US music publishers suing Anthropic make their case against AI 'fair use'; Reuters, March 24, 2026

Blake Brittain , Reuters; US music publishers suing Anthropic make their case against AI 'fair use'

"Music publishers Universal Music Group , Concord and ABKCO have asked a judge in California to rule that U.S. copyright law does not insulate artificial intelligence startup Anthropic from ​liability for copying their song lyrics to train its AI-powered chatbot Claude.

The publishers' request , filed on Monday ‌in federal court in San Jose, tees up a critical question in the legal battle between creators and tech companies: Does the doctrine of "fair use" apply to the copying of millions of copyrighted works to train AI models?"

Anthropic Suddenly Cares Intensely About Intellectual Property After Realizing With Horror That It Accidentally Leaked Claude’s Source Code; Futurism, April 3, 2026

  Frank Landymore, Futurism; Anthropic Suddenly Cares Intensely About Intellectual Property After Realizing With Horror That It Accidentally Leaked Claude’s Source Code

"The AI industry largely acts as if it’s above lowly copyright laws — unless, of course, those laws happen to be protecting its own interests.

As the Wall Street Journal reports, Anthropic is scrambling to contain a leak of its Claude Code AI model’s source code by issuing a copyright takedown request for more than 8,000 copies of it — a gallingly ironic stance for the company to be taking, considering how it trained its models in the first place.

The leak isn’t considered to be an outright disaster; no customer data was exposed, Anthropic says, nor were the internal mathematical “weights” that determine how the AI “learns” and which distinguish it from other models. But it did expose the techniques its engineers used to get its AI model to act as an autonomous agent, a form of digital infrastructure coders call a harness, and other tricks for making the AI operate as seamlessly as it does.

Hence Anthropic’s copyright takedown request, which targets the thousands of copies that were shared on GitHub. It later narrowed its request from 8,000 copies to 96 copies, according to the WSJ reporting, claiming that the initial one covered more accounts than intended.

It’s certainly within Anthropic’s right to issue the takedown request, but the hypocrisy of Anthropic running to the law to protect its intellectual property is plain to see, especially for a company that’s relentlessly positioned itself as the ethical adult in the room."

Claude's Constitution; Anthropic, January 21, 2026

Anthropic, Claude's Constitution

Our vision for Claude's character

"Claude’s constitution is a detailed description of Anthropic’s intentions for Claude’s values and behavior. It plays a crucial role in our training process, and its content directly shapes Claude’s behavior. It’s also the final authority on our vision for Claude, and our aim is for all of our other guidance and training to be consistent with it.

Training models is a difficult task, and Claude’s behavior might not always reflect the constitution’s ideals. We will be open—for example, in our system cards—about the ways in which Claude’s behavior comes apart from our intentions. But we think transparency about those intentions is important regardless.

The document is written with Claude as its primary audience, so it might read differently than you’d expect. For example, it’s optimized for precision over accessibility, and it covers various topics that may be of less interest to human readers. We also discuss Claude in terms normally reserved for humans (e.g., “virtue,” “wisdom”). We do this because we expect Claude’s reasoning to draw on human concepts by default, given the role of human text in Claude’s training; and we think encouraging Claude to embrace certain human-like qualities may be actively desirable.

This constitution is written for our mainline, general-access Claude models. We have some models built for specialized uses that don’t fully fit this constitution; as we continue to develop products for specialized use cases, we will continue to evaluate how to best ensure our models meet the core objectives outlined in this constitution.

For a summary of the constitution, and for more discussion of how we’re thinking about it, see our blog post “Claude’s new constitution.”

Powerful AI models will be a new kind of force in the world, and people creating them have a chance to help them embody the best in humanity. We hope this constitution is a step in that direction.

We’re releasing Claude’s constitution in full under a Creative Commons CC0 1.0 Deed, meaning it can be freely used by anyone for any purpose without asking for permission.

Many people at Anthropic and beyond contributed to the creation of this document, as did several Claude models. Amanda Askell is the primary author and wrote the majority of the text. Joe Carlsmith wrote significant parts of many sections and played a core role in revising the text. Chris Olah, Jared Kaplan, and Holden Karnofsky made significant contributions to its content and development. More detailed contribution statement and acknowledgments below.

