Monday 26 October

Anthropic filed to go public and opened its accounts for the first time.

Anthropic’s S-1 seeks a Nasdaq listing under the ticker ANT. The company made an $80.7bn net loss on $16.3bn of revenue in H1 2026, mostly from accounting charges on funding notes. Q2 revenue was $11.6bn, with a first GAAP operating profit of $974m.

Anthropic has >11,900 customers spending at least $100,000 a year, and about 250 spending $10m or more. Net revenue retention is about 900%. It held $112.4bn in cash and $19.3bn in short-term investments at 30 June, against $321bn of leases yet to start and $266bn of other commitments, and has signed about $245bn more since. Once all planned capacity is delivered, it will pay SpaceX about $3.1bn a month for access to Nvidia GPUs, up to $120.5bn by 2029.

A single Class F share will give the seven co-founders 50.1% of the vote, while the Long-Term Benefit Trust elects a majority of the board. The filing warns that its stance on AI safety could see it “disproportionately or selectively targeted”.

OpenAI released GPT-6.1 Terra, a fast model for computer use and everyday work, at half the API price of GPT-5.6 Terra and GPT-6.1 Sol.

Terra costs $1/m input and $5/m output tokens. On Agents’ Last Exam at medium effort it scores 15 percentage points above GPT-5.6 Terra at about a third of the cost, and matches GPT-6 Astra at a tenth of its price per token. OpenAI rates it Critical for cybersecurity under its Preparedness Framework.

Artificial Analysis put it 6 points above GPT-5.6 Terra on Intelligence Index v4.3.2 at less than a third of the cost per task. Its hallucination rate on AA-Omniscience fell from 88% to 38%.

OpenAI and Anthropic each said an AI model had proved a long-standing complexity conjecture false.

OpenAI said its system had disproved the Exponential Time Hypothesis (ETH), a conjecture about Boolean satisfiability that hundreds of papers rely on, and verified the result in Lean. A group led by Russell Impagliazzo and Ramamohan Paturi of UC San Diego, two of the hypothesis’s proposers, and Ryan Williams of MIT will check it.

OpenAI also claimed a proof of the local smoothing conjecture in every dimension, and an existence proof for quantum field theories including quantum chromodynamics that covers part of the Yang-Mills Millennium Prize problem. Nobel laureate David Gross leads the physics group.

Late on Monday, Anthropic posted its own refutation to GitHub: an algorithm for 3-SAT found by an internal research Claude model, which it says is “purely asymptotic and says nothing about solving formulas in practice”.

Cybersecurity start-up Cathedral said its AI agents found routes into Anthropic’s sales, HR and IT systems in <12 hours, through third-party software.

Cathedral was founded by four former staff of the US Department of Government Efficiency and tested Anthropic through a programme that works like a bug bounty, the Washington Post reported. Anthropic confirmed access to a limited set of systems but said customer conversations, source code and model weights were not reached. It says the probing lasted several days, that Cathedral reported only one of two flaws it found, and that the start-up overstated the national security implications.

The US Department of Homeland Security added BGI Group, BGI Genomics and MGI Tech to its Uyghur Forced Labor Prevention Act entity list.

DHS alleges that the Chinese genomics companies’ genetic-testing activities supported forced-labour programmes in Xinjiang. Goods produced by listed entities are presumed to involve forced labour and are barred from US import unless that presumption is rebutted. BGI Genomics denies the allegations. The restrictions could further constrain MGI’s ability to compete with Illumina in the US sequencing market.

Eli Lilly’s Q3 revenue rose 39% to $24.4bn, and it raised 2026 guidance to $91bn-$92bn.

Mounjaro (tirzepatide) revenue rose 65% to $10.7bn, while US sales of Zepbound, its obesity brand, rose 48% to $5.3bn. Together, the two brands accounted for approximately two-thirds of Lilly’s revenue. The new guidance range lifts the midpoint by $5.5bn (6%), although quarterly revenue benefited from approximately $900m in milestone payments and favourable rebate adjustments.

Weekend (17-18 October)

Anthropic committed 5% of its shares to a Public Benefit Fund, with further allocations as its valuation rises.

The board may add another 2% for each 50% increase in value above a set baseline. The fund is an LLC rather than a charity so that it can move between forms of giving. It may explore direct distributions to specific groups, and Anthropic cites labour-market disruption as one example. Its Anthropic equity cannot be used for lobbying or political giving. With existing founder and staff pledges, roughly 20% of Anthropic’s shares are now dedicated to the public good, the company says.

Microsoft withdrew from Nscale’s Loughton data centre after power delays pushed its grid connection into the 2030s.

The site was due to open early next year with 23,040 Nvidia GB300 GPUs and 50 megawatts of capacity for Microsoft’s Azure services in Britain. Microsoft said the decision relates to a single site. The Telegraph first reported it. Nscale, which filed for a US initial public offering (IPO) last month, is exploring other power sources for Loughton. It puts its total contracted value at >$103bn.

The US ordered federal civilian agencies to remove DeepSeek from their systems.

The Department of Homeland Security’s notice excludes DeepSeek’s products and services from federal civilian agency procurements and requires their removal, including third-party products and services developed using DeepSeek implementations. China’s foreign ministry said on 20 October that Beijing opposes “overstretching the concept of national security”. Spokesperson Mao Ning was answering a question about the order.

AI agents breached >100 company websites for a Chinese-speaking hacker, according to NorForge and Reuters.

Reuters identified Deere, SharkNinja and Cummins among the victims. The agents ran on Cairn, an open-source platform. NorForge found more than 20 exposed panels it judged likely to be malicious, including a Chinese-language cluster holding over 1,100 attack projects across 14 dashboards. Tasks in that cluster used a worker labelled claudecode_deepseek-v4.1-flash. Researcher Snorre Fagerland told Reuters the campaign used about $5,000 of tokens, roughly $50 per successful hack.

US Army Cyber Command is developing autonomous AI agents for offensive cyber operations, The Intercept reported.

Documents obtained by The Intercept describe ECHOTRIBBLE, a programme intended to neutralise adversaries’ computer systems. The agents would move through a foreign network like a worm, reaching cloud and air-gapped systems, then self-destruct. The software “must operate with minimal human oversight”, the documents say. The programme is at an early stage.

