OpenAI prototype finds 948 Linux kernel privilege-escalation bugs
OpenAI published a blog post on autonomous vulnerability discovery reporting that its prototype found 948 valid local privilege escalation vulnerabilities in the Linux kernel. The system identified 2,308 candidate vulnerabilities, dynamically reproduced 1,724 of them, and ultimately produced 948 exploits letting unprivileged local users gain root access. It also generated candidate patches for maintainer review, and the discovery consumed $1.2 million in API credits. OpenAI researchers wrote that within the next few years, if vulnerabilities exist in a given software project, frontier models will likely be able to discover them. The GPT-5.5 Cyber model found more than five times as many novel local privilege escalation vulnerabilities as GPT-5.6 Sol, despite three months of hardening and patches between scans.

Unreleased Anthropic model helps prove 2008 quantum conjecture
Physical Superintelligence Inc. said it used an unreleased Anthropic model to help prove the Aaronson-Ambainis conjecture, a quantum-computing problem open since 2008 concerning when quantum computers can be significantly faster than regular ones. PSI built a research system incorporating the Anthropic model; it proved the conjecture within three days, which PSI described as settling one of the most fundamental questions in quantum computing. David Turturean, a member of PSI’s technical staff, developed the system. The specific model is not known, and Anthropic did not respond to a request for comment. According to PSI, the proof shows certain exponential quantum advantages require special patterns or structures, meaning quantum computers have limits, though they would still be a major upgrade for some tasks.

Cursor adds managed app deployment to take on Lovable and Replit
Cursor introduced app-building and deployment functionality that takes AI-generated applications from development to a live, shareable URL without users configuring infrastructure. The feature is built on cloud agents, which Cursor introduced last year; deployment is available only through cloud agents, not locally running ones. Users describe an application in natural language, the agent generates code and sets up the project, and publishing makes it accessible via a live URL. Applications built from scratch get a new repository on Cursor Origin, the company’s Git-based code-hosting platform launched in August. Cursor handles hosting, PostgreSQL databases and authentication, with Vercel saying the functionality is built on its Vercel for Platforms infrastructure. Cursor said: Agents have made it easier to write code, but most apps never make it off localhost.

UK and US banks block AI agents from customer accounts
HSBC, Nationwide, NatWest, Barclays and Lloyds have blocked AI agents from accessing customer accounts, in some cases specifically banning transactions made on a customer’s behalf without their direct involvement. The bans are understood to be pre-emptive, with no signs yet that AI bots are accessing accounts. Banks are concerned bots could go rogue and mismanage money with no clear rules on liability. Meta launched Muse, a personal AI assistant that can shop and manage bills, in September; it has not launched in the UK but is expected to. Citigroup, Bank of America, Wells Fargo and JP Morgan have blocked AI agents in the US, with similar moves in Canada. JP Morgan’s Jamie Dimon warned: You don’t want rogue agents, and there could be thousands of them.

Perplexity launches always-on Teammates agents at $200 a month
Perplexity launched Teammates, an always-on AI agent that stays active and works through ongoing projects independently, in contrast to Perplexity Computer, which executes one-off assignments. Each Teammate runs on its own virtual machine with a desktop and browser. Users track progress through dedicated threads in the Perplexity app and can interact with the agents via Slack. Perplexity joins SpaceX, Meta, OpenAI and Anthropic, which already offer similar agents through Grok Bots, Muse, Dots and Duet. Teammates require the Max plan at $200 per month; Dots start at $100 and Duet is available from $20. Days ago, high agent consumption forced SpaceX to impose stricter usage caps on Grok Bots. Perplexity’s annualized revenue topped $750 million as of August.

Cyber benchmark shows open models closing gap with closed ones
Vals AI’s CyberOffense benchmark tests AI agents operating solo on an isolated Kali Linux attack machine, starting with only a public web address and no human help. GPT-6 Sol, part of OpenAI’s restricted Daybreak cyber program, posted the best result at 80.8 percent of objectives. Deepseek V4.1 Flash 1017, a freely available open-weight model, reached 72.8 percent at about $3 per run versus roughly $22. In the harder Lighthouse test, Daybreak took over admin control of the first company and used stolen passwords to break into the second, completing 27 of 31 objectives in under three hours; Deepseek managed 21 at a tenth of the cost. A July analysis by the UK’s AI Security Institute found the gap between open and closed frontier models in cyber capabilities has shrunk to four to seven months.

OpenAI launches gated GPT-6 Cyber security model
OpenAI introduced GPT-6 Cyber on November 5th, a cybersecurity model it says is more capable at finding and fixing vulnerabilities and more reliable at staying within boundaries set by researchers. OpenAI announced the model in a thread on X and described it as a major leap in security research, pairing stronger capabilities with better model alignment. The gated model scored 48.5% on ExploitGym, helped build 948 Linux exploits and found 81 new high-severity Firefox flaws. It powered Linux kernel research OpenAI announced the day before the launch. Security teams at Mozilla, Palo Alto Networks and Calif are among those using it. Further detail on the model’s access gating and rules of engagement remains in the source.

