Character.AI recently filed for bankruptcy protection and may cease operations if no viable sale plan emerges; the company, valued at $1 billion in 2023 with monthly active users once around 28 million, spent about $56.1 million on compute from January to August 2026 and still loses about $8 million to $9 million per month. The article argues that the free version already meets core needs and that emotional companionship is hard to convert into willingness to pay, while the more conversations there are, the higher the inference costs; together with minor safety and regulatory requirements such as China's Interim Measures for the Administration of Anthropomorphic AI Interaction Services, these factors are squeezing the space for such products. The article also compares transformation attempts such as Maoxiang's monetization through interactive storylines, membership fees plus virtual top-ups, Zeta's shift to story-led experiences, and Linky's addition of a gacha mechanic.
Why read thisThis article breaks down the structural dilemmas of AI companion apps from three angles—users' willingness to pay, inference costs, and regulation—and compares transformation paths such as Maoxiang and Zeta.

On the evening of October 31, the DeepSeek Harness team released "Super-agent Design Exploration: Toward a More Autonomous Agent System," proposing the Super Agent concept and open-sourcing the prototype dsh-superagent-prototype on GitHub. The article splits tasks between two roles, Router and Worker, triggers work from activity such as group chats, emails, and code checks through two filters—rules plus a model—and emphasizes notifying only when results are usable or a human decision is needed. The team says the prototype is only a research prototype, not a formal product; it currently mainly targets one GitHub repository and can also connect to Feishu, and some designs have not yet been implemented.
Why read thisThe DeepSeek Harness team lays out the Router/Worker division of labor, trigger, and attention cost design of Super Agent, with an open-source prototype attached.
Parameter Labs disclosed an attack chain targeting the ChatGPT HTML preview (formerly Canvas) sandbox. An attacker can craft a share link that, when visited by another logged-in user, steals private data or performs actions on their behalf. The attack starts with the postMessage-receiving code of the MathLive virtual keyboard using innerHTML, injects an iframe without sandbox restrictions, and then uses the YouTube oEmbed endpoint allowed by CSP to reflect and execute JavaScript. OpenAI has fixed the vulnerability and paid a $5,000 bounty.
Why read thisThe original text fully reconstructs an attack chain from a sandboxed iframe to reading users' private data, which helps understand the isolation boundary of HTML preview-type features.

Tomasz Tunguz analyzes the $1 trillion revenue targets separately proposed by Andy Jassy and Elon Musk. Extrapolating at current growth rates with 15% annual decay, Google Cloud and SpaceX will reach $250 billion in quarterly revenue ($1 trillion annualized) in 2030, with AWS following in 2032. He notes that the market has sold off some cloud providers out of concern that cash flow from legacy businesses cannot sustain capital expenditures; Google's search advertising growth has already slowed from 19% in Q1 to 12% in Q3, and AI Mode's monetization rate is lower than that of traditional search. Microsoft is the only hyperscaler to boost ARPU through AI faster than seat growth slows, while ServiceNow's market value has fallen 29% on concerns that its seat-based business will be eroded by AI.
Why read thisThe article uses quarterly data from four cloud providers to project a path to trillion-dollar revenue, and points out that the erosion of legacy cash cows by AI is the key variable for crossing the chasm.
The Axiom team used the multi-agent system AxiomProver to formalize the approximately 15,000-page proof of the classification theorem of finite simple groups (CFSG) into Lean code within 24 days, producing a 43.1-million-line codebase. During the process, the AI recorded hundreds of anomalies, 34 of which were major logical deviations, including a key closure assertion in John Walter's 1986 paper that does not hold, for which the AI provided the counterexample PSL₂(49). The team then contacted group theorists Richard Lyons and Ronald Solomon, and AxiomProver proved a new theorem, Preservation of simple tops, to fill the gap.
Why read thisAxiom used a multi-agent system to formalize the classification theorem of finite simple groups in 24 days and pointed out logical gaps in the original proof, allowing readers to understand the concrete path by which AI participates in mathematical verification.
AMD announced an all-stock acquisition of World Labs, founded by Fei-Fei Li, for approximately $8.2 billion. After the deal closes, Fei-Fei Li will serve as AMD Executive Vice President and Chief Scientist, reporting directly to Lisa Su, and World Labs' roughly 70-person team will be integrated as a relatively independent research unit. The article reviews Fei-Fei Li's three directional choices—from ImageNet, to AI democratization, to spatial intelligence—and notes that this acquisition is about 52% higher than World Labs' $5.4 billion valuation after its February 2026 Series C funding round. The author believes that what comes next is whether the performance gains of Atlas and Marble on MI450 can continue the curve of the 4x speedup on MI325X, and whether other spatial intelligence teams will consequently shift to AMD hardware.
Why read thisThe article reviews Fei-Fei Li's three directional choices from ImageNet to World Labs, and lays out two concrete criteria for judging whether spatial intelligence succeeds following the AMD acquisition.

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.