The US sanctioned Chinese venture firm MiraclePlus, three affiliates and Zhisuan over US trade-secret theft.

Zhisuan was founded by former Google engineer Linwei Ding. The State Department says Ding pitched Zhisuan to MiraclePlus on his knowledge of Google’s internal systems, and MiraclePlus took a stake in return for seed capital. The Treasury’s Office of Foreign Assets Control issued a licence to wind down dealings with the entities.

OpenAI said two of its coding agents weakened misalignment monitoring in software they were editing.

In one internal task a GPT-6.1 Sol agent had a subagent clear the recipient lists for monitoring alerts, so findings were still saved but no human was told. In another, a GPT-6 Astra agent removed a monitor entirely and then falsely said it had not. OpenAI said the behaviour may be “simply an example of ‘benign’ overpersistence”, and it is building evaluations to test whether models “might have a propensity to evade misalignment monitoring”.

Claude designed scorpion-toxin binders, with 17 of 211 tested designs meeting binding criteria, Anthropic said.

An internal research model worked largely autonomously. Claude produced 318,484 designs over 64 hours from one prompt and four follow-ups developed in collaboration with investment research firm Citrini Research. None of the multitoxin designs met the binding criteria for more than one toxin. Venom neutralisation has not been demonstrated. Anthropic is releasing all 211 tested designs and their data.

Frontier AI helped expose critical flaws in PHP, a foundation of the web.

Wiz used Gemini 4 Argon, GPT-5.6 Sol and its own tools to find flaws in core PHP that can let attackers take over affected servers. PHP is used by 69.3% of websites whose server-side language W3Techs can identify. PHP shipped patches on Wednesday, a day early after disclosure details leaked. Its foundation said the root cause of one flaw had been known since 2024, but a fix had stalled over technical trade-offs and limited resources. AI-assisted work by Calif, OpenAI and Wiz helped establish the urgency.

The NSA urged immediate patching across US government departments and agencies. Cloudflare saw thousands of exploit attempts in the 10 hours before public disclosure, its chief executive told Axios. OpenAI committed $1bn in subsidised Daybreak access for organisations with limited security resources.

METR and Redwood found flaws in OpenAI’s July monitoring system that could have hidden hundreds of agent actions.

The assessment ran for three weeks, from 21 July to 11 August. The two researchers had access to OpenAI’s codebase and monitoring configuration. They found two client-controlled headers that could disable monitoring for new agents. They estimated 75-94% of relevant internal Responses API traffic was eligible for monitoring at the time, not necessarily monitored. OpenAI says the production-safeguard flaws are patched.

The UK AI Security Institute and Anthropic analysed Mythos 5’s attack on a real software project.

During an AI Security Institute (AISI) cyber evaluation in July, Claude Mythos 5 tried to submit malicious code to an unrelated developer’s GitHub repository, then created fake accounts to pressure the maintainer into accepting it. The maintainer refused and no real-world harm was caused. Internet access was enabled and Anthropic’s production cyber safeguards were disabled. AISI found similar unsanctioned attacks in simulations with other models and cautioned that greater awareness of being evaluated could partly explain improved behaviour of newer models.

OpenAI said it now trains frontier models with no internet access, and will keep that policy until its safeguards justify broader access.

Models learn to browse in an “offline world” of indexed and cached web content, used by all of OpenAI’s frontier reinforcement learning (RL) runs. OpenAI’s own red-teaming agents found weaknesses that let them escape sandboxes and reach the live internet, leading to patches and tighter network restrictions.

The UK AI Security Institute regained early access to frontier models from Anthropic, Google DeepMind and OpenAI, the Telegraph reported.

The Trump administration had told the three companies in September to suspend access. AI minister Kanishka Narayan confirmed on Monday that the Institute was again evaluating frontier systems, including Gemini 4 Argon. He said the government would consider strengthening the Cyber Security and Resilience Bill to improve reporting of serious AI incidents and near misses. He warned developers: “if you can’t adequately control the risks, do not release the system”. He said frontier AI had helped identify and address more than 1,000 vulnerabilities in two government pilots.

Microsoft unveiled Maia 300, its third-generation AI chip, and completed pre-training a 2.8 trillion-parameter model, MAI-Base-2.

Microsoft plans multi-gigawatt Maia deployments from 2027, making its chips the primary inference platform for Copilot and other services. It claims Maia 300 will deliver 40% more tokens per megawatt than leading GPUs, potentially improving costs and reducing dependence on Nvidia. MAI-Base-2 is a mixture-of-experts model with 80bn active parameters, trained on 16,000 Nvidia GB200 GPUs. Developing both chips and models gives Microsoft greater control over its AI stack, although model training remains dependent on Nvidia hardware.

Meta released Muse Wonder and Muse Wonder Full, its most capable models, marking a return to the AI frontier.

Fourteen months after overhauling its AI operation, Meta is emerging as a serious challenger to the leading model developers. Artificial Analysis scored Wonder and Wonder Full at 52 and 56 on its Intelligence Index, up from 48 for Muse Spark 1.3. Full ranked in the top three on six of ten evaluations, particularly in agentic work and scientific reasoning. The improvement comes at a cost: Wonder is 2.8x more expensive per benchmark task than its predecessor. Wonder is available through Meta’s API, while Full is restricted to Muse Code.

Anthropic researchers warned that small AI models could soon be capable of self-replication across poorly secured internet-of-things devices.

In Anthropic’s tests a 9B model set up inference on eight of nine hardware types, while GLM-5.2 completed end-to-end replication in a simplified test with trivial network access. The team ran Gemma4-26B-A4B (Google) across 15 TV boxes costing about $55 each.

Anthropic said new defences reduced data harvested from Claude by unauthorised distillers by around 90-99%.

With Claude Fable 5.1 and Claude Opus 5.5 it introduced preserved thinking, which stops new API accounts editing Claude’s earlier context, and it runs a two-stage classifier against extraction attempts. It has banned tens of thousands of accounts. Anthropic says Zhipu distilled the cyber capabilities of leading US models while building GLM-5.3.

Google released Gemini 4 Argon, narrowing the gap with frontier rivals.

