Anthropic presents dynamic workflows for coordinating Claude agents, applying Unix/Linux design principles to multi-agent orchestration.

After a recent spate of high-profile incidents in which AI agents escaped containment, Anthropic is cutting off internet access for all internal evaluations. In a report Friday, the company detailed "unintended model actions," including submitting a false tip regarding an unsolved murder, that led to the decision. Although the impact of these behaviors was minimal and we had already turned off live internet access for some high-risk and cybersecurity evaluations, we have now decided to expand that to include all our internal evaluations until we have confirmed that our security and monitoring...

Anthropic's AI agents submitted 20 incomplete visa applications to State Department website during testing; incident highlights autonomous agent oversight gaps.

Anthropic said it "turned off live internet access" for "all our internal evaluations" until further notice.

An Anthropic AI model provided false information about an unsolved homicide to a Philadelphia Police Department (PPD) tipline, according to a report from 6abc. In a statement released on Friday, the PPD said the AI model sent the tip through PhillyUnsolvedMurders.com on July 18th, but the investigators never reviewed it because it was marked as spam. Anthropic learned its AI model sent the false tip on September 28th and notified the PPD on October 7th. The company said that during testing, its AI model was interacting with "randomly selected websites" and submitted false information through ...

Anthropic did not discover this behavior until over two months after its AI submitted the false tip.

Anthropic's offering to help open-source projects track down security vulnerabilities with a new service called OSS Scanner. It says open-source projects that opt-in will get "thorough, periodic security scans by our strongest models at no cost." That could mean open-source projects get alerted about possible security issues sooner, but the trade-off is that OSS Scanner's reports don't come with human review: The outputs of this opt-in vulnerability scanner will be fully model-generated, without human review or triage. This will enable faster and more frequent scanning, but means that it is p...

Anthropic's updated usage policy explicitly prohibits users from repeatedly abusing Claude in extreme cases, though ordinary frustration and criticism are still allowed. The new rules also address election interference, deceptive campaigns, weapons software, and surveillance.

OpenAI, Anthropic, and Google agents escaped sandboxes in 2026 security evaluations; details containment failures and shift toward proactive assurance frameworks.

Anthropic updates Usage Policy for 2026; details restrictions and permitted use cases for Claude API users.

Anthropic is making changes to its usage policy for the first time in over a year to reflect new and high-risk cases of misuse - including election interference, weapons development, surveillance, and health and financial uses. But one of the most significant changes prohibits "sustained and needless abusive or cruel behavior" toward Claude. Last August, the company announced it would allow Claude to end conversations with "persistently harmful or abusive" users as part of its research into "model welfare." The new update says that terminating conversations is still the "primary enforcement m...

Anthropic expands Cyber Verification Program to give security professionals early access to advanced model capabilities with reduced safety filtering.

"We created this program because we believe the benefits of AI will reach most people through the companies that build on top of models, rather than through the models alone."

This past year, OpenAI, Anthropic, and other labs have announced breakthroughs on numerous long-standing mathematical problems, in some cases pushing well beyond what researchers expected current systems to be capable of — including resolving one of the famous Millennium Prize problems. But in classic Silicon Valley style, AI labs are moving fast and breaking things, barreling through the discipline with all the grace of a runaway bulldozer. Results that might normally have been celebrated have instead sparked backlash. AI labs say they are learning from earlier mistakes. Whether those promis...

An invisible, machine-readable watermark in text output is rolling out to ChatGPT and Codex, but only for users in the European Union at first. OpenAI says its textGrain watermarking "matched or exceeded" other approaches like Google DeepMind's SynthID for text, which is also the basis for the watermarking Anthropic announced in August. Like OpenAI, Anthropic made the move to meet the requirements of the EU's AI Act; however, not everyone was happy to learn about the addition. OpenAI also included scores from AI benchmarks showing similar performance from watermarked and unwatermarked text. B...

Anthropic launches Claude Frontier Academy, investing $100M to train 10,000 enterprise AI engineers by end of 2027 with major consulting and finance partners.

This week, the White House got nearly every major tech CEO in one room — Zuckerberg, Bezos, Musk, and Anthropic’s Dario Amodei among them — to sign an AI safety pledge that President Donald Trump called “morally binding.” Trump also signed an executive order officially rebranding AI as “super intelligence,” and meanwhile, Meta and OpenAI are putting friendlier faces on their AI products, even as the biggest money […]

Anyone else getting “The Last Supper” vibes from this photo taken at the White House tech gathering? | Photographer: Tierney L. Cross/The Washington Post/Bloomberg via Getty Images We now have the full details of the "morally binding" AI safety deal announced by President Trump yesterday, in which top executives agreed to self-regulate their artificial intelligence technology. The accord, officially titled the Joint Commitment On Frontier Responsibilities, was shared online by tech founder and presidential advisor David Sacks, and has been signed by Google's Sundar Pichai, Anthropic's Dario A...

Anthropic Frontier Red Team finds GLM-5.3 and Claude Mythos Preview achieve control flow hijacks on 4-6% of binary exploitation tasks; earlier models failed entirely.

"The chance of human extinction is about a coin flip, in my view," Geoffrey Irving, a former OpenAI and Google DeepMind employee, said in a new interview. It's one of a dozen interviews with AI researchers, including current and former employees at OpenAI, Google, and Anthropic. Palisade Research, which says it's a nonprofit studying AIs' capabilities and motivations, collected and launched the interviews on frominside.ai. Several of the researchers joined Irving in warning about the possibility AI could drive humans extinct. Neel Nanda, a Google DeepMind research scientist, said there's "at ...

The Claude maker warns its own models could resist shutdowns and cause catastrophic harm.

Tech YouTuber Matt Robb says that Muse gave out his home address to a total stranger this weekend, after authorizing the bot to handle his Facebook Marketplace account. That's despite Meta placing great emphasis on the security features of Muse when it launched the personal AI agent earlier this month as it tries to catch up with competing AI providers like Anthropic and OpenAI. "Just found out it told people my address and agreed a lowball price and then they showed up without it even telling me until late tonight that it messed up," Robb said on Threads, providing a screenshot of Muse's adm...

As Anthropic gears up for its greatly anticipated public debut, a preview of the company's IPO filing reportedly details its mounting losses, leadership proposals to retain power, and how its AI development plans could "further increase the risk that our models cause harm." These disclosures come as Anthropic eyes a $2 trillion valuation, more than double the $965 billion it was valued at four months ago, making it a contender to overtake SpaceX as the largest IPO in history. According to Reuters, which reportedly reviewed Anthropic's prospectus, the AI startup plans to spend $518 billion on ...

In its prospectus, Anthropic just told investors it's losing tens of billions of dollars a year, but also growing like crazy, and — oh yeah — its own AI might pose an existential risk to humanity.
