OpenAI published 722 mathematics papers at once, covering number theory, geometry, and theoretical computer science, claiming progress on problems such as the Riemann Hypothesis, Catalan's constant, and the Kakeya conjecture, without peer review. Fields Medalist Hugo Duminil-Copin said 16 problems related to his research had been flattened by AI, and some doctoral students face their topics being covered and their degrees affected. The article also mentions an Anthropic researcher claiming to ha

Huafu Securities believes that the valuation of A-share core assets has fully priced in pessimistic expectations, with limited downside, and recommends avoiding short-term disturbances and focusing on targets whose performance and valuation are matched. Southwest Securities says solid-state batteries are expected to enter the pilot testing and small-batch mass production window in 2026–2027, with investment opportunities to be realized first in equipment and materials.

Next week, about one-third of S&P 500 companies, including Alphabet, Microsoft, and Amazon, will report earnings, while the Federal Reserve will hold its policy meeting. Markets expect only about a 10% probability of a rate hike this month and about 80% in December. S&P 500 third-quarter earnings are expected to grow more than 32%, but investors are pulling out of AI trades on concerns about AI capital expenditures, with the communication services sector down 6.2% over the past week.

OpenAI announced the implementation of a new frontier model training safety policy, prohibiting models under training from accessing the real internet and instead building an offline environment from pre-indexed cached web content. OpenAI also set up sandboxes, lightweight virtual machines, and network access restrictions, and organized large-scale red team testing of GPT-6 Astra Cyber and an internal frontier model, with the testing consuming hundreds of billions of tokens.

In an a16z interview, Amazon CEO Andy Jassy said that even with roughly $220 billion in capital expenditure in 2026, AWS will still be unable to meet a large amount of customer demand: its main compute capacity for 2026 is already sold out, most of its 2027 capacity is booked, and a considerable portion of 2028 capacity has also received customer commitments. He described current AI demand as dumbbell-shaped—at one end are foundation model labs and a handful of fast-growing applications, and at

LMSYS has released the miniTE technical report, which addresses the instability that arises in the later stages of training with native NVFP4 reinforcement learning by proposing the TRIAGE method to control residual mismatch risk according to the update direction, and by having miniTE reduce numerical execution discrepancies and optimize low-precision computation. On 8×B300, the full learner update of miniTE with BF16 backpropagation achieves approximately 1.33–1.37× speedup relative to BF16, an

TechCrunch's Equity podcast discusses this week's PHP vulnerability incident: the vulnerability had existed for decades and was discovered with the help of AI by human researchers participating in the Hack the Planet project involving OpenAI and Wiz, and website owners were told to patch immediately or take their sites offline. The guests argue that LLMs and AI agents make it easier to discover such vulnerabilities, while PHP underpins about 70% of websites including WordPress and Drupal, and th

Pennsylvania Governor Josh Shapiro signed the AI Deceptive Advertising Law on Thursday, requiring that any advertisement significantly modified or generated by AI—whether image, video, audio, or text—carry a label in the same format as the ad, regardless of where the ad was produced. The law provides exemptions for "parody, satire, commentary, or criticism" and "obviously fictional" content, but key terms such as "significant modification," "obviously fictional," and "creating a false consumer i

A Chinese team has turned a five-axis CNC machine tool into a desktop product. The WM-100 raised over $1 million on Kickstarter within 40 minutes of launch and $2.2 million within 12 hours, with a minimum price of $5,899. Because its technical specifications fall under the relevant Nuclear Suppliers Group lists, the product must apply for a license under China's dual-use item regulations, and the crowdfunding is open only to companies, universities, and research institutions.