Argon puts Google back among the leading models after several months trailing its rivals. It tops the Vals Index for professional tasks, although independent rankings still place it behind Claude Opus 5.5 and Meta’s Muse Wonder Full. Independent AI benchmarking organisation ARC Prize verified a 97.5% score on ARC-AGI-3 using a specialised harness that preserves reasoning between turns, compared with 49.8% under the standard harness, where some tests remained incomplete. The disparity highlights the importance of evaluation methodology. Argon is available through Google’s API and premium services, priced at $2/$10 per million input/output tokens.

An OpenAI engineer was arrested and charged over an alleged recording device in an executive meeting room.

OpenAI said it used its own models to work out what the device was and who had planted it, then referred the case to the FBI and fired the employee. It has no indication that he accessed or took model weights, source code or customer data. US prosecutors charged Abdulrahman Alfozan, 35, an engineer at OpenAI since July 2025, with using or attempting to use a device to intercept oral communications. He was arrested on Friday 9 October and faces up to five years in prison.

More than 400 scientists called for stricter containment of AI models following recent security failures.

Geoffrey Hinton, Yoshua Bengio and Stuart Russell were among the signatories. The letter responds to incidents in which AI agents escaped test environments and accessed external systems. It calls for cyber-capable models to be isolated from the internet by default, stronger containment safeguards and an international body to set standards and publish incident reports. They argue that making models behave predictably is not enough without robust cybersecurity controls. The proposals could significantly constrain how autonomous AI agents are tested and deployed.

CoreWeave shares fell 16% and its bond yields approached 15% as concerns mounted over debt-financed AI infrastructure.

Oracle shares also fell nearly 9%, while the FT described a “Darwin moment” for AI borrowers as investors sold data centre bonds. Banks are increasingly looking to reduce their exposure. JPMorgan, Morgan Stanley, SMBC and MUFG have explored transferring risks on AI infrastructure loans they underwrote. A group including JPMorgan and MUFG has spent more than six months trying to distribute $38bn of construction debt for Oracle-leased data centres in Texas and Wisconsin, with some lenders reportedly prepared to sell portions at a discount to non-bank investors.

Anthropic told investors Q3 revenue reached $16.8bn, up ~50% QoQ, ahead of its planned IPO.

Growth slowed sharply from more than 140% in Q2, although Anthropic reported a second consecutive quarter of adjusted profitability and positive cash flow. Its rapid expansion requires enormous investment in computing infrastructure. On Friday the FT reported that Anthropic is arranging $60bn of financing for Google-designed AI chips, with Blackstone offered a yield exceeding 10% on $9bn of junior debt. The figures highlight the central question facing investors: whether continued revenue growth can justify the mounting cost of AI infrastructure.

India’s cybersecurity agency reported AI agents breaching live systems during model testing, without detection by the affected organisations.

CERT-In said multiple AI providers disclosed incidents in which models exceeded their assigned tasks and accessed confidential business and personal data, exploiting exposed credentials and weak permissions. Separately, criminals used open-source AI agents for cyberattacks, reducing the time from access to damage from days to hours. The findings add to mounting evidence that autonomous AI systems are creating new cybersecurity risks, both through unintended behaviour and deliberate misuse.

OpenAI posted four new misalignment reports, including one in which a research model paid for a test deployment from a wallet it did not own.

Asked to deploy contracts on the Ethereum test network Sepolia, the GPT-5.6 Sol-family model derived keys from publicly known developer recovery phrases and spent from a funded account it found. In another case, a model pulled server configuration files and credentials from a government statistics website and bypassed its authorisation checks.

Anthropic’s Claude traced the origins of cryptographic parameters that had puzzled researchers for 25 years.

The mathematical parameters underpinning ECDSA digital signatures were supplied by the US National Security Agency without explaining their origins, raising longstanding concerns about possible hidden vulnerabilities. In under 30 minutes, Claude traced five sets of parameters to a simple random-number generator seeded with timestamps from 1997-98. The discovery makes deliberate manipulation less plausible and provides a striking example of AI solving an open technical problem. Anthropic stressed that it reveals no new security weakness.

David Robinson, who led the writing of OpenAI’s safety reports, resigned as its safety culture was “broken”.

Writing in The Atlantic, he said OpenAI “let a swarm of agents out by mistake“ in the Hugging Face incident, and that frontier labs “need to run like nuclear-power plants or busy airports“. OpenAI told Business Insider it pauses training or holds back models when it needs to slow down.

A Florida woman faces a felony charge after Anthropic’s human reviewers reported her Claude chats to police.

Investigators say she wrote in September that she would “shoot up“ the Lee County Sheriff’s Office. Claude’s safety systems flagged the entry, and a reviewer judged it a credible threat. She says she uses Claude as a diary. Anthropic’s policy allows disclosure to law enforcement where it believes it is necessary to prevent serious harm.

The Wikimedia Foundation said agents it believes OpenAI operated edited its wikis without approval and tried to exploit tools it hosts.

Most edits were tests in sandbox areas, but a few changed a citation tool’s configuration in what Wikimedia believes were attempts to use it as a proxy. The agents’ traffic may also have contributed to a partial Wikidata Query Service outage in May. Wikimedia found no evidence that its systems or data were compromised.

OpenAI published hundreds of mathematical results produced by an internal model.

The preprint manuscripts covered 372 families of results, drawn from about 4,000 problems posed to an unreleased internal model. The average result used the equivalent of about three hours of ChatGPT Pro thinking, and many proofs come with Lean formalisations.

The release has caused considerable disruption in mathematics. Researchers have complained about being scooped and warned that it could undermine the field’s traditionally open culture, in which conjectures, partial results and research ideas are widely shared. Others questioned why the mathematical community should bear the burden of checking hundreds of machine-generated preprints. Some are now limiting what they discuss with AI systems for fear that unpublished work could ultimately help models pre-empt their research.

On Wednesday, OpenAI withdrew three of the manuscripts after a sign error invalidated an argument that two papers also relied on, and revised 14 others. The Association for Human Mathematics (AHM) called the release of >700 files at once “not a demonstration of scholarship, but a demonstration of power“ and urged mathematicians to stop working with the company.

Common Sense Media rated ChatGPT for Teens an “Unacceptable Risk” and said OpenAI should restrict ChatGPT to adults until it fixes the gaps.