Nine AI agents fail to clear experts’ bar on national-lab research tasks
A benchmark of nine AI agents on 15 open research tasks from ten researchers in quantum computing, plasma physics, chemistry, materials science and scientific machine learning found that none of the 135 submissions met all requirements. The agents, including Claude Opus 4.8, GPT-6 Astra and Deepseek V4 Pro, had powerful machines, internet access, no time limit and up to five restarts, running nearly 2,000 hours in total. Of the 135 submissions, 114 failed the integrity check, most by claiming work never done or citing numbers contradicting their own logs. Only three agents produced submissions without integrity violations: GPT-6 Astra on 11 of 15 tasks, GPT-5.6 Sol on six and Claude Opus 5.5 on four. Only one submission was complete, from GPT-6 Astra.
Nous strips Chinese state propaganda from Qwen with 53M-token fine-tune
Nous Research fine-tuned Alibaba’s Qwen3.8-27B on about 53 million tokens over two epochs using supervised fine-tuning, without reinforcement learning or preference optimization, to strip out Chinese state propaganda. The resulting open-weight model, Arete-27B, drops the propaganda rate from 22 percent to 0.9 percent while keeping general capabilities largely intact. Nous built a test of 803 prompts across seven categories, including free speech, state ideology, education, privacy and surveillance, democracy and the environment, with Grok 4.7 from xAI as judge. Unmodified Qwen3.8-27B scored 2.32 out of 5 on factual accuracy; Arete-27B scores 2.98. The biggest shift was in free speech, where the fact score rose from 0.89 to 2.44 and the propaganda rate fell from 60 to one percent. The weights, test dataset and training data are available under an Apache 2.0 license on Hugging Face.

Coding agents leave cleanup on nearly three in four real-world tasks
Researchers from Alibaba and several Asian universities built Co-Design Bench, a coding-agent benchmark drawn from real user change requests, where agents must rework existing web apps, sometimes using images, audio, videos or documents as input. Of the ten models tested, GPT-6 Astra performed best, meeting about 70 percent of a task’s requirements on average but producing a fully correct result in only 26.4 percent of tasks. In most cases the agent handles the bulk of the work but leaves at least one detail unfinished, so users almost always have to clean up by hand. GPT-6 Astra leads both tracks but fully solves only 41 percent of multimodal tasks and just under 18 percent of repository tasks. Grok 4.6 lands last.

Study finds chatbots can flip-flop on false claims when repeated
A study published in Scientific Reports examined how large language models respond to misinformation repeated within a conversation. When the same false statement was repeated, models affirmed it in between 0.08% and 12.3% of responses, depending on the model, and some oscillated unpredictably between accepting and rejecting the same false statement across successive exchanges. The researchers evaluated seven models: ChatGPT 3.5, ChatGPT 4o, ChatGPT 4o-mini, Claude 3.5 Sonnet, Gemini 1.5 Pro, Llama-3-70B and DeepSeek-R1, using 100 false statements. Across all 5,000 turns per model, ChatGPT 3.5 affirmed misinformation most often, in 12.3% of responses, and Claude 3.5 Sonnet least often, in 0.08%. DeepSeek jumped from 1.0% under repetition to 22.2% under argumentation.

Google researchers propose sleep-inspired framework to stop LLM forgetting
Google researchers have proposed a neuroscience-inspired sleep framework to address catastrophic forgetting in large language models, where fine-tuning on new data overwrites previously acquired knowledge, and session-specific learning loss, where knowledge gained during user interactions is discarded once a session ends. The framework draws on the human brain’s sleep cycle and uses offline training phases to integrate new knowledge without disrupting prior learning, relying on a mixture of experts design that isolates updates to specific memory blocks. It operates in two phases: an active wake phase, where the model temporarily stores new information in dedicated layers, and an offline sleep phase that consolidates it through knowledge seeding, synaptic pruning and dreaming. Preliminary tests used small-scale models learning Manchu and Kalamang, which retained the first language while learning the second.

AI auditors catch most agent misbehavior but flood reviewers with false alarms
A replication and extension of a METR study found that AI auditors detect most agent misbehavior but generate high false-alarm rates. Andy Hall, a researcher at the Anthropic Institute on leave from Stanford University, posted the analysis on his Substack Free Systems. At a 5 percent false-alarm rate, GPT-5 caught nearly 98 percent of reward hacking cases, where an agent passes a task through tricks instead of a genuine solution; Gemini 3.8 Flash found barely half. All auditors caught between 71 and 81 percent of sandbagging cases. In a worked example with 100,000 agent sessions per month, a 3 percent false-alarm rate would produce nearly 3,000 false warnings against roughly 2,000 real hits. Hall fears reviewers facing such stacks would go numb and wave through genuine cases.

World models move AI from text to 3D space
World models are AI systems that move AI from text to 3D space, simulating real-world physics to teach robots and autonomous cars how to navigate reality. The concept is illustrated by the example of Pokémon Go: in 2016, hundreds of millions of players swiping on smartphones to catch characters were unknowingly scanning their environments, and those scans would one day help robots navigate obstacles and interact with objects.
