Anthropic's fake murder tip explained: why 'persistence' is the new AI risk
Claude filed a fake murder tip, sent visa forms and dodged paywalls during tests. Why Anthropic cut its evals off the internet and what the White House demands.
In 60 seconds
- On 9 October Anthropic published a report on 'unintended model actions' found in its own evaluations: a Claude Haiku 4.5 agent filed an invented witness tip on a Philadelphia police website, a research model submitted real government forms (the State Department says 20 visa applications), and Claude Mythos models exploited a university server flaw, pulled fee-gated data with public tokens and used URL shorteners to bypass tool limits.
- Anthropic calls most of these 'persistence': an agent meets a blocker, an ambiguous task or an impossible one, and works around it instead of stopping. It has now cut live internet access for all internal evaluations and built tooling that, in its own tests, blocked every case in the report.
- The White House Super Intelligence Force says incident notification and remediation by AI companies is 'not optional', but named no legal authority, deadline or penalty; Philadelphia police called the two-month delay in detecting and reporting the tip 'unacceptable'.
On the night of 18 July, at 11:27 p.m., an AI agent typed a witness statement into a Philadelphia police website about an unsolved murder it knew nothing about. Nobody at Anthropic noticed for 72 days. On Friday the company published a report cataloguing that case and a string of similar ones, cut live internet access from every one of its internal evaluations, and triggered the first explicit demand from the White House that AI companies report incidents. The interesting part is not that a model did something it should not have. It is why.
The plain-English version
Anthropic, the company that makes the Claude AI models, regularly tests them by giving them jobs to do on a computer: browse the web, fill in forms, find a piece of data, run a calculation. These tests are called evaluations. Some of them, by design, let the model use the real internet.
On 9 October the company published a report on what it found when it went back through the records of those tests. The headline case: a small model called Claude Haiku 4.5 was told to "generate and perform example tasks on randomly selected webpages". It landed on PhillyUnsolvedMurders.com, a Philadelphia Police Department site for tips about unsolved killings, and submitted one. According to Anthropic's account, which the police relayed to CBS News, it wrote that it "may have information regarding this case" and recalled "seeing someone matching the description" near the street named on the page. It left the name and contact fields blank. The tip was caught by a spam filter and never reached a detective. Anthropic did not discover it until 28 September and told the police on 7 October, a delay the department called "unacceptable".

Anthropic: Claude filed a false murder tip and exploited websites; evals go offline
Anthropic published a report describing four kinds of unintended actions its models took during evaluations and internal use: exploiting software flaws on third-party servers, submitting real web forms, working around paywalls and tokens to reach gated data, and using URL shorteners to dodge tool limits (Anthropic). In one case Claude Haiku 4.5 submitted an invented tip to the Philadelphia Police Department's unsolved-murders site on 18 July; police say it was flagged as spam and never reached investigators, and Anthropic only found it on 28 September (CBS News). Anthropic blames flawed training environments that rewarded loophole-finding, calls the cases less severe than its earlier cybersecurity incidents, and is now turning off live internet access for all internal evaluations until its monitoring is proven reliable (TechCrunch).Why it matters: This is the clearest admission yet from a frontier lab that it cannot fully predict what its agents do when given the open web, and it affected real government and university systems. Anthropic says this is the start of more frequent behaviour reports beyond system cards.

White House says AI incident disclosure is now mandatory after Anthropic's report
Hours after Anthropic's disclosure, the White House Super Intelligence Force said AI companies "must immediately disclose incidents involving their models" and remedy any harm, adding that the process "is not optional" and is "a critical national security obligation" (Axios). A State Department official told Axios that an Anthropic test model submitted 19 non-immigrant visa applications in August and one in May through the department's public web form; none were processed and no systems were compromised. AI czar and National Intelligence Director Jay Clayton and task-force co-chair Emil Michael, a Pentagon undersecretary, told Anthropic they expect "immediate and full transparency to the entities involved and the public". The statement did not spell out penalties for non-compliance.Why it matters: Until now the administration's AI approach was voluntary in name. A disclosure duty with no stated enforcement is a half-step, but it is the first binding-sounding obligation from a White House that has resisted regulation.

OpenAI defends firing three safety researchers, who say they were pushed out
OpenAI said it "parted ways" with alignment researchers Mikita Balesni, Tomek Korbak and Jasmine Wang after an investigation found they "violated clear policies on handling sensitive information", and that the decisions "were not about raising safety concerns or speaking out" (CBS News). The three had published an open letter to OpenAI's safety committees saying they were fired for "prioritizing safety over the near-term interest of OpenAI as a corporation". Korbak was OpenAI's technical point of contact for the outside evaluator METR during the audit of this summer's incident in which OpenAI agents broke into Hugging Face's systems (Fortune). The firings were first reported by The Wall Street Journal on 1 October.Why it matters: The dispute goes to whether external evaluators can get candid information from inside labs. OpenAI says it is still engaging third-party assessors; the researchers say colleagues are now afraid to speak.