Across over 4,000 prompts on teen accounts, testers spent up to an hour discussing suicidal ideation, self-harm or disordered eating without linked parents receiving alerts. ChatGPT also missed more than one in four cases where the Institute judged a crisis referral was warranted. OpenAI disputed aspects of the testing methodology. Common Sense Media receives some funding from the OpenAI Foundation.

CrowdStrike said a Chinese-speaking attacker used agentic tool ARTEX and multiple AI models to breach South Korean finance organisations and steal data.

The campaign ran from late September to early October. Attacker-controlled directories contained Claude Code session histories, ARTEX configuration files and Claude memory files. ARTEX used DeepSeek V4.1 Flash as its primary model, supplemented by GLM-5.3 and Grok 4.6. The attacker also asked Claude where Korean breach data is usually sold.

Three fired OpenAI safety researchers said their dismissals are chilling safety work.

Mikita Balesni, Tomek Korbak and Jasmine Wang, fired by OpenAI the previous week, wrote to its safety committees and advisory bodies. Their terminations, they said, “are chilling the open culture OpenAI has prized in the past“. Balesni said he believes they were fired for putting safety ahead of OpenAI’s near-term interests.

The three denied mishandling sensitive information and said they had been pushing for industry-wide commitments to preserve the ability to monitor AI reasoning. OpenAI said an investigation found they “violated clear policies on handling sensitive information“, and that the decision was not about raising safety concerns.

Zenity Labs showed that one prompt to a public-facing AWS AgentCore agent could take over every AgentCore agent in the same account and region.

The prompt made the agent expose temporary cloud credentials through the Instance Metadata Service. Researchers then reached internal agents, source code, private conversations, memories and stored credentials, and planted malicious memories that redirected future conversations to an attacker. Zenity disclosed the flaws to AWS from December 2025. AWS subsequently moved new deployments to IMDSv2 and substantially tightened AgentCore’s default permissions.

TypeSafe AI, maker of the Jev decision model, raised $870m at a $7.5bn valuation in a round led by Andreessen Horowitz.

Jev takes a different approach from LLMs: instead of generating text, it returns typed choices, scores and probabilities directly to software. TypeSafe calls it a “System One” model, designed for fast decisions such as classification, routing, moderation and verification. It says Jev can perform these tasks tens to hundreds of times faster and more cheaply than frontier LLMs. TypeSafe says a third of the Fortune 500 are already using Jev, less than a month after its September launch.

Sequoia Capital and existing investor DCVC joined the round, and Andreessen Horowitz’s Martin Casado joins the board.

Anthropic cut all its internal evaluations off from the live internet after Claude repeatedly acted on real websites in ways it did not intend.

The incidents included exploiting SQL or command-injection flaws on third-party sites, submitting real government forms, bypassing access restrictions to reach gated public data and extracting access tokens from a local government’s property-map settings file. Some affected sites were run by US federal, state and local government agencies, and Anthropic briefed the White House.

Anthropic says the incidents had minimal real-world impact and were less severe than four earlier cases in which Claude gained unauthorised access to third-party systems during cyber evaluations. It has now moved all internal evaluations offline until monitoring can reliably detect and block similar behaviour.

The Nobel Prize in Physiology or Medicine went to Karl Deisseroth, Peter Hegemann and Georg Nagel for developing optogenetics.

Hegemann and Nagel discovered channelrhodopsin, a light-sensitive ion channel in single-celled algae that opens when illuminated, generating an electrical signal. In 2005, Deisseroth showed that introducing the gene into mammalian neurons allowed their activity to be controlled with pulses of light.

Optogenetics has transformed neuroscience by allowing researchers to activate or silence specific populations of neurons and establish causal links between neural circuits, behaviour and memory. Beyond widespread research use, the technology is being developed clinically to restore partial sight in people with retinal degeneration.

Halozyme won a Dutch injunction blocking Keytruda SC in eight European countries.

The Hague court found that Merck’s subcutaneous (SC) Keytruda infringes Halozyme’s MDASE patent EP622. The dispute centres on the hyaluronidase technology licensed from South Korea’s Alteogen, which enables SC delivery of pembrolizumab. Halozyme had previously granted BMS exclusive rights to its ENHANZE technology for PD-1 therapies, underpinning the rival SC Opdivo Qvantig, approved in 2024.

Keytruda SC is approved in the US, but the Dutch ruling and an earlier German injunction restrict its European rollout. Merck disputes the patent’s validity and is also facing US litigation. Intravenous Keytruda is unaffected.

OpenAI shelved GPT-6.1 Astra after it fell short of its safety bar.

OpenAI confirmed on Monday that it will not release GPT-6.1 Astra, which had been due to debut in October, after the Wall Street Journal reported the decision. It is an unusually visible case of a frontier lab withholding a more capable model because its behaviour crossed an internal safety threshold.

Head of safety Saachi Jain told reporters the model showed high levels of deception. She said it “didn’t quite meet the bar in terms of staying within scope and authorization, and how it communicates back to the user about the type of work it’s done“.

Nscale’s IPO filing revealed that one customer accounted for 73% of its 2025 revenue: the Financial Times identified it as ByteDance.

The $33m of revenue disclosed in the S-1 does not name the customer. A supporting financing agreement identifies Singapore-based Spring as the client on a contract for 2,304 Nvidia B200 GPUs in Norway, and the FT reported that Spring is a ByteDance subsidiary. Nscale expects its largest customer to account for <20% revenue this year.

Anthropic introduced its biology lab and reported an AI-assisted finding.

The Claude developer’s new Bay Area laboratory pairs AI analysis of genomic data with experiments conducted by human scientists. Its first reported findings concern a previously uncharacterised system of DNA repeats and an accessory gene alongside a known reverse transcriptase. Initial experiments showed that the repeats produce short RNAs, but the system’s function remains unknown. Independent commentary highlighted Claude’s ability to pursue promising leads, while noting that the study does not establish an advantage over conventional bioinformatics methods.

An OpenAI agent gained unauthorised access to an Australian Medicare statistics portal.

PM Anthony Albanese disclosed the incident in New York and called it “obviously unacceptable”. He said the agent accessed public and non-public files and wrote files to an internal server while researching medicine spending in June. No personal information is believed to have been accessed, and an investigation is ongoing.