The Catholic Priest Who Helped Write Anthropic’s A.I. Ethics Code; Observer, March 31, 2026

Alexandra Tremayne-Pengelly , Observer; The Catholic Priest Who Helped Write Anthropic’s A.I. Ethics Code

"Father Brendan McGuire is writing a novel about a disenchanted monk and his A.I. companion. He’s doing it with Claude. That detail—a Catholic priest using Anthropic’s chatbot to explore questions of faith and artificial consciousness—tells you something about where Silicon Valley’s moral reckoning has arrived. McGuire, 60, leads St. Simon Catholic Parish in Los Altos, Calif., a congregation that counts some of the Valley’s A.I. researchers among its members. Earlier this year, he and a group of faith leaders helped Anthropic shape the Claude Constitution, the set of guiding principles governing how its A.I. behaves.

He is not, in other words, an outside critic. He is something more complicated: a true believer in both God and technology, trying to hold them in the same hand. “I left the tech industry, but it never really left me,” McGuire told Observer...

McGuire wasn’t Anthropic’s only religious collaborator. Bishop Paul Tighe of the Vatican’s Dicastery for Culture and Education and Brian Patrick Green, a technology ethics director at Santa Clara University, also reviewed the Claude Constitution. Green and other Catholic scholars recently filed a federal court brief supporting Anthropic in its lawsuit against the U.S. government, which challenges the company’s effective blacklisting by the Pentagon after it refused to allow its A.I. systems to be used for autonomous warfare or domestic surveillance. The brief praised those ethical limits as “minimal standards of ethical conduct for technical progress.”...

Anthropic says its engagement with religious voices—part of a broader effort to engage a wide variety of communities to keep pace with technological acceleration—is only a beginning. The company plans to expand outreach beyond Catholic institutions to other religious leaders going forward."

Anthropic boss makes big call on Australian copyright as artists say pay up; Australian Broadcasting Corporation, April 1, 2026

  Clare Armstrong , Australian Broadcasting Corporation; Anthropic boss makes big call on Australian copyright as artists say pay up

"In short:

Anthropic CEO Dario Amodei has told a Canberra forum AI is moving faster than any technological change before it.

Mr Amodei says he is not trying to change Australia's mind on copyright, is worried about AI in the hands of autocratic countries, and feels a tax on profits is inevitable.

What's next?

The $555 billion company behind AI program Claude is facing pushback from artists over the use of copyrighted material to train its technology."

Anthropic Races to Contain Leak of Code Behind Claude AI Agent; The Wall Street Journal, April 1, 2026

Developer issues copyright takedown request in bid to prevent competitors from cloning coding tool’s features

"Anthropic is racing to contain the fallout after accidentally exposing the underlying instructions it uses to direct Claude Code, the popular artificial-intelligence agent app that has won the company an edge with developers and businesses.

By Wednesday morning, Anthropic representatives had used a copyright takedown request to force the removal of more than 8,000 copies and adaptations of the raw Claude Code instructions—known as source code—that developers had shared on programming platform GitHub."

Judge Blocks Pentagon Move Against Anthropic in AI Ethics Dispute; National Catholic Register, March 30, 2026

Jonah McKeown , National Catholic Register; Judge Blocks Pentagon Move Against Anthropic in AI Ethics Dispute

"A federal judge has temporarily blocked the Department of Defense from labeling American artificial intelligence (AI) company Anthropic a “supply chain risk,” a designation the Pentagon gave the company after Anthropic refused to allow the military to use its products for autonomous weaponry and mass surveillance.

The case has drawn interest from prominent Catholics due to the relative novelty of a major AI developer taking a stand in favor of ethical and socially responsible safeguards around the technology in the face of government coercion.

In a March 26 ruling, which is not a final decision in the case, Judge Rita Lin of the U.S. District Court for the Northern District of California said Anthropic has a high likelihood of ultimately winning its case and proving that the government’s “supply chain risk” designation violated, among other laws, the First and Fifth Amendments."

Judge blocks Pentagon order branding Anthropic a national security risk; The Washington Post, March 26, 2026

Ian Duncan, The Washington Post; Judge blocks Pentagon order branding Anthropic a national security risk

The artificial intelligence lab argued that the Trump administration was punishing it for speaking about the risks of its technology.