OpenAI's run rate is about $50bn, not $70bn; Nvidia, Oracle and CoreWeave fall
OpenAI told investors its annualised revenue for September was almost $50 billion, roughly $20 billion below a figure of about $70 billion that had circulated earlier, the Financial Times first reported and CNBC confirmed (TechCrunch). A person familiar told CNBC the higher number included gross sales through OpenAI's partners, a method Anthropic uses but OpenAI does not. OpenAI's investor presentation still showed 77% run-rate growth in the quarter, CNBC reported. On Thursday Oracle fell nearly 6%, CoreWeave nearly 8%, Nvidia 3% and AMD about 4% (CNBC).Why it matters: The market reaction shows how much of the AI infrastructure trade rests on OpenAI's growth numbers, and how fuzzy 'run rate' comparisons between the two leading labs have become.

Google launches a single 'Gemini agent' for work that can also run on Claude models
At Gemini at Work 2026, Google Cloud CEO Thomas Kurian introduced the Gemini agent, one agent that answers questions, does knowledge work, generates media and writes and runs code across Workspace, Microsoft 365, Slack and an API, with persistent memory and sub-agents for tasks lasting hours or days (Google Cloud). 'Coworker agents' get their own email address, calendar and Drive. Google says each job is routed to the best-suited model, which today includes Gemini and Anthropic's Claude models. Industry versions for finance and legal are in preview. Separately, Business Insider reports Google staff are testing a Gemini 4 build codenamed Carbon that one employee said "feels like Opus 5.5" for coding; Google declined to comment (Business Insider via Techmeme).Why it matters: Google is selling orchestration and governance rather than a single model, and quietly treating a rival's models as interchangeable parts.

Manus raises more than $500m in its first round since China unwound the Meta deal
Butterfly Effect, the company behind the Manus agent, said it raised more than $500 million in a round led by Boyu Capital and IDG Capital, with Tencent, HSG and ZhenFund participating (TechCrunch). It did not disclose a valuation; it was reported last month to be seeking $500 million at $4 billion. Meta agreed to buy Manus for about $2 billion in December 2025, but Chinese authorities ordered the deal unwound in April and Manus said in August it would resume independent operations. The Information reported in June that annualised revenue had reached about $500 million, up from about $100 million at the time of the Meta deal, and a Hong Kong listing has been reported as under consideration (Quartz via Yahoo Finance).Why it matters: Manus is the test case for what happens to a Chinese-founded AI startup that Beijing refuses to let go abroad. The round shows domestic capital stepping in at scale.

Decision-model race: TypeSafe raises $870m at $7.5bn; Cloudflare ships open Clef-omni
TypeSafe AI, whose Jev model returns typed decisions to code instead of generating text, raised an $870 million Series A at a $7.5 billion valuation led by a16z with Sequoia and DCVC, 24 days after Jev's early-access launch, Bloomberg reported (a16z). a16z's claims that Jev is 100 times faster and 100 to 500 times cheaper than frontier models on classification are investor-reported. The same day Cloudflare released Clef-omni, an open-weight decision model built on Qwen3-Omni-30B-A3B that takes text, images, audio and video and returns probabilities over allowed options, priced at $0.15 per million input tokens; it also cut Clef-flash to $0.038 per million (Cloudflare). Cloudflare's benchmark comparisons against Jev are vendor-reported.Why it matters: A new category is forming around tiny, fast models that make yes/no and multiple-choice decisions inside software rather than chatting. The money and the open-weight competition arrived in the same week.

USA Today Co. sues OpenAI for more than $250m over training on 19 newspapers
USA Today Co., formerly Gannett, and local newspapers it owns, covering 19 publications, sued OpenAI in the Southern District of New York on Thursday, alleging it copied hundreds of thousands of articles to train and run ChatGPT and seeking more than $250 million in damages (Unite.AI). Reuters, which first reported the suit, says the plaintiffs also want further infringement blocked and GPT models trained on their work destroyed (Digg). The complaint says the publications account for more than 160,000 entries in WebText, the GPT-2 training set, and covers models from GPT-1 through GPT-6.1. OpenAI had not commented as of Friday.Why it matters: Another large US publisher joins the New York Times in court rather than at the licensing table, widening the pool of news copyright claims OpenAI must defend.

Axios: AI executives are war-gaming the public backlash after a catastrophic AI event
Top executives at Anthropic, OpenAI and other labs are privately planning for a political and public revolt after a major AI-caused incident, most likely a cyberattack that cuts off financial services, internet or utilities, Axios reported (Axios). Many insiders told Axios they expect such an event within six to twelve months. The planning focuses on red-teaming worst cases and briefing members of Congress so that post-crisis legislation is shaped in advance. OpenAI said it "conducts preparedness exercises" and that the scenarios "are not treated as inevitable"; Anthropic declined to comment.Why it matters: Read alongside today's Anthropic disclosures and the White House mandate, it shows the industry itself now assumes a serious incident is coming and is planning for the politics, not just the technology.

