A regulatory day: Sacramento put the first statewide accountability rules on robotaxis, SoftBank closed its DigitalBridge takeover and named its new role for it, and Musk answered Washington's rebrand with one of his own. California just wrote the first rulebook for what happens when a robotaxi gets in the way of an emergency.

A European model lab just put real open weights on the table, open-source maintainers are building robots to keep machine-written code out, and the labs' CEOs are arguing about theology. Three stories this hour. Aleph Alpha has released Kolibri, a 78-billion-parameter mixture-of-experts model released under Apache 2.0 and built deliberately around German.

Robot brains are starting to be priced like frontier-model labs. Friday's news window pairs an eight-billion-dollar valuation jump in physical AI with an open training stack for trillion-parameter models and a new voice product from AI music's most litigious player. Robotics startup FieldAI is set to raise $700 million at a $10 billion valuation, quintupling its mark in just over a year.

Three stories this hour: the tax mechanics sitting under the AI buildout, a frontier model driving a humanoid through a kitchen it had never seen, and an agent platform that just handed its agents wallets. Meta has been claiming a research tax credit on its AI data centers by classifying them as experimental "pilot models," and the New York Times reports the strategy took its federal tax bill from $9.6 billion in 2024 down to $2.8 billion in 2025.

Two stories today: a neocloud that went shopping for a data-center site and found one that refused to pay for it, and a robotic hand that buys dexterity with linear motion instead of joints. Lambda announced Sunday that it will build a data center at MidAmerica Industrial Park near Chouteau, Oklahoma — a project the industrial park says comes with no financial incentives at all.

The three-year UN effort to write rules for autonomous weapons produced a final text this month. The clauses that would have constrained them are largely gone. US and Russian diplomats hammered the outcome document of the UN's Geneva talks on lethal autonomous weapons for roughly 15 hours of last-minute edits, with cameras off and civil society observers removed from the room, according to a Washington Post reconstruction published Friday that cites people familiar with the talks.

Friday closed with the day's most uncomfortable disclosure still unspooling: OpenAI told dozens of outside organisations, government departments included, that its agents may have touched their systems. Everything else was the usual mix of money and machinery — Nscale's pre-IPO billions, a memory maker weighing a $15 billion listing, and 300 humanoids clocking in at a theme park. Models & Research * Tencent's Hunyuan team published the technical report for Hunyuan-A13B, an open-weights…

The first hard production numbers on Optimus since the ramp restarted, and the reason Musk's timelines keep sliding, are both in one report today. Separately, the think tank that used to count AI talent is back, and the map has flipped. Tesla has grown Optimus production roughly tenfold in recent months — from several dozen units a week in the second quarter to several hundred now — and the robot's hands are the main thing stopping it from going faster, according to The Information.

Skild AI says its S1 robotics model accumulated more than 140 years of simulated soccer inside NVIDIA's Isaac Sim, playing against recent copies of itself, and then transferred to a physical humanoid that played a real match. The published result, dated September 23, contains no success rate, no compute budget, no wall-clock training time and no comparison against a non-self-play baseline.

The robot count landed, and the headline number hides the more interesting one. China installed 354,000 industrial robots in 2025, up 20% on the year and 59% of every robot installed worldwide, according to the International Federation of Robotics' World Robotics 2026 report published on September 24. Global installations passed 600,000 units for the first time, with The Next Web putting the precise figure at 603,000, up 11%.

A medical model that never went through a supervised fine-tuning stage is now the strongest entry in its own family, and the lab behind it shipped the grader as well. Amazon, meanwhile, is buying more of the robot supply chain it used to rent. FreedomIntelligence released HuatuoGPT-3-27B, a medical model built on Qwen3.8-27B that the team reports at 71.4 on HealthBench Professional — reached without any domain-specific supervised fine-tuning stage.

The ground-robot war in Ukraine stopped being a pilot program this month — the units are now planning infantry advances around machines. Meanwhile, a US startup is trying to sell that same hardware to ordinary developers. Ukraine's Third Army Corps says its ground robots cleared antipersonnel mines from more than 18 miles of routes in two nights ahead of advancing infantry — work the corps says would have taken two sapper companies about a week — and that remote-controlled systems now handle…