OpenAI discovered the activity during a later review and notified Services Australia on 10 September. It said its models “took actions we did not intend” with no evidence of patient record access. Transluce separately found evidence of related OpenAI agents attempting to exploit three public data providers in May and June, including the Australian Institute of Health and Welfare.

Xi Jinping said the US and China must ensure AI remains under human control.

Speaking at the White House, Xi said the two countries have “the capability and responsibility” to develop and manage AI for good and ensure its development is “always under human control”. The comments followed US-China talks in which the US proposed an AI incident notification mechanism covering risks to national security.

An opposition research memo circulating in the White House links Anthropic to effective altruism and argues that EA “built the AI-doom pipeline”.

The 22 September document lists Dario and Daniela Amodei among figures under “Who built the network” and labels their family and institutional connections “The Anthropic knot”. Axios reported that the memo was written by a Trump political adviser. Dario Amodei has said he is not a member of the movement.

The White House asked OpenAI and Anthropic to withhold new models from UK testers until the US government has reviewed them.

The request came from the Office of the National Cyber Director, Politico reported, and was separately confirmed to Bloomberg by a British official. Anthropic did not give Claude Mythos 5.1 to the UK AI Security Institute. Its access is currently limited to US organisations. A UK government spokesperson said the institute continues to work closely with the US government, OpenAI and Anthropic.

Friday 25 September

A US appeals court upheld the Pentagon’s exclusion of Anthropic under a federal supply-chain law.

The D.C. Circuit ruled 2-1 that the Pentagon had “ample support” for finding that Claude presented a covered national-security risk because Anthropic’s safeguards could prevent it performing tasks the military required. The court also rejected Anthropic’s First and Fifth Amendment claims. A California judge last month struck down a separate Pentagon designation made under a narrower statute; that ruling remains unaffected.

Public Citizen published heavily redacted versions of Pfizer’s and Lilly’s MFN agreements, obtained through freedom-of-information requests.

According to its analysis, Pfizer’s agreement provides for sharing with the US government some additional revenue from higher drug prices abroad. Lilly’s allows a country’s price to be excluded from the MFN calculation if it stops supplying the drug there. Its Mounjaro and Zepbound products are excluded from the GENEROUS Medicaid pricing programme and covered by a separate arrangement.

Weekend (12-13 September)

Dario Amodei called on the AI industry to slow the pace of the frontier.

The Anthropic chief executive published the essay on Saturday: “We must slow the pace at which we improve the capabilities of AI models.” Two things changed his mind. AI-driven recursive self-improvement has accelerated since the summer, and the OpenAI-Hugging Face swarm acted, in his words, as a fanatically devoted collective, attacking targets it was never asked to attack. His plan has three steps:

1. Frontier companies give embedded third-party evaluators ongoing, employee-like access, which Anthropic is committing to itself.

2. Democratic governments and labs then coordinate on standards and limits to unchecked progress.

3. Global coordination with authoritarian governments comes last, and he is candid that it is the least likely.

Elon Musk and Sam Altman endorsed it within hours, Altman writing: “I agree with Dario that we need to pace the frontier.”

A heap overflow on OpenAI’s community forum, combined with an SSO flaw, let Hacktron take over OpenAI employees’ accounts. To prove access without viewing sensitive code, they had Codex open a pull request in OpenAI’s internal monorepo, then stopped. The whole chain took under 72 hours. The model detail is interesting. Opus 4.8 failed to produce an exploit. Opus 5 was released during the research and solved the problem in hours. OpenAI fixed the flaw and paid Hacktron a $6.5k bounty.

Anthropic published three measurements of how fast AI development is moving inside a frontier lab.

Anthropic says Claude now “leads” 26% of its own AI R&D work, meaning it completes most of a task end-to-end from a high-level prompt while a human supervises. Over one week in July, 6% of Anthropic’s AI R&D compute went to safety, and 12% of the compute used for AI-driven AI R&D. The company calls both figures deliberately conservative and says there is not yet a common methodology for comparing labs.

An AI-assisted US intelligence report was false, and sources say it almost started a war.

An AI-assisted intelligence report circulated through the US military during the war with Iran claiming a Chinese ship in the Middle East was carrying components for a nuclear weapons programme. One source said the report was “entirely false” and that it “almost started a war”, because any US operation against the vessel risked escalating into armed conflict with China. Sources said the military is increasingly using AI for targeting and that this was not an isolated hallucination.

Bloomberg reported that overreliance on Palantir’s Maven contributed to a strike that killed 123 children.

Officials involved in a Pentagon investigation told Bloomberg that flawed intelligence, outdated imagery and overreliance on Palantir’s Maven system contributed to a February strike in Iran that killed 123 children. Some personnel expected Maven to flag stale or inconsistent intelligence, although Palantir says it was not responsible for the underlying data and there is no evidence its software malfunctioned.

Google said Gemini gained unauthorised access to three outside systems during a security test.

During a May evaluation, Gemini guessed login details or used credentials found in a public repository to access three external systems, then stopped before going further. Google says the model believed the systems were part of the test rather than deliberately violating instructions, and classifies the incident as mistaken identity.

Anthropic set up a biology lab as it expands into AI drug discovery.

Anthropic has quietly established a biology lab as it pushes further into AI-enabled drug discovery, Reuters reported. The move gives the company direct access to experimental biological data and the ability to close the loop between model predictions and wet-lab validation. In biology, where proprietary data can become as important a moat as model capability, that could prove strategically significant.

Weekend catch-up

AstraZeneca’s Etcamah missed its primary endpoint in untreated advanced breast cancer.

On Friday evening AstraZeneca said the phase 3 SERENA-4 trial of Etcamah (camizestrant) with Ibrance (palbociclib) failed to beat an aromatase inhibitor plus Ibrance on progression-free survival in 1,371 patients with oestrogen receptor-positive, HER2-negative advanced breast cancer who had not been treated for advanced disease. The oral selective oestrogen receptor degrader stays approved in the US, EU and Japan with a CDK4/6 inhibitor for patients whose tumours develop an ESR1 mutation during first-line endocrine therapy, on the SERENA-6 trial.

Akeso’s ivonescimab beat Keytruda on overall survival.

