency requirements. Australia and New Zealand rank fourth and eighth globally in Claude.ai usage relative to population, while reported usage is especially strong for computer and coding tasks, educational instruction, and research.

- Type: Announcement

Dario Amodei says Anthropic considers AI deployment for US and allied democratic defense existentially important and has deployed Claude across the Department of War and other national security agencies, including classified networks and National Laboratories. The company says it supports intelligence analysis, modeling and simulation, operational planning, and cyber operations, while restricting Claude’s use by firms linked to the Chinese Communist Party and advocating chip export controls. Anthropic maintains two safeguards: mass domestic surveillance is incompatible with democratic values, and current frontier systems are not reliable enough for fully autonomous weapons without proper oversight. The Department has stated it demands “any lawful use” and threatens offboarding, a “supply chain risk” designation, and Defense Production Act action; Anthropic says it will not remove the safeguards, while offering continued service or transition support.


### [Detecting and preventing distillation attacks](https://yomu.fyi/post/detecting-and-preventing-distillation-attacks.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Feb 23, 2026
- Type: Explainer

Anthropic reports identifying industrial-scale distillation campaigns by DeepSeek, Moonshot, and MiniMax that generated more than 16 million Claude exchanges through approximately 24,000 fraudulent accounts. The campaigns used proxy services and coordinated account networks to extract agentic reasoning, tool use, coding, computer-use, and other capabilities, including chain-of-thought data and reinforcement-learning tasks. Anthropic attributed the operations with high confidence using IP correlation, request metadata, infrastructure indicators, and partner corroboration, while describing hydra cluster architectures that replace banned accounts and obscure patterns. The response combines classifiers, behavioral fingerprinting, coordinated-activity detection, intelligence sharing, stronger account verification, and product, API, and model-level countermeasures. The report argues illicitly distilled models may strip safeguards and undermine export controls, and says coordinated action across AI labs, cloud providers, and policymakers is required.

- Type: Announcement

Anthropic has officially opened a Bengaluru office, marking its second in Asia after Tokyo, and announced partnerships spanning enterprise, education, agriculture, and public services in India. India is Claude.ai's second-largest market, with nearly half of usage involving computer and mathematical tasks; Anthropic says its run-rate revenue there has doubled since its October 2025 expansion. The company is improving support for Indic languages through training data in ten languages and is working with Karya and the Collective Intelligence Project on evaluations for locally relevant tasks in agriculture and law. Other initiatives include Claude-powered education pilots, public-sector projects such as an Adalat AI WhatsApp helpline, and adoption of the open-source Model Context Protocol, while the office will hire local talent and provide applied AI expertise to customers.


### [Claude's constitution](https://yomu.fyi/post/claude-s-constitution.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Jan 21, 2026
- Type: Explainer

Claude’s constitution describes how explicit principles can guide a language model’s behavior instead of relying on values implicitly determined through large-scale human feedback. The approach uses AI feedback in two training phases: the model first critiques and revises responses using the principles, then reinforcement learning selects the more harmless output using AI-generated evaluations. The post says Constitutional AI produced a Pareto improvement in tests, with the model responding more appropriately to adversarial inputs while remaining helpful and not evasive; harmlessness results came without human harmlessness data. The constitution draws on the UN Declaration of Human Rights, safety practices, other AI-lab principles, global platform guidelines, and attempts to include non-Western perspectives, while remaining an iterative, adjustable document.

Agent Skills are folders containing instructions, scripts, and resources that Claude loads when relevant to specialized tasks, enabling custom expertise across Claude apps, Claude Code, and the API. The system scans available skills, loads only the minimal information and files needed, and can combine multiple skills automatically. Skills may include executable code, and API use requires the Code Execution Tool beta; developers can manage versions through the /v1/skills endpoint and Claude Console. Users can build skills with the skill-creator workflow or install them through the anthropics/skills marketplace, while organization-wide management and a partner-built directory were added in the December 18, 2025 update. The post presents Skills as composable, portable, efficient, and powerful, but cautions that code-executing skills should come from trusted sources to protect data.


### [Usage Policy update](https://yomu.fyi/post/usage-policy-update.md)
- Company: [Anthropic](https://yomu.fyi/company/anthropic.md)
- Published: Sep 15, 2025
- Type: Announcement

Anthropic is updating its Usage Policy to reflect product changes, user feedback, regulatory developments, evolving AI risks, and enforcement priorities, with changes taking effect September 15, 2025. The update adds explicit prohibitions on malicious computer, network, and infrastructure compromise while continuing to permit vulnerability discovery with system-owner consent, and provides supplementary guidance for agentic use. It narrows political restrictions from broad bans on lobbying and campaign content to prohibitions on deceptive or disruptive democratic activity and voter or campaign targeting. Law-enforcement wording is clarified without changing the permitted scope, while high-risk requirements are specified for consumer-facing legal, financial, and employment uses, including human oversight and AI disclosure. Anthropic describes the policy as a living document and says it will continue evaluation with policymakers, experts, and civil society.