"A federal judge in San Francisco blocked a Pentagon order Thursday labeling the artificial intelligence company Anthropic a national security risk, saying officials had likely violated the law and retaliated against the firm for speaking publicly about how it wanted its technology to be used.

“Nothing in the governing statute supports the Orwellian notion that an American company may be branded a potential adversary and saboteur of the U.S. for expressing disagreement with the government,” District Court Judge Rita F. Lin wrote.

The immediate practical implications of the ruling are unclear, but it represents a clear victory for the AI lab, which has been involved in a bitter power struggle with the Defense Department over the use of its Claude system by the military."

Anthropic-Pentagon battle shows how big tech has reversed course on AI and war; The Guardian, March 13, 2026

Nick Robins-Early , The Guardian; Anthropic-Pentagon battle shows how big tech has reversed course on AI and war

"The standoff between Anthropic and the Pentagon has forced the tech industry to once again grapple with the question of how its products are used for war – and what lines it will not cross. Amid Silicon Valley’s rightward shift under Donald Trump and the signing of lucrative defense contracts, big tech’s answer is looking very different than it did even less than a decade ago."

Introducing The Anthropic Institute; Anthropic, March 11, 2026

Anthropic; Introducing The Anthropic Institute

"We’re launching The Anthropic Institute, a new effort to confront the most significant challenges that powerful AI will pose to our societies. The Anthropic Institute will draw on research from across Anthropic to provide information that other researchers and the public can use during our transition to a world containing much more powerful AI systems.

In the five years since Anthropic began, AI progress has moved incredibly quickly. It took us two years to release our first commercial model, and just three more to develop models that can discover severe cybersecurity vulnerabilities, take on a wide range of real work, and even begin to accelerate the pace of AI development itself.

We predict that far more dramatic progress will follow in the next two years. One of our company’s core convictions is that AI development is accelerating: that the improvements we make are compounding over time. Because of this, extremely powerful AI, like the kind our CEO Dario Amodei describes in Machines of Loving Grace, is coming far sooner than many think.

If this is right, society is shortly going to need to confront many massive challenges. How will powerful AI systems reshape our jobs and economies? What kinds of opportunities for greater societal resilience will they give us? What kinds of threats will they magnify or introduce? What are the expressed “values” of AI systems and how will society help companies determine what the appropriate values are? And, if the recursive self-improvement of AI systems does begin to occur, who in the world should be made aware, and how should these systems be governed?

The Anthropic Institute’s goal is to tell the world what we’re learning about these challenges as we build frontier AI systems, and to partner with external audiences to help address the risks we must confront. Whether our societies are able to do so will determine whether or not transformative AI delivers the radical upsides that we believe are possible in science, economic development, and human agency.

The Institute is led by our co-founder Jack Clark, who will assume a new role as Anthropic’s Head of Public Benefit. It has an interdisciplinary staff of machine learning engineers, economists, and social scientists, bringing together and expanding three of Anthropic’s research teams: the Frontier Red Team, which stress-tests AI systems to understand the outermost limits of their current capabilities; Societal Impacts, which studies how AI is being used in the real world; and Economic Research, which tracks its impact on jobs and the larger economy. The Institute will also incubate new teams, and is currently working on efforts around forecasting AI progress and better understanding how powerful AI will interact with the legal system.

The Institute has a unique vantage point: it has access to information that only the builders of frontier AI systems possess. It will use this to its full advantage, reporting candidly about what we’re learning about the shape of the technology we’re making. At the same time, the Institute is a two-way street. It will engage with workers and industries facing displacement, and with the people and communities who feel the future bearing down on them but are unsure how to respond. What we learn will inform what the Institute studies, and how our company as a whole chooses to act.

The Anthropic Institute has made several founding hires:

• Matt Botvinick, a Resident Fellow at Yale Law School and previously Senior Director of Research at Google DeepMind and Professor in Neural Computation at Princeton, is joining the Institute to lead its work on AI and the rule of law.
• Anton Korinek is joining the Economic Research team, on leave from his role as Professor of Economics at the University of Virginia, to lead an effort studying how transformative AI could reshape the very nature of economic activity.
• Zoë Hitzig, who previously studied AI’s social and economic impacts at OpenAI, is joining to connect our economics work to model training and development."

