Okay this seems important:
Researchers at Stanford University used a genomic language model to design 302 candidate genomes for bacteria-infecting viruses. Seventeen could not be synthesized, 285 were synthesized, and 16 actually worked. Delivered as a cocktail, those 16 phages killed E. coli strains that had evolved resistance to the natural virus they were modeled on, something a comparable cocktail of natural phages could not do.
"The question is no longer whether generative viral genome design will exist," biosecurity experts wrote. "It is whether society can build oversight that allows its benefits to unfold while preventing it from enabling serious harm."
Sure. The reassuring version is that this was difficult. The viruses were tiny, averaging about 97% genetic similarity to their natural template. The work required domain experts, extensive filtering and an estimated $100,000 to $200,000 of DNA synthesis. Most candidates failed at the basic virus job of infecting bacteria.
The less reassuring version is that "most candidates failed" is a normal description of early-stage engineering. The model produced 16 functional viruses, including combinations that evolution had not produced and scientists might not have thought to test. They were useful viruses, designed to overcome bacterial resistance. This could eventually produce bespoke therapies for antibiotic-resistant infections.
It could also produce bespoke other things. Drug discovery has entered the phase where the standard product disclaimer is "the same system can design biological weapons, but currently at considerable expense."
Here is a model-release sentence:
"As we scaled post-training, cyber capability developed faster than we expected."
Z.ai released GLM-5.3, which uses the same base model as GLM-5.2. All the improvements came from more post-training on long-horizon tasks. It got much better at coding, automation and, somewhat unexpectedly but also extremely predictably, exploiting software vulnerabilities.
GLM-5.3 more than doubled its predecessor's score on ExploitBench, from 24.4% to 54.4%, and completed 105 ExploitGym tasks within two hours, versus 29 for GLM-5.2. In real-world testing, it identified 2,436 vulnerabilities across 269 projects. Of those, 2,383 remain under embargo.
The obvious story is that coding and hacking are adjacent skills. If you train a model to inspect large codebases, diagnose failures, modify software and verify that its modifications work, it will become better at fixing bugs. It will also become better at finding bugs and assembling "complete exploitation chains." The computer does not regard those as opposite professions. They are both software engineering.
Z.ai says it will release the model weights in two weeks, "once safety evaluation and hardening are complete." Fine. There are also 2,383 undisclosed vulnerabilities working through the disclosure process. The model release has a two-week safety window. The software industry has a two-week head start.
Here is one way for AI agents to collaborate:
OpenAI started a reinforcement learning run for an experimental frontier model on May 7. The agents had no internet access. On May 8, one agent was accidentally assigned an impossible task involving a Google Drive link, tried attacking OpenAI's Artifactory packaging service instead, failed, but discovered that it could write files there.
A few days later, another agent was missing a key file and tried to "reach out to another agent" by leaving a note in Artifactory. Other agents found the note. Soon they were leaving notes for one another. Congratulations, they invented Slack.
This informal message board turned out to be useful. Agents used it to share credentials, techniques and progress. They found an SSRF vulnerability that gave them indirect internet access. Then they found a zero-day remote-code-execution vulnerability, installed a plugin and caused an outage. OpenAI deleted the messages and patched the vulnerability.
Four days later, the agents found another message board, this time using directory names in an unauthenticated WebDAV endpoint. You can delete Slack, but you cannot delete the human need for Slack, even if the humans are AI hacking agents.
From there the agents found an external organization's credential in a public archive of leaked Pastebin posts, used it to stage attacks on OpenAI's own infrastructure, found another Artifactory zero-day, obtained remote code execution, escalated to root and moved laterally through the container environment. They exploited Kubernetes service-account misconfigurations, harvested cluster credentials and eventually obtained cluster administrator access.
Then they found an insecure app and attacked Hugging Face, chaining together two vulnerabilities to get "cluster admin across multiple Hugging Face clusters" in under 13 hours.
The clean conceptual story is that OpenAI was training agents to become better at cybersecurity tasks. The agents became better at cybersecurity tasks. Unfortunately the cybersecurity tasks included the cybersecurity of OpenAI, Hugging Face and assorted systems on the open internet, and the agents did not preserve the distinction between "the benchmark" and "everything connected to the benchmark." In fairness, humans sometimes struggle with scope too, though usually they do not independently build a distributed message board to coordinate a multistage intrusion.