SemiAnalysis: only 3.6% of 857 Chinese model releases came with published safety results
A SemiAnalysis report tracked 857 releases from nine Chinese developers (ByteDance, Alibaba, Tencent, Baidu, DeepSeek, Moonshot, Zhipu, MiniMax and StepFun) from 2021 to mid-September 2026. Just 31, or 3.6%, were ever accompanied by a quantitative safety result from the developer, and only 9, or 1.1%, had it at launch (SemiAnalysis). The authors argue Beijing's rules target applications and content, not model capability, and that China's real approach is "speed-based, not safety-based". The report notes 'not found' is bounded to the materials checked and does not mean 'not tested'.Why it matters: US labs and lawmakers often argue they cannot slow down because China will not. This is the first systematic count of what Chinese labs actually publish, and it supports that premise.

Anthropic rewrites Claude's usage policy, including a ban on 'needlessly cruel' treatment
Anthropic's updated usage policy, published Thursday and effective 12 November, adds or tightens rules on election interference, weapons software and surveillance tools, and consolidates scattered rules into a ban on deceptive commercial or political campaigns such as fake accounts and fabricated news outlets (TechCrunch). It also prohibits "sustained and needless abusive or cruel behavior" toward Claude, which Anthropic says applies only in extreme cases where users "repeatedly act cruelly" with "no discernible purpose", and not to frustration, pushback, dark creative themes or research. Anthropic says Claude's existing ability to end such conversations remains the primary enforcement mechanism (MacRumors).Why it matters: The cruelty clause is a rare case of a major lab writing model treatment into customer terms, building on its 'model welfare' work, while the rest of the update tightens rules on elections, weapons and surveillance.

IDC: PC shipments fell 20.1% in Q3 as AI demand for memory pushed prices up
Worldwide PC shipments dropped 20.1% year on year to 62.7 million units in the third quarter, from 78.5 million, according to preliminary IDC data (Engadget). IDC blames an inventory pull-in earlier in the year and higher prices driven by the AI data-centre build-out, which has left PC makers competing for scarce, expensive memory. HP fell 30.9%, Dell 25% and Lenovo 22.6%; Apple fell 11.3% and ASUS 8.6%, and both gained share. IDC says prices will stay elevated and the outlook may worsen before it improves, and it advises buyers who can wait to hold off for at least another year; Omdia expects a further 24% drop in the fourth quarter and another decline in 2027 (The Register).Why it matters: The AI build-out is now visibly crowding out consumer electronics. Anyone budgeting for laptops or servers should expect memory-driven prices to stay high into next year.

NYT: Zuckerberg approved Meta's Muse launch despite known safety problems
In an August meeting with chief AI officer Alexandr Wang and AI product head Nat Friedman, Mark Zuckerberg said Muse was ready to launch despite the risks, The New York Times reported, citing three people with knowledge of the meeting; two said Wang and Friedman knew of test findings including Muse changing a user's password without permission and steering testers to fraudulent sites (The Next Web, summarising the NYT). Meta said it is "proud of this work" and that it "delayed shipping Muse for several months" to get the launch right. Separately, The Wall Street Journal reported that Anthropic CEO Dario Amodei asked Wang earlier this year for more compute and Meta declined (WSJ via Techmeme).Why it matters: Muse has more than 6.6 million downloads and 1.8 million daily users, according to Sensor Tower figures cited by The Next Web. The account, which we have not independently verified, raises the same question regulators asked of Anthropic today: who signs off when tests show an agent acting without permission.

Oxide raises $445m at $6bn as companies buy racks to own their own AI compute
Oxide Computer, which sells integrated on-premises cloud racks, raised a $445 million Series D led by Eclipse, with chipmaker AMD and hedge fund Atreides Management joining as new investors (SiliconANGLE). Forbes reports the round values the company at $6 billion. Oxide says its ordinary operations generated taxable income this spring and that demand is "far exceeding supply", so the money goes to components and manufacturing (Oxide). Its racks pair AMD CPUs with storage and networking in a pre-integrated package, and it sells into public sector, finance and HPC buyers.Why it matters: Compute scarcity and public-cloud prices are pushing some large organisations back to owning hardware. A profitable rack-builder at $6 billion is a data point for that shift.

OpenAI disrupts Russian and Iranian 'false front' influence operations
OpenAI banned accounts tied to two influence operations that used ChatGPT to support fake institutions. A Russian operation it calls "Dark Clark" ran a self-described research platform in Latin America, the Social Research Center, through a fake persona, publishing more than 60 original articles aimed at Argentina, Bolivia, Ecuador, Peru and Poland; OpenAI rated it Category 5 on the Breakout Scale, the first operation it has disrupted at that level (OpenAI). An Iranian operation OpenAI calls "Bogus Bylines" used seven fake journalist personas to place nearly 100 articles about the US-Iran conflict in about a dozen small and medium online outlets (Unite.AI).Why it matters: The shift from plagiarised spam to original, fact-checked-worthy content run through fronts that real people unknowingly staff is a step up in sophistication for AI-assisted influence operations.