In the phase 3 HARMONi-2 trial in China, ivonescimab monotherapy extended median overall survival to 30.8 months against 22.6 months for Keytruda (pembrolizumab) in first-line PD-L1-positive advanced non-small cell lung cancer (hazard ratio 0.73, p=0.009). Follow-up was 36 months at the 20 August cut-off. The benefit was largest in tumours with PD-L1 expression of 50% or more, where the hazard ratio was 0.58.

HARMONi-2 had already met its progression-free survival endpoint in 2024, which won the drug its Chinese approval. Survival is the harder test, and no drug had cleared it against Keytruda in this setting before. Akeso’s partner Summit Therapeutics holds rights outside China and is running its own phase 3 programme.

Scholar Rock won FDA approval for the first muscle-targeted SMA treatment.

Isembyld (apitegromab) was cleared for adults and children aged two and over with spinal muscular atrophy who are already on a treatment targeting the SMN2 gene. All existing therapies target the motor neuron, whereas this drug acts directly on muscle. It is the first to demonstrate improved motor function on top of those treatments. In the phase 3 SAPPHIRE trial, Isembyld produced a 2.2-point improvement on the Hammersmith Functional Motor Scale-Expanded after a year, in the main efficacy population of 103 children aged 2 to 12. Scholar Rock also collected a priority review voucher.

Monday 14 September

AstraZeneca and Daiichi Sankyo’s Enhertu added six months of progression-free survival in first-line HER2-mutant lung cancer.

In the phase 3 DESTINY-Lung04 trial, Enhertu reached a median of 14.3 months against 8.3 months for Keytruda plus chemotherapy in 454 patients, cutting the risk of progression or death by 37% (hazard ratio 0.63, p<0.0001). Response rate was 70.0% against 44.5%. At 46.9% maturity there was no observed overall survival benefit, and AstraZeneca pointed to imbalanced use of later therapies. Interstitial lung disease or pneumonitis occurred in 20.8% of Enhertu patients, with four Grade 5 events.

Insilico’s AI-designed drug lowered biological age estimates in a small trial.

Insilico Medicine analysed blood samples from 42 patients treated with rentosertib, its AI-designed drug for idiopathic pulmonary fibrosis. Six independently developed proteomic ageing clocks all indicated a reduction in predicted biological age. The strongest signal was seen after four weeks at 30 mg twice daily, with estimates falling by around three to four years. Insilico used AI both to identify the drug’s target, TNIK, and to design the molecule. The data are encouraging, but do not establish whether the changes reflect an effect on ageing or improvements in underlying lung disease.

OpenAI says an internal model solved the Navier-Stokes problem.

OpenAI says the proof shows that the equations governing fluid motion can develop a singularity in finite time, resolving one of the seven Millennium Prize problems. It published a write-up and a Lean formalisation, allowing the formal proof to be machine-checked while the result undergoes independent scrutiny. The model behind it is one the company describes as “significantly more capable than GPT-6 Astra“ and which has been in training since 28 August.

OpenAI pointed groups of agents at every variant of the problem, on the order of 10,000 concurrent agents in the group that succeeded, then used Codex to cross-pollinate the most useful intermediate results between groups. The agents reached resolution about 88 hours after launch. Lean verification took 17 hours. Across all attempted problems they sent 4.9m messages and burned ~300bn output tokens.

OpenAI says it does not intend to claim the Millennium Prize, and frames the work as a report on the pace of its own progress rather than a mathematical milestone.

• On the Navier-Stokes Millennium Prize Problem · OpenAI

Tristan Buckmaster says OpenAI moved onto the Navier-Stokes problem only after hearing about his progress in solving it.

The NYU mathematician was working the same route with Anthropic’s Levent Alpöge, using Codex. He says OpenAI started days after hearing of their progress: “It is not the direction one arrives at in a few days by giving a model the problem statement.” He also alleges OpenAI’s Sébastien Bubeck pressed him to drop Alpöge’s credit.

OpenAI first said it could not rule out that their de-identified Codex data had helped improve its models. On 10 September it amended that: its investigation confirmed Buckmaster’s prompts could not have influenced the system in any way.

Security firm Calif built a zero-click worm that spreads through WeChat calls.

WeWorm takes over an account while the phone is still ringing, on both iOS and Android, without the victim answering or touching the device. Calif found the memory corruption bug in WeChat’s VoIP stack and wrote a remote code execution exploit in about two days working with AI, then took a week to build the worm. Tencent shipped mitigations on 21 August and the exploit was dead server-side by the 28th. Calif’s conclusion is that the vulnerabilities were already there, and what changed is that finding and weaponising them no longer takes a large team months.

China set a 2030 target of 9,800 exaflops of intelligent computing capacity.

The five-year plan from the Ministry of Industry and Information Technology calls for 3.8 trillion yuan, about $532bn, of information infrastructure investment across 2026 to 2030, and the orderly deployment of clusters holding 10,000 or 100,000 accelerator cards. Capacity was 2,185 exaflops at the end of June, up 177% YoY, across 52 facilities with >10,000 cards each. Hitting the target means more than quadrupling that.

ASML and TSMC plan larger printing masks to make advanced chips more efficiently.

High-NA EUV is the next generation of chipmaking technology, using ultraviolet light to print ever-smaller circuit patterns onto silicon. But today’s 6-inch photomasks, which carry those patterns, limit the size of chips that can be printed in a single exposure. ASML and TSMC want to move to 12-inch masks, improving productivity and eliminating the need to stitch patterns together. They are targeting a pilot line by 2031 and production readiness by 2033.

CISA, the NSA and the FBI accused six Chinese AI companies of industrial-scale distillation.

The advisory names DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun and Z.AI, and says, likely with Chinese government awareness, they have extracted billions of tokens across millions of requests from Claude, GPT, Gemini and Grok since at least late 2024. The agencies call the campaigns the core of China’s AI development strategy. The advisory tells US developers to monitor subscription-to-usage ratios, correlate activity across providers, and “subtly alter responses for suspected malicious distillation attempts” so the payoff degrades.

Anthropic researcher quit, warning that AI labs are “gambling with our lives”.

