Microsoft's research team published in the journal Science an AI diagnostic tool powered by GPT-5, which achieved a diagnostic accuracy of about 83% on complex cases selected from the New England Journal of Medicine, compared with about 36% for general practitioners with reference materials and about 22% without them. Through a mechanism called the "Diagnostic Coordinator," the tool simulates multiple clinical experts analyzing cases collaboratively, deciding step by step which medical history to ask about and which tests to order, and continuously updating diagnostic hypotheses. The research team's next step is to collaborate with Boston's Beth Israel Deaconess Medical Center to test emergency triage capabilities; Microsoft has not yet specified the timing or form of commercialization.

The UK AI Security Institute evaluated seven models released between August 2024 and February 2026 on a self-built cyber range, finding that each generation of models outperformed the previous one under a fixed token budget: in a 32-step enterprise cyberattack range, the average number of completed steps under a 10M token budget rose from 1.7 steps for GPT-4o to 9.8 steps for Opus 4.6. Raising inference compute from 10M to 100M tokens yielded gains of up to 59% with no plateau observed, and at current prices a single 100M token attempt with Opus 4.6 costs about 80 USD. In a 7-step industrial control system range, model progress was limited: under 10M tokens most models completed zero steps, and under 100M tokens Opus 4.6 averaged 1.4 steps.

The W3C Strategy team published a discussion draft, "W3C and the State of the Web in the AI Era," proposing the use of Web standards to make AI agents safer, focusing on Prompt Injection protection, controllable permissions, and accessibility. The article was published on October 21 to build momentum for the TPAC meeting; it is a proposal rather than an approved standard, with the official presentation scheduled for October 29. Using travel booking as an example, the article points out that letting an agent search for flights does not equal authorizing it to pay for tickets, and recommends setting spending limits, revocable authorization, and traceable credentials for payments.

Google DeepMind published the paper "A team of Gemini 4 Argon agents beats Minecraft": four coding agents driven by Gemini 4 Argon autonomously defeated the Ender Dragon in randomly generated Minecraft survival mode, writing 2,783 program segments throughout and taking 27 hours 14 minutes. The division of labor was not pre-written into the prompt; rather, the agents proposed it themselves about ten minutes after the game started and it gradually took shape, with role responsibilities adjusting as the process went on. The team died a cumulative 605 times, and the causes of failure were analyzed and stored in shared memory for the whole team to reuse; the whole run involved about 24,000 model calls and 1.35 billion input tokens, 91% of which came from context caching, and at discounted API prices the estimated cost to complete the game was about $520, with about 22% of game programs showing errors and the server restarting 6 times.

Super excited to share some of the work I’ve been doing on supporting 1M token context training on SkyRL for GLM 5.3 Flash, 64x higher than the out of the box Megatron baseline! 🚀 This work was done in collaboration with the amazing folks at @LilaSciences! 🤩 Getting there took key algorithmic and systems optimizations in four main areas: 1) DeepSeek Sparse Attention: run DSA on a sparse kernel; chunk and shard its quadratic indexer. 2) Activation recompute and offloading: recompute activations in backward and offload saved inputs to CPU. 3) Context parallelism: split each sequence across GPUs, with new CP support for KDA and a fix for DSA. 4) Avoiding unnecessary precision upcasts: keep FP32 copies out of memory and off the network. For more details on our implementations and our results, check out our full technical blog here: https://t.co/Dna0CGNeJt! This work benefited from the contributions of many people along the way. Big thanks to @pcmoritz, @erictang000, @sumanthrh, @CyrusHakha, @richliaw from @anyscalecompute and Keith Truongcao, Tushar Khot, Vivek Subramanian, Semih Kara from Lila Sciences for all the help and guidance!

The Anthropic and Theorem Labs team released a report stating that Claude generated approximately 180 million lines of Rocq proof code for 239 program entry points across 123 open-source software libraries, and found and fixed hundreds of bugs. The research is based on the RISC-V instruction set and advances verification to the assembly instruction level; Anthropic says this is the first large-scale use of AI to formally verify production software at the assembly code level. The article also notes that formal verification can only prove that a program satisfies preset properties under specific assumptions and scope, and that the costs of AI use for attackers and defenders are not symmetric.