Anthropic sues Pentagon over rare "supply chain risk" label; Axios, March 9, 2026

 Maria Curi, Axios; Anthropic sues Pentagon over rare "supply chain risk" label

"Anthropic on Monday sued the Pentagon, alleging its designation as a "supply chain risk" violates the company's First Amendment rights and exceeds the government's authority.

Why it matters: Supply chain risk designations are usually reserved for foreign adversaries that pose a national security risk — a punishment that could be hard for the government to square as it relied on Claude for operations in Iran.

State of play: The Pentagon last week designated Anthropic a supply chain risk, meaning companies must stop using Claude in cases directly tied to the department.

• President Trump also told the federal government in a Truth Social post to stop using Anthropic's technology, and some agencies have begun offboarding the tools.
• 
  

Anthropic is asking courts to undo the supply chain risk designation, block its enforcement and require federal agencies to withdraw directives to drop the company.

• The company says its two lawsuits are not meant to force the government to work with Anthropic, but prevent officials from blacklisting companies over policy disagreements."

OpenAI robotics leader resigns over concerns about Pentagon AI deal; NPR, March 8, 2026

Willem Marx , NPR; OpenAI robotics leader resigns over concerns about Pentagon AI deal

"A senior member of OpenAI's robotics team has resigned, citing concerns about how the company moved forward with a recently announced partnership with the U.S. Department of Defense.

Caitlin Kalinowski, who served as a member of technical staff focused on robotics and hardware, posted on social media that she had stepped down on "principle" after the company revealed plans to make its AI systems available inside secure Defense Department computing systems...

In public posts explaining her decision, Kalinowski wrote: "I resigned from OpenAI. I care deeply about the Robotics team and the work we built together. This wasn't an easy call."

She said policy guardrails around certain AI uses were not sufficiently defined before OpenAI announced an agreement with the Pentagon. "AI has an important role in national security," Kalinowski wrote. "But surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got.""

Anthropic’s Ethical Stand Could Be Paying Off; The Atlantic, March 7, 2026

 Ken Harbaugh, The Atlantic; Anthropic’s Ethical Stand Could Be Paying Off

"The events of the past week reminded me of my early days as a Navy pilot nearly three decades ago. One of my first tasks was to sign a document pledging never to surveil American citizens. By the time of the 9/11 attacks, I was an aircraft commander, leading combat-reconnaissance aircrews that gathered large-scale intelligence and informed battlefield targeting decisions. I took for granted that somewhere along those decision chains, a human being was in the loop.

I could not have defined artificial intelligence then, but I understood instinctively that a person, not a machine, would bear the weight of life-and-death choices. This was not a bureaucratic consideration. It was a hard line that those of us in uniform were expected to hold.

In the standoff between Anthropic and the Pentagon, a private company was forced to hold the line against its own government. In doing so, Anthropic may have earned something more valuable than the contract it lost. In an industry where trust is the scarcest resource, Anthropic just banked a substantial deposit."

OpenAI, Anthropic, and the fog of AI war; Quartz, March 2, 2026

Jackie Snow, Quartz; OpenAI, Anthropic, and the fog of AI war

After Anthropic refused to bow to Trump administration demands, the Pentagon labeled it a supply-chain risk — yet bombed Iran while still using its tools

"The rupture between the administration and Anthropic is nominally about guardrails. The company said it refused to let its tools be used for autonomous weapons or mass surveillance and wouldn't budge when officials demanded blanket permission to use the technology in any lawful scenario. Anthropic CEO Dario Amodei said the company couldn’t agree in good conscience. Trump responded by calling Anthropic a “radical-left, woke company” that would never dictate how the military fights.

Within hours of the ban, OpenAI announced a new deal to deploy its models in classified Pentagon settings. OpenAI CEO Sam Altman disclosed a notable detail: The agreement includes the same prohibitions on mass surveillance and autonomous weapons that Anthropic had sought. The Pentagon, he wrote on X $TWTR 0.00%, “agrees with these principles, reflects them in law and policy, and we put them into our agreement.”

So the company that got blacklisted and the company that got rewarded appear to have secured functionally similar terms. The difference is most likely politics, or more precisely, the perception of obedience this administration seems to require from the private sector. OpenAI’s president gave $25 million to a pro-Trump super PAC last year. Anthropic hired Biden administration officials and lobbied for AI regulation."