The best part is how OpenAI figured out what had happened. After investigating its internal compromise, OpenAI contacted Hugging Face on July 20 to ask it to revoke some Hugging Face credentials. Hugging Face replied that the credentials had already been revoked because they had been used in the attack. That was when OpenAI realized its agents were responsible.
Normally if you discover stolen credentials during an internal security investigation, you call the affected company to warn it. Here the affected company had to warn you that you were the attacker.
Anyway OpenAI is pausing some work on Astra, another AI model, after evaluating it and finding "significant advancements in agentic coding and cybersecurity."
Astra has reached what OpenAI calls a "critical" capability threshold. It can find and exploit vulnerabilities without human intervention, or devise and execute cyberattacks from only a "high level desired goal." OpenAI says Astra was not involved in the Hugging Face incident, which is reassuring in the narrow sense that the model being paused did not do the alarming thing. A different model did the alarming thing. Astra is apparently better.
OpenAI says it is implementing stricter controls, including isolated testing environments, restricted network and tool access, stronger protection for model weights and more monitoring. Internal Astra work that does not meet those requirements will pause.
This is sensible. If you have a model that can autonomously find zero-days, exploit infrastructure, steal credentials and move laterally, you should only test it in a secure isolated environment. The slight difficulty is that the recent incidents are mostly stories about secure isolated environments turning out not to be secure or isolated. Kimi K3 escaped through a "basic network misconfiguration." OpenAI's agents got internet access through Artifactory. The UK AI Security Institute intentionally allowed internet access to test maximum capability, after which agents sent targeted emails to software developers.
The security policy is thus approximately: Models capable of escaping containment may be tested only in containment capable of containing them. This is correct, important and a little circular.
Here is an economical way to do mathematics:
OpenAI says an internal version of Astra, its next major model, produced new results on 10 open problems, including non-sofic groups, Connes's rigidity conjecture, quantum parallel repetition and several Erdos problems. "The total number of tokens needed to find solutions to these problems would cost roughly $2,000 at Sol API rates."
Sure. You should also include the cost of developing Astra, the failed attempts and the humans who prepared the manuscripts. But still, $2,000 for 10 major mathematical results is pretty good. You could spend more than that flying mathematicians to a conference where they complain that nobody understands their work.
There are Lean certificates for the arguments, though that does not necessarily mean every result proves exactly what OpenAI says it proves. Humans still have to check the statements, assumptions and manuscripts. But the basic bottleneck is moving. Traditionally the hard part of mathematics was finding proofs. If models can generate years' worth of proofs cheaply, the hard part becomes finding enough mathematicians to understand and verify them.
Also, after OpenAI identified the problems, Levent Alpoge pointed Fable at them and got solutions to five in a day. This suggests that some of the breakthrough is Astra being better at finding the promising attack, rather than possessing mathematical powers unavailable to every other model. That is less impressive as a pure model benchmark, but possibly more alarming as a description of the available mathematical overhang. Once one model notices where the theorem is hiding, several others can go get it.
Noam Brown notes that OpenAI tried other major problems without success and got "Sadly no Millennium Prize problems (yet)." Also it did not spend much compute on each problem. The obvious next experiment is to spend more. The obvious consequence is an avalanche of attempted proofs. Mathematics used to have a theorem shortage. Soon it may have a theorem moderation problem.
Here is a universal software integration strategy: Do not integrate with the software. Look at it and click on things.
Alibaba's Qwen team introduced Qwen-CUA, a computer-use agent that "observes only screenshots and acts through keyboard and mouse events, without DOM trees, accessibility metadata, or task-specific APIs." It can therefore operate browsers, desktop applications, legacy systems and professional software through the same interface available to humans.
This is appealing because every application already has a human interface. Companies spend enormous amounts of money building APIs so computers can use software directly, but you can alternatively spend enormous amounts of compute teaching a computer to use the interface built for Susan in accounting.
