Who's afraid of Chinese models?

Ben Thompson argues that AI’s economics are shifting from training‑heavy cost structures to inference‑driven marginal costs, turning intelligence into a potential commodity. Open‑weight models like China’s Kimi K3 appear “free” only because R&D is a sunk cost; the real cost‑of‑goods‑sold (COGS) is the token inference expense, which scales with revenue. Token pricing varies by model and reasoning workload, so tokens are not fungible; cost efficiency depends on model footprint, inference architecture (e.g., Mixture‑of‑Experts), memory usage, batching, and token efficiency. In a commodity market, firms compete on marginal cost: the lowest‑cost supplier captures volume at a market price set by demand elasticity, while higher‑cost providers risk bankruptcy. Currently, frontier labs (OpenAI, Anthropic) enjoy low marginal costs and high margins due to compute scarcity, but as compute expands, inference volumes may outpace training expenses, allowing lower prices. Chinese labs leverage distillation and state‑backed openness to accelerate model development, posing competitive pressure. Thompson warns that U.S. restrictions on frontier models for cybersecurity could force reliance on Chinese models, urging policy changes to keep domestic defenses competitive.

Comments show a split view on Chinese AI models. Many express anxiety that free, open‑source Chinese offerings could force US frontier labs to lower prices, jeopardizing high valuations and raising security worries about data harvesting and narrative influence. Others counter that open versus closed models matter more than origin, question the extent of China’s advantage, cite comparable technical performance, and argue that distillation is a standard, cost‑effective practice. Several suggestions call for legislative protection of domestic labs and fair‑use data rules, while some emphasize the inevitability of competitive progress and the need for diversified, specialized models.

Human mathematicians are being outcounterexampled

- In May 2026 ChatGPT produced a disproof of Erdős’s unit‑distance conjecture by linking it to the Golod‑Shafarevich theorem; Logical Intelligence auto‑formalized the argument in Lean, and OpenAI’s model Sol later generated a 1.2 M‑line Lean proof covering the necessary global class‑field theory. - In July 2026, during a Lean‑based Fermat workshop, AI tools (Logos, Claude Fable, ChatGPT Pro) were used to draft exposition on finite flat group schemes. An LLM identified a false claim, prompting correction. Subsequently Sol found a counterexample to Grothendieck’s question on whether every finite free group scheme of order n is killed by n; the result was auto‑formalized (≈1 K lines) and merged into mathlib. - The same workflow yielded a formalized counterexample to the Jacobian Conjecture. DeepMind’s Formal Conjectures repository already contained the conjecture’s Lean statement, allowing rapid verification of the AI‑generated proof. - Parallel efforts on modularity‑lifting theorems produced ~250 K lines of Lean code in two weeks, illustrating the accelerating role of large‑scale AI assistance in formal mathematics and counterexample discovery.

Flock Credibility Lost as It Repeatedly Lies to City Councils, Police, & Public

Flock Safety’s automatic license‑plate‑reader (ALPR) system has repeatedly provided inaccurate information to municipal officials and the public. In Oshkosh, Wisconsin (April 2025), a city council member asked whether Flock’s ALPR created heat‑maps of individual vehicle movements; the company’s CISO denied this capability, yet the contract was approved and revoked the next day after Flock admitted the system does generate month‑long heat‑maps of point‑in‑time images. Similar misrepresentations occurred in Loveland, Colorado, where Flock initially claimed no federal access to its data, later acknowledging contracts with U.S. Customs and Border Protection and Homeland Security that allowed direct data sharing. The company also denied ICE access despite evidence that state and local customers shared data with immigration agencies, and it issued a misleading blog asserting ICE had no direct access. In 2025, Flock’s ALPR was used to locate an abortion‑seeking individual across state lines; the company’s “Proactive Search Term Tool” claimed to prevent such misuse, but audits showed simple search‑term circumvention. Flock further fabricated partnerships with the ACLU, both nationally and in New Mexico, which the ACLU has repeatedly refuted. The ACLU recommends that governments avoid contracts with Flock and, if ALPRs are employed, enforce strict data‑retention, sharing, and usage limits.
