Amodei's pacing plan puts outside auditors inside Anthropic

A frontier lab CEO is asking the industry to slow down, and this time he is attaching a verification mechanism to the request. Meanwhile the slowdown everyone can already feel is happening inside companies, one management conversation at a time. Anthropic CEO Dario Amodei published "We Must Pace the Frontier," an essay arguing that capability gains are outrunning the work needed to control them, and that the fix is deliberate, verifiable deceleration rather than a halt.

Motus2: a robot world model that grades its own actions

Shengshu Technology, the Chinese world-model lab, shipped the rare robotics release where the loop actually closed: one model that acts, imagines, and scores itself — then learns from the grade. Shengshu released Motus2, a "self-evolving" general world model for dexterous manipulation that puts three capabilities — acting, predicting, and evaluating — inside one shared-parameter video-action model, according to the project page and the paper on arXiv.

Google's TimesFM-3 forecasts every variable at once

A quiet-but-real model release out of Google Research, and a state-backed number for just how much computation the agent era is expected to eat. Google's TimesFM-3 became the first model in the family that can forecast many variables at once — and it fills the entire future in a single pass. The 330-million-parameter transformer chops each series into patches of 32 points, normalizes them onto one scale, then alternates two attention directions: along time within a series (past values only, so…

Ex-Li Auto execs raise nine figures for a robot foundation model

Robot brains and AI infrastructure drew the money this hour: a Chinese embodied-model lab run by two of Li Auto's most senior AI executives closed a nine-figure angel round, and one of OpenAI's most visible former leaders resurfaced on the board of a data-center company heading for an IPO. Xieyue Intelligence has raised several hundred million yuan in an angel-plus round, announced September 12, with Linear Capital, Junshan Capital, Hongyi Capital and Yinshan Capital participating.

OpenAI drops Caltech math hackathon after mathematicians cry 'slop'

The friction between AI and its neighbors is getting legal teeth this midday: a lab retreats from academia's loudest critics, an infrastructure startup hires a lab's alumni for its IPO run, and a Chinese court puts a prison term on jailbreaking a model. OpenAI has withdrawn its sponsorship of the Caltech Mathathon, the student-run hackathon for research-level mathematics, after an open letter from mathematicians accused AI companies of advancing a campaign of "slop mathematics." The event …

Fields Medalist founds institute to prove AI safe — like cryptography

Two kinds of trust shipped today: a Fields Medalist building the mathematics of "safe", and two Chinese platforms engineering agents that can explore without breaking things. **Jacob Tsimerman, who won math's Fields Medal in July, is founding an institute whose whole premise is that AI safety has no shortcut yet — and he wants to build one.** The Mathematical AI Safety Institute (MAISI), reported by The New York Times, will start research in January 2027 in the San Francisco Bay Area with 10…

Garry Tan tells AI's accusers to relax — 'I would do nothing' about distillation

Y Combinator CEO Garry Tan says he would "do nothing" about Chinese labs distilling American frontier models — a direct counter to the loudest story in AI right now. Speaking with CNBC at YC's Demo Day, Tan argued the right goal for a regulator isn't blocking distillation but striking a balance where open-weight models keep giving people "freedom and access" while frontier models keep a price premium that funds their research.