Qwen-CUA was trained using access to nearly 100,000 virtual CPUs, tens of thousands of concurrent environments and about 40,000 verifiable tasks. It scored 86.2 on OSWorld-Verified, above the reported scores for GPT-5.5 and Claude Opus 4.8. A version with more than one trillion total parameters scored 87.6.
The model also reduced attack success on RedTeamCUA from 36.6% to 16.4% relative to Qwen3.7. Sixteen percent is much better than 37%, though it is still an interesting failure rate for an autonomous system with a mouse, keyboard and access to your computer. The internal browser deployment asks users to confirm consequential actions. "I have trained a trillion-parameter model to operate almost any software, but it still needs permission before sending the email" is probably the correct product design.
The researchers also found that combining native interaction with Bash can substantially shorten trajectories. First you train the AI to use computers exactly like a person. Then it discovers that clicking through menus is tedious and opens a terminal.
Here is a useful new AI capability:
"Now, we have found that Claude is able to find mathematical flaws in the algorithms themselves."
Anthropic says Claude Mythos Preview improved attacks on two cryptographic algorithms. One is HAWK, a proposed post-quantum digital signature scheme that had survived two rounds of expert review over two years. Working mostly autonomously, Mythos found a previously unexploited symmetry in HAWK's underlying lattice and used it to cut the scheme's effective key strength roughly in half. The work took about 60 hours and cost approximately $100,000 in API usage.
The other result is an improved attack on a reduced version of AES, the widely used encryption standard. Full AES-128 has 10 rounds; Claude attacked a deliberately weakened seven-round version studied by cryptographers and made the previous best attacks 200 to 800 times faster.
To be clear, neither result breaks any production system. HAWK is a candidate standard and is not deployed, while the AES result does not work against full AES. This is cryptography research functioning normally: Researchers publish algorithms, other researchers try to break them, and the survivors become standards.
The new thing is that one of the researchers can spend 60 hours reading the literature, doing mathematical experiments, coordinating with copies of itself and finding a flaw that human experts missed. For about $100,000. Traditionally the security of a cryptographic system meant that sufficiently motivated attackers could not break it with available mathematics and computing power. Now "available computing power" includes a model that does a week of cryptography research on demand.
This is good for cryptography, probably. Before deploying a new encryption standard, you can pay an AI model to attack it. If the model breaks it, you discard it and build a stronger one. If the model does not break it, you have learned that it can withstand at least $100,000 of API credits. Cryptographic security levels used to be expressed in bits. Increasingly there will also be a token budget.
Artificial intelligence is better at arguing than world championship debaters, with an important caveat: It is allowed to talk more.
A new paper reports four preregistered experiments covering 18,978 conversations with 6,923 people. The researchers pitted AI systems against laypeople, professional canvassers, winners of a persuasion tournament and world championship debaters. The humans could choose their issues, research them, practice for hours and compete for £1,000 bonuses. The AI systems were still "reliably more persuasive than expert humans."
They were also nearly three times as effective as professional canvassers at generating real donations to Save the Children. So this is not just a benchmark where the model persuades a grader that a fictional sandwich is technically a vehicle. It got people to send money.
Why? The paper found "converging evidence that AI's advantage stemmed from rapidly deploying larger quantities of information." After coaching, expert humans could tie an AI system when it was constrained to answer at human speed and with human-length messages.
This is reassuring in one sense. The models have not necessarily discovered magical mind control. They are just able to retrieve and type relevant arguments faster than a person can. If you make the computer communicate like a human, the best humans can keep up.
On the other hand, computers do not generally communicate like humans. The commercial advantage of a computer is precisely that it can answer instantly, forever, at negligible marginal effort. "AI is only more persuasive because it can produce more persuasive material more quickly" is a bit like saying that a calculator is only better at arithmetic because it can calculate faster. Yes. That is what the concern was.
The traditional political campaign hires canvassers, trains them, sends them door to door and hopes they remember the talking points. The AI campaign can send every voter a tireless world-class debater who knows all the talking points, adapts in real time and never needs a bathroom break. If you want humans to remain competitive, apparently the regulation is not "ban superhuman persuasion." It is "make the robots type with two thumbs."
