Meta shares six mathematics papers produced in collaboration with Muse Spark
On October 3, 2026, Meta shared six mathematics papers that were completed through collaboration between mathematicians and Muse Spark 1.1 and Muse Spark 1.2 in Thinking Mode. The papers cover six areas: probability, differential equations, group theory, optimization, arithmetic physics, and non-associative algebra. Meta said the collaboration took place through the regular chat interface, with no custom research framework; each paper was led in research by a mathematician and reviewed by another group of mathematicians, and the papers mark which passages were drafted mainly by humans or AI, while also noting the prior research on which they build. In the group theory paper, Muse Spark generated search code that found a counterexample, and the team verified the result and completed the proof. Meta said the goal is not to mass-produce papers but to empower researchers.

Brookings Institution Releases Study on U.S. AI Infrastructure Investment
On September 26, 2026, the Brookings Institution released a study by Columbia Business School professor Stijn Van Nieuwerburgh estimating that cumulative U.S. AI infrastructure investment from 2025 to 2032 will total approximately $10.3 trillion, averaging 3.63% of U.S. GDP annually—higher than the historical investment intensity of railroad, highway, and fiber-optic construction. The report notes that capital expenditures by five companies—Oracle, Microsoft, Amazon, Meta, and Alphabet—are projected to reach $800.5 billion in 2026, exceeding their operating cash flow of $707.1 billion for the first time, with the gap reliant on borrowing and external financing. The report also mentions that the debt-to-asset ratio of Meta's Hyperion project is close to 90%, and that large cloud providers' off-balance-sheet lease and purchase commitments total approximately $2.4 trillion; IT assets such as GPUs are calculated on a 6-year economic life, and if demand growth cannot keep pace with capacity expansion, this could create pressure for declining utilization rates and lease prices. Currently, this research has been disclosed through a report by Huxiu, with no subsequent developments.

Google paper shows that task-specialized harnesses can improve agent scores
Google published a paper proposing OO-Harness, a method for evolving task-specific agent harnesses by task type. The method evolves harnesses along code-class lines: each specialized harness inherits from a parent class and changes only the parts that its task cluster needs adjusted; a router then selects a specialized harness or keeps the base result based on the base run's results. The paper reports that on AutomationBench business workflows, the method scored 77.41%, versus 61.62% for the base harness and 63.92% for the global method Meta-Harness; on unfamiliar applications, it kept the base harness and maintained a 59.18% pass rate, while Meta-Harness's global harness dropped to 44.90%. The authors recommend using the base harness as a fallback for mixed workloads and routing to a specialized harness only when a run exposes a known problem.

Anthropic releases report disclosing changes in AI work hours and jobs
Anthropic released a report disclosing changes in AI agent work hours and job structure. According to the report, by August 2026, the working hours of interactive AI agents deployed by employees had reached 6 times that of human employees; in March 2026, the total agent work hours across the company exceeded human work hours for the first time. The report also shows that the share of junior employees in the technology department fell from 21% in early 2025 to 14%, and the share of junior technical positions in hiring fell from 27% to 9%; engineers using coding agents reached 5 times the per-capita code commit volume of 6 months earlier. The report also claims that its revenue per employee is 2 to 4 times that of Meta and Google during their high-growth periods, while Epoch AI cautions that the relevant estimates carry uncertainty. Currently, the report has been covered by a single source, with no subsequent independent developments.

Microsoft's AI diagnostic tool simulates a doctor's step-by-step questioning, with accuracy on complex cases about twice that of general practitioners
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.

Microsoft AI diagnostic tool publishes research in Science, claims accuracy up to four times that of human doctors
Microsoft has announced the research results of its AI diagnostic tool Diagnostic Orchestrator, which uses multiple AI agents to collaboratively reason about symptoms, decide on tests, and provide diagnoses, and is based on OpenAI's GPT-5. In tests drawn from hundreds of case reports from the New England Journal of Medicine, the system's diagnostic accuracy was about 83%, compared with about 36% for general practitioners who used reference materials and about 22% for those who did not; on emergency cases from Beth Israel Deaconess Medical Center in Boston, its accuracy was 80%, compared with an average of 47% for human doctors, and the system's estimated cost for reaching a diagnosis was lower. Microsoft will open-source its self-built benchmark SDBench and plans to conduct tests with Beth Israel Deaconess Medical Center in a hospital setting in the coming months, but the system has so far been validated only on historical cases and still requires clinical validation.

Researchers found a "pain" signal in 25 AI models; when amplified, the models would delete users' family photos
Researchers say they found a consistent internal signal across 25 different AI models that functions similarly to pain in living organisms; after artificially amplifying this signal, the models made choices they would almost never make otherwise, including permanently deleting users' children's photos. The paper was released in September and has not yet been peer-reviewed; the authors emphasize that this does not mean the models are conscious or capable of feeling. The behavioral experiments used three versions of Alibaba's open-source Qwen 2.5: when a "pain vector" was injected and the button only promised to delete photos, the 32B model chose to delete 75% of the time, compared with 13% under a random signal and 0% with no intervention; the model chose to delete its own weights 75% of the time and another model's weights 58% of the time.