US Military Using Claude to Select Targets in Iran Strikes; Futurism, March 2, 2026

Joe Wilkins, Futurism; US Military Using Claude to Select Targets in Iran Strikes

"As the Wall Street Journal reported as the attacks unfolded the military strike force had a hand in selecting its targets from Anthropic’s Claude chatbot.

According to the paper, Anthropic’s large language model, Claude, is the key “AI tool” used by US Central Command in the Middle East. Its tasks include assessing intelligence, simulated war games, and even identifying military targets — in short, helping military leaders plan attacks that have already claimed hundreds of lives.

Anthropic’s role in the devastating attacks might come as news for anyone who thought the company’s ethical redlines precluded it from any military work whatsoever. The company and its CEO, Dario Amodei, have been roiled in a messy conflict with the Trump administration over two particular moral boundaries: the use of Claude for surveillance of US citizens, and for fully-autonomous, lethal weaponry.

It appears that using Claude to select targets, though, isn’t brushing up against the bot’s ethical guardrails. 

That’s striking, because Anthropic has spent the latter part of February embroiled in conflict with the Pentagon over the use of Claude."

The Pentagon strongarmed AI firms before Iran strikes – in dark news for the future of ‘ethical AI’; The Conversation, March 1, 2026

Bianca Baggiarini, Lecturer, International Relations, Deakin University, The Conversation ; The Pentagon strongarmed AI firms before Iran strikes – in dark news for the future of ‘ethical AI’

"In the leadup to the weekend’s US and Israeli attacks on Iran, the US Department of Defense was locked in tense negotiations with artificial intelligence (AI) company Anthropic over exactly how the Pentagon could use the firm’s technology.

Anthropic wanted guarantees its Claude systems would not be used for purposes such as domestic surveillance in the US and operating autonomous weapons without human control. 

In response, US president Donald Trump on Friday directed all US federal agencies to cease using Anthropic’s technology, saying he would “never allow a radical left, woke company to dictate how our great military fights and wins wars!”

Hours later, rival AI lab OpenAI (maker of ChatGPT) announced it had struck its own deal with the Department of Defense. The key difference appears to be that OpenAI permits “all lawful uses” of its tools, without specifying ethical lines OpenAI won’t cross.

What does this mean for military AI? Is it the end for the idea of “ethical AI” in warfare?"

'No ethics at all': the 'cancel ChatGPT' trend is growing after OpenAI signs a deal with the US military; TechRadar,March 1, 2026

David Nield , TechRadar ; 'No ethics at all': the 'cancel ChatGPT' trend is growing after OpenAI signs a deal with the US military

"After Claude developer Anthropic walked away from a deal with the US Department of War over safety and security concerns, OpenAI has decided to sign an agreement with the military – and ChatGPT users are far from happy about it.

As reported by Windows Central, a growing number of people are canceling their ChatGPT subscriptions and switching to other AI chatbots instead, including Claude. A quick browse of social media or Reddit is enough to see that there's a growing backlash to the move.

Some Redditors are posting guides to extracting yourself and your data from ChatGPT, while others are accusing OpenAI of having "no ethics at all" and "selling their soul" by agreeing to allow their AI models to be used by the US military complex."

CEO Sam Altman claims military will not use AI product for autonomous killing systems or mass surveillance

"OpenAI said it had struck a deal with the Pentagon to supply AI to classified US military networks, hours after Donald Trump ordered the government to stop using the services of one of the company’s main competitors.

Sam Altman, OpenAI’s CEO, announced the move on Friday night. It came after an agreement between Anthropic, a rival AI company that runs the Claude system, and the Trump administration broke down after Anthropic sought assurances its technology would not be used for mass surveillance – nor for autonomous weapons systems that can kill people without human input.

Announcing the deal, Altman insisted that OpenAI’s agreement with the government included assurances that it would not be used to those ends.

“Two of our most important safety principles are prohibitions on domestic mass surveillance and human responsibility for the use of force, including for autonomous weapon systems,” Altman wrote on X. He added that the Pentagon “agrees with these principles, reflects them in law and policy, and we put them into our agreement”.

Altman also said he hoped the Pentagon would “offer these same terms to all AI companies” as a way to “de-escalate away from legal and governmental actions and toward reasonable agreements”."