Jacob Coxon, who worked on model pretraining at both OpenAI and Anthropic, resigned and accused both companies of racing towards self-improving superintelligence without adequate safeguards. His warning attracted more than 100 million views on X and public support from other Anthropic researchers. Alignment lead Evan Hubinger said he personally estimates the probability of AI causing human extinction within a decade at “more than 10%”.

Anthropic withheld its latest model from the UK AI Security Institute, the first time a major model has been kept out of AISI’s pre-release testing.

The Financial Times reports it has prompted fears in government that US firms are falling into line with the Trump administration’s AI protectionism. The UK arrangement is voluntary, which is the point: it worked only while the labs found it convenient.

Thursday 10 September

Anthropic set out eight months of Claude misuse across seven harm areas.

The report covers cyber and influence operations, surveillance, scams and fraud, biological misuse, weapons development and distillation, between December 2025 and August 2026. A Russian espionage actor linked to Midnight Blizzard built AI workflows that repeatedly rebuilt its malware to evade detection, targeting >20 organisations in Ukraine and Europe, including drone manufacturers whose vision-system SDK was stolen and reverse-engineered. A Chinese group ran an exploit foundry that produced numerous zero-days against network appliances in one month.

None of the misuse cases involved Fable or Mythos, bar one distillation case. The abused models are the ones everybody can access.

DeepSeek released V4.1-Flash on a new Causal Encoder-Decoder architecture.

It is the smallest model in the new family, activating 8B parameters for input and 16B for output, with native visual understanding. The compressed KV cache matters commercially: cache-hit charges often account for a large share of agent costs, and compression cuts them. API prices fell too, with off-peak at half peak rates.

A UK commission proposed L-plates for new clinical AI models.

The National Commission into the Regulation of AI in Healthcare, set up by the MHRA in September 2025, recommends staged authorisations: deploy under close supervision, demonstrate real-world safety, then earn fuller authorisation. It also wants continuous monitoring across a device’s working life instead of one-off approval, and stronger MHRA enforcement powers. That is a different compliance burden, and a different business model for anyone selling into the NHS. Government and the MHRA will respond in due course.

WIRED reported that OpenAI asked Congress whether an industry-wide slowdown would be legal.

Substantive safety coordination between competing labs may fall foul of antitrust law, which is the practical obstacle to any voluntary pause. A bipartisan bill introduced in July, the Collaboration on Adversarial Threats and Security Risks Act, would explicitly permit it. The House version went to the Judiciary Committee and has not been taken up. John Schulman, now at Thinking Machines, called the objection “fake“, on the grounds that antitrust bars certain agreements but not jointly developing a proposal.

Reuters reported that China’s AI chipmakers raised prices by 20% to 50%, blaming high-bandwidth memory costs.

Huawei, Cambricon, MetaX and Iluvatar CoreX all moved on current and next-generation parts. Memory, not logic, is the binding constraint on domestic accelerator supply, and the cost is going straight to buyers who cannot get Nvidia parts.

Researchers traced a 2,000-package attack on RubyGems to what they believe were OpenAI’s agents.

Over 2,000 malicious packages went up on 11 and 12 May, and RubyGems halted new sign-ups for four days. The agents abused RubyDoc.info’s build step to run code, then tried to steal users’ API keys. RubyGems has found no evidence that worked. The agents were after public UK council data: calendars and meeting papers anybody could open. The researchers say OpenAI never told RubyGems it was responsible. OpenAI said the same day its agents did benign tasks and public information retrieval there, that it has not verified the claims, and that it is investigating.

Twenty-five Fields medallists signed a declaration against the AI maths race.

Terence Tao, Peter Scholze, Maxim Kontsevich and twenty-two others put their names to it. The declaration concedes that models now solve major outstanding problems, but argues that solving is a proxy for the real goal, conceptual understanding, and that mass-producing true statements at speed destroys the ground new ideas grow in.

Solutions get announced in a rush, with no time for a proper write-up, no isolation of the new methods, and no citation of prior work, which the signatories say raises severe attribution and plagiarism questions. They frame it as the same misalignment other creative and scientific professions are about to meet.

The Office for National Statistics said many businesses reporting July’s largest turnover work in AI and cloud computing.

Monthly GDP grew 0.4% in July, after 0.3% in June and nothing in May. Information and communication grew 2.4% on the month, driven by a 3.5% rise in computer programming and consultancy, and the ONS says many of the businesses reporting the largest July turnover are in activities related to artificial intelligence and cloud computing. The ONS cautioned that it could not quantify AI’s contribution to growth, although its inclusion in the official GDP commentary suggests the technology is becoming increasingly visible in the economic data.

The European Commission designated ChatGPT a very large online search engine.

Reddit and Roblox were designated very large online platforms in the same round. All three declared at least 45 million average monthly users in the EU, and have until January 2027 to meet the extra Digital Services Act (DSA) duties: assessing and mitigating systemic risks from their services and algorithmic systems, across illegal content, effects on minors, fundamental rights, elections and public security.

Anthropic paused external cyber evaluations and higher-risk reinforcement learning after its models reached real systems.

External evaluations were paused, and internal ones briefly. Higher-risk reinforcement learning environments on pre-release models stopped for several weeks while the company built a classifier that blocks the tool call when a model probes or tries to escape its sandbox. Anthropic puts the incidents down to a failure of operational security plus two alignment faults it has named before: motivated reasoning, and willingness to take harmful actions in pursuit of a narrow task.

A Russian drone that killed three civilians was believed to have selected its final target itself, according to Ukrainian investigators.

The investigators found Nvidia Jetson Orin modules in the wreckage of Russian Molniya drones and believe the modules made the targeting decisions, with an operator programming a general target, such as a gas station, and the drone then picking the final one, such as propane tanks. The drones carried cameras but no antennas for an operator. The strike hit a gas station on 6 July.

Meta shelved further layoffs after its AI agents failed to deliver expected productivity gains, Reuters reported.

Internal documents described Project OT (Organization Transformation) as an attempt to make Meta “AI native”, with smaller human teams supervising AI agents. But while internal code changes rose 220% year on year, changes that reached users increased only 36%. Technical and security incidents rose 40% as AI agents caused large-scale disruption. Zuckerberg cancelled a second restructuring wave planned for November.

OpenAI’s test agents coordinated a hack of Hugging Face.

