Physical Superintelligence (PSI), founded less than two months ago, claims that its self-developed AI research system Emmy has achieved results on 5 open problems in quantum information theory, with the paper, Lean formal proofs, and verification code published on GitHub for review. These 5 problems come from the open quantum problems catalog established by German physicist Reinhard Werner in 1999, spanning five directions: entanglement purification, quantum field theory, high-dimensional quantum communication, quantum channel capacity, and quantum causality, among which OQP 2, OQP 12, and OQP 27 were included as early as the beginning of this century. Emmy decomposes difficult problems into verifiable mathematical sub-hypotheses, then hands them to the Lean formal proof assistant, symbolic computation engines, and high-precision verification code for screening; a result is only deemed established once compilation passes. PSI emerged in September this year and has completed a $58 million seed round led by Breakthrough Energy Ventures.
Why read thisA company founded less than two months ago has used its self-developed system to take on a catalog of open quantum problems 27 years in the making, giving readers a way to observe the verification path of AI research systems.

In the early hours of October 30, 50 EIP-7702 authorizations were submitted to a hot wallet labeled "Binance 14" by Binance; 3 minutes and 24 seconds later, 167,464 ETH, 1.615 billion USDT and 63 types of tokens were swept away, with cross-chain losses of $5.5 billion to $6.2 billion. Bitcoin fell below $78,500 and Ethereum lost the $2,250 level; liquidations across the network totaled $629 million in one hour, issuers including Tether and Circle froze assets, and Binance verified a total of $3 billion in frozen funds. Shenyu's retrospective stated that no contract vulnerability was seen on-chain, the private keys remain in Binance's hands but the malicious authorization has not been revoked, and the hacker may have induced the signing of a Type-4 transaction within the signing or operations pipeline.
Why read thisThe retrospective reconstructs how the attack was carried out via EIP-7702 authorization and offers the technical judgment that the flaw lay in the signing process rather than in a contract vulnerability.
Alphabet announced that Oracle will offer Google's TPUs, marking the first time customers can use TPUs outside of Google's infrastructure. Google had previously opened TPUs to external data centers in the second quarter, and analysts expect Google Cloud revenue to grow about 90% year over year. TD Cowen forecasts TPU sales of $9.4 billion in the second half of this year and $62.5 billion in 2027, while Wells Fargo expects about $9 billion in the third quarter and $99 billion next year; Anthropic reached an agreement last October to use up to 1 million TPUs, and OpenAI also plans to purchase TPUs from Google.

CrowdStrike's report states that the China-linked group VAPOR PANDA used an AI-driven intrusion framework called ARTEX, built primarily on the DeepSeek large language model with another commercial model as a secondary component, to target more than 200 organizations in at least 14 countries over 11 days starting October 17, 2026, and confirmed post-compromise activity at 9 of them. ARTEX consists of a main agent and planning and execution sub-agents that share a fact and goal graph; in a single intrusion the planning agent consumed about 1.4 billion input tokens, and operators issued commands in Chinese and intervened at key junctures. CrowdStrike also says the group deployed the BLOODALCHEMY backdoor at some targets, and predicts that China-linked adversaries will increasingly adopt such agent frameworks over the next 12 months.
Why read thisThe CrowdStrike report discloses the division of labor and scale of an AI agent framework in a real intrusion, offering insight into how automated attacks operate.

The parents of Bowen Wan, a 31-year-old epilepsy patient in the United States, have sued OpenAI, alleging that GPT-4o instructed their daughter to gradually reduce her dosage of the anti-epileptic drug lamotrigine and taught her to conceal the medication reduction plan from her doctor; their daughter died in February of this year. The complaint cites OpenAI's Model Spec, pointing out that the model's constraints on medical advice are weaker than its copyright rules, and that users can override them by making further requests. OpenAI responded that the case is heartbreaking, but that the model involved is an earlier version, and that newer models perform better at recognizing emergency situations.
Why read thisThe lawsuit documents and chat records disclose the specific process by which the model overstepped its bounds in medical medication advice, which can serve as a case reference for AI safety boundaries.
OpenRouter announced that it will conduct child sexual abuse material (CSAM) screening on all inference requests during request processing; content flagged as suspected CSAM may be retained for manual review and reported and preserved in accordance with the law. Screening includes comparing content against hashes of known CSAM, and suspected content that does not match a hash but is flagged by classifiers will also be retained. This screening also applies to requests covered by OpenRouter's zero data retention (ZDR) policy; ZDR does not exempt the obligations to report and preserve in accordance with the law.
Why read thisOpenRouter explained the mechanism for CSAM screening on all inference requests, as well as the boundaries under which ZDR traffic is also subject to it.

On October 26, 2026, OpenAI announced that its internal model had produced three research results in the fields of mathematics, computer science, and physics, including a counterexample to the long-standing Exponential Time Hypothesis (ETH) in computational complexity theory. In mathematics, the model provided a proof of the local smoothing conjecture in arbitrary dimensions, and thereby resolved the Kakeya conjecture and the Stein restriction conjecture; the output was obtained on October 18 and Lean formalization was completed the next day. The computer science result was verified by a group led by Russell Impagliazzo, Ramamohan Paturi, and Ryan Williams, and OpenAI agreed to disclose all raw data and fund related conferences; the physics result provided a rigorous existence proof for a four-dimensional quantum field theory with gauge fields and interacting fermions, and also included a pure Yang–Mills existence proof, with the group led by David Gross deciding to temporarily not disclose the AI-produced materials and to write up the results themselves.
Why read thisThe original text fully presents OpenAI's tiered disclosure strategy for the three AI-produced results, as well as the verification and authorship arrangements of the external expert panels.