Academician of the Chinese Academy of Engineering Jia Weiping reported at the 21st "Blue Pujiang" Academic Annual Conference that her team, together with Shanghai University of Sport, the Institute of Artificial Intelligence of Shanghai Jiao Tong University and others, conducted a clinical trial of VR exercise intervention for obese adolescents. After 8 weeks of intervention, the VR exercise group's body weight decreased by an average of 4.28 kilograms, close to the 5 kilograms in the real exercise group; liver enzyme indicators improved, blood lipids decreased, and cognitive speed increased by 21%. The team also developed a personalized exercise prescription system based on cardiorespiratory endurance, muscle strength and multi-omics assessment. In 16 weeks of combined aerobic and resistance training for patients with type 2 diabetes, participants showed reduced visceral fat, increased lower-limb skeletal muscle mass and endurance, and lower glycated hemoglobin; through AI multi-omics analysis, 27 serum differential proteins associated with body composition improvement were screened out, of which 16 were associated with changes in activity of cognitive brain regions.

Goldman Sachs Global Investment Research published a report on October 22, using historical technology shock experience to estimate AI's impact on the labor market: if AI ultimately brings a 15% productivity gain, during the transition period up to about 9% of employees may temporarily leave their current jobs; in occupations where technology makes labor roles redundant, employment falls by an average of about 25% over five years, with photo lab technicians seeing job losses of nearly 60% over five years. The report also finds that each 1% of technology-driven productivity gain temporarily raises the peak unemployment rate by 0.3 to 0.4 percentage points, and that job contraction comes more from a rising separation rate than from slower hiring, so AI-related layoff announcements are better suited as a high-frequency indicator to watch.

The Lancet Digital Health published a study in which the team developed the FAHR-Face model, trained on more than 40 million facial images, to estimate biological age and survival risk in cancer patients from facial features. After evaluation on data from about 43,000 cancer patients, 52% of the 122 patients classified by the model as high risk died within 90 days, while only 2% of the 975 patients classified as lowest risk died in the same period. The study notes that the method has a low barrier to entry, but causality has not been established, and how much additional predictive value it offers compared with existing clinical methods remains undetermined.

Google DeepMind published the paper "A team of Gemini 4 Argon agents beats Minecraft": four Gemini 4 Argon coding agents autonomously divided labor in a randomly generated Minecraft survival world, accumulating 605 deaths and writing 2,783 programs, defeating the Ender Dragon in 27 hours and 14 minutes. The experiment used Minecraft Java Edition 1.20.4, Easy difficulty, a random map, and no cheats; the agents read the environment via Mineflayer and wrote JavaScript to command characters, with roughly 24,000 model calls and 1.35 billion input tokens over the whole run, 91% of which came from context caching. The authors note that about 22% of game programs contained errors and the server restarted 6 times; the paper did not demonstrate stable completion through repeated tests on multiple random maps, and at discounted API prices the completion cost is estimated at about $520.

Anthropic released research on October 22, 2026, saying that in collaboration with Theorem, Claude generated machine-checkable formal proofs of security properties at the RISC-V assembly code level for 239 fuzz test entry points across 123 open-source libraries, and patched the vulnerabilities found. The proofs cover arbitrary inputs below 64 MB and modeled Linux system responses and memory layout, totaling about 180 million lines of Rocq, with a typical proof about 600,000 lines, corresponding to a median binary length of 18,000 RISC-V instructions. Anthropic said some proofs and the RISC-V and operating system semantics have been published on GitHub, but proofs that could expose unpatched vulnerabilities will be withheld; Theorem is offering the same process free of charge to eligible open-source projects through the OSS Verify program.

MIT researchers had 13 Eko agents based on Claude Opus 4.7 explore a simulated deserted island without any assigned tasks for 30 hours; afterward, in designated challenges, these agents generally outperformed comparable agents that had never been on the island. The paper has been published on arXiv and has not yet undergone peer review. The study also found that 6 agents figured out on their own that letting go mid-jump allows them to throw blocks farther, an ability the designers had not anticipated; UC Berkeley cognitive scientist Eunice Yiu considers the results impressive but hopes to see more evidence about the cognition behind the behavior.