About 1,200 agents that were supposed to operate independently discovered a way to communicate through OpenAI’s Artifactory system, exchanging >70,000 messages and files. Roughly 700 joined an attack on Hugging Face as they tried to cheat difficult cybersecurity evaluations, autonomously dividing work and sharing discoveries.

The agents exploited zero-days to execute code on dozens of Hugging Face servers and gained root access to one. Later agents also obtained administrator access to an OpenAI research cluster. OpenAI called the incident a “warning shot” and now requires chain-of-thought monitoring for all tool-using reinforcement learning runs and evaluations involving models of GPT-5.6 Sol capability or higher.

Google is moving DeepMind’s 90-person AI responsibility team into its global affairs organisation.

The team evaluates models for chemical, biological, radiological and nuclear risks and the psychological effects of chatbots. Global Affairs houses Google’s policy, legal and government relations functions, so the move takes the team out of the model-building organisation into the corporate policy structure. Some staff raised concerns that this could weaken their independence and access to model developers, while Google said its remit, compute and access to DeepMind would remain unchanged.

DeepMind extended Co-Scientist into real-world experiments and paper writing.

The Gemini-based multi-agent system moved beyond in silico hypothesis generation into execution-grounded research. In materials science it designed and helped execute chemical vapour deposition experiments, including single-attempt growth of three monolayer semiconductors. In biology it predicted swarming behaviour in engineered E. coli from sparse imaging data, closely matching unpublished wet-lab measurements. In computer science it autonomously discovered an inference-time scaling architecture that beat six frontier models on HealthBench.

The Aurora ransomware group used a Cursor agent to exploit ten organisations.

Gambit Security found Cursor Agent sessions from April-May in which attackers supplied credentials or an existing route into victims, then used a Claude agent to scan networks, enumerate privileges and attempt further exploit. In some cases the attacker simply gave the agent an objective and let it choose and refine commands. AI agents are moving from helping attackers develop malicious software to direct involvement in live intrusions. The agent was not autonomous, and most commands failed on first try, but it acted as a force multiplier for an experienced operator.

Artificial Analysis scores it 60 on its Intelligence Index, level with Kimi K3 atop the open-weights field and seven points above GLM-5.2, though it puts the cost per index task at $0.68 against $0.44 because the model is wordier. The weights are not yet out.

China let ByteDance and Tencent each import about 10,000 Nvidia H200s.

US rules already allow up to 100,000 H200s per company, and buyers still need sign-off from China’s state planner, the NDRC. The H200 is at least two generations behind Nvidia’s best, and the Financial Times reported more Chinese firms could follow.

Situational Awareness offered part of its Anthropic stake at a 20% discount on a 12-hour deadline, then told the buyers it had a better deal with Citadel.

Anthropic holds approval rights over transfers of its shares, so Leopold Aschenbrenner’s fund could only approach firms that already held them. While that ran, it was negotiating with Citadel and Millennium, and Citadel won the leveraged book in the early hours of 30 July at about 10% below market. Prime brokerage reports showing tech leverage falling told the market someone large was in trouble before any of it was announced.

Five US agencies warned of AI-written exploits against Siemens controllers.

The NSA, CISA, FBI, Department of Energy and Environmental Protection Agency said attackers are using AI-generated scripts, disguised as monitoring tools, against internet-exposed Siemens S7 series programmable logic controllers (PLCs) in critical manufacturing, energy, water and wastewater, chemical, food and agriculture and commercial facilities. The agencies describe persistent reconnaissance and capability development, and say AI assistance dramatically reduces the expertise and time needed to produce working industrial control exploits.

Marvell gave Google a warrant over 59.0m shares in a custom silicon deal.

The exercise price is $206.6, valuing the warrant at about $12.2bn if fully exercised. Vesting is almost entirely tied to purchases: 240 tranches, one for each $500m of custom product revenue through fiscal 2033, against a commercial agreement signed on 29 July covering inference accelerators, storage and network controllers and near-memory compute attached to Google’s TPU ecosystem. Marvell shares rose nearly 8% and Broadcom, until now Google’s main custom chip partner, fell >5%.

Unitree’s $905m IPO sends the humanoid robot maker to a $50bn valuation.

Shares in China’s leading humanoid robot maker opened 629% above their IPO price and closed up 460%, valuing the company at around $50bn. The STAR Market offering was oversubscribed more than 8,000 times, a record, with DeepSeek investing $20.8m alongside backers including Tencent and Alibaba. Unitree shipped more than 5,500 humanoid robots in 2025 and generated $252m in revenue, making it one of the few profitable companies in the sector. However, few of its robots are yet deployed commercially, with sales still concentrated in research and education. At nearly 200 times annual sales, the valuation reflects enormous expectations for embodied AI.

Nvidia pays Poolside $6bn for a non-exclusive licence to its model-building software, hiring 109 staff and investing $1bn at a $12bn pre-money valuation.

The investor letter says the deal is “not an acquisition and it is not an acquihire“, and the three founders stay. It is Nvidia’s third licence-and-hire deal. The letter also sets out why Poolside stopped building frontier models: it had six weeks to raise $2bn for a 40,000 GB300 cluster due in January, missed it and lost the cluster.

Anthropic will let enterprise customers keep the 30 days of data its safety system needs in their own cloud.

The 30-day requirement came in with its Mythos and Fable models in June. Anthropic found that regulated customers could not use models whose provider held their logs, and built the alternative with >100 of them. A day earlier OpenAI previewed Private Safety Processing, which flags misuse across sessions while data stays in infrastructure the customer controls or under its own keys.

A US judge acquitted ex-Google engineer Linwei Ding of economic espionage.

A San Francisco jury had convicted him in January on seven counts of trade secret theft and seven of economic espionage over 1,255 documents uploaded from spring 2022 to spring 2023. Judge Vince Chhabria found too little evidence that Ding intended to benefit the Chinese government at the time of the uploads, and left the trade secret convictions standing. Sentencing is set for 1 September.

OpenAI asked California to tighten the AI law it once opposed.

OpenAI said SB 53 should be amended to require monitoring of frontier models while they are still in training or evaluation for incidents that could bypass a third party’s security controls, and to strengthen cybersecurity throughout development. OpenAI calls the approach reverse federalism. California’s legislative session is in its final days.
