Changan ships a self-developed end-to-end driving LLM after 1.45 billion km of validation

Changan became the latest major Chinese automaker to put a self-developed end-to-end driving model on the road, releasing what it calls an in-house large model for assisted driving that has been validated on roughly 1.45 billion kilometers of driving data, according to Chinese financial outlets. The release puts one of China's "big four" state-owned automakers into the same architectural camp as XPeng, Huawei, Li Auto and the other Chinese OEMs that have decided the road to L3 and beyond runs th

Saudi Arabia's HUMAIN ships its first Arabic LLM — on top of China's MiniMax

Saudi Arabia's state-backed AI company HUMAIN released the first large language model purpose-built for Arabic, and the foundation underneath isn't Saudi at all: it's MiniMax's open-weights M3 stack. The Riyadh-based unit of the Public Investment Fund disclosed the model on its developer platform Humain Node, framing it as the backbone of a national AI platform under the kingdom's Vision 2030 diversification push. The pivot matters because HUMAIN was previously promoting ALLAM 34B as its flagshi

Astribot's SmoothRL gives robots online learning that survives a thrown ball

Online reinforcement learning for real robots usually assumes the world will politely pause. Astribot's new framework shows it doesn't have to — and the gains come from correcting the actions that already started, not the ones the model just planned. Stardust Intelligence (Astribot) released SmoothRL, an asynchronous online reinforcement learning framework built for high-dynamic manipulation. The lead author is Astribot's Wang Jianan, with Gao Guang and Nong Yuxuan as co-first authors; the rese

Deep Dive — Brockman breaks his silence: the Stratechery interview and what OpenAI is actually saying

Ben Thompson published a 10,000-word interview with OpenAI president Greg Brockman on Friday morning, recorded before the Astra launch and covering everything from Brockman's acting career in North Dakota to the company's place on the AI value chain. It is, by a comfortable margin, the most substantive public document OpenAI has produced about how it thinks about itself in months — and we already had a week full of OpenAI coverage. The interview lands the day after OpenAI ships GPT-6 Astra and s

GPT-6 Astra scores 61 on Artificial Analysis, five behind Anthropic

Thursday's launch rhetoric met its first independent scoreboard, and the scoreboard is more interested in price tags. Also: Tesla quietly opened a door for businesses that want to buy and run Cybercabs themselves. Artificial Analysis put GPT-6 Astra at 61 points on its Intelligence Index — five behind Anthropic's Claude Fable 5.1, which tops the table at 66 — in the first full third-party evaluation of OpenAI's new flagship, published the same day as the launch. The gap shrinks on agentic codin

Today in AI — September 3, 2026

The evening half of the day ran on two tracks: capability and consequence. OpenAI shipped GPT-6 Astra and said out loud what it has been circling for a year, Moonshot quietly filed for a Hong Kong listing, and while Washington argued about who gets to write the rules, New York City simply switched AI off for 600,000 schoolchildren. Models & Research * OpenAI launched GPT-6 Astra, the model it says crosses into the "AGI era," with Greg Brockman declaring "we are now in the AGI era" on launch

Accel is in talks to lead a $1B round for Thinking Machines at $40B

The AGI-era headlines have quieted down, so the money is doing the talking instead. Tonight: Mira Murati's lab tests whether pedigree still clears a $40 billion price, Microsoft undercuts the transcription market, and Zed turns a sixty-year-old hypertext vision into an agent feature. Accel is reportedly in talks to lead a $1 billion round valuing Mira Murati's Thinking Machines Lab at $40 billion — a step down from the $50 billion the company was said to be seeking late last year.

OpenAI's Astra cuts the bounded prime gap record to 186

Two things worth your attention this evening: OpenAI quietly posted a paper it says was proved by GPT-6 Astra, and New York City decided that 600,000 children should not touch generative AI at all. One is a claim about machine reasoning at the frontier of number theory. The other is a claim about what children need before they ever meet it. OpenAI has published a paper, "Improved Short Gaps Between Primes," whose abstract states plainly that the proof is due to GPT-6 Astra — and it improves the

OpenAI ships GPT-6 Astra and says the AGI era has started

OpenAI's newest model is out the door — with a claim from its president that this is the one history will name. Alongside it: Meta is buying your usage data outright, and Anthropic is siding with regulators against its own industry. OpenAI released GPT-6 Astra on Thursday, and president Greg Brockman used the launch briefing to say the company has crossed into AGI. "If we fast-forward a couple of years, and we look back and say, 'When was it, really, that AGI was created?' I think it's going to

Ant open-sources a finance model built for research, not chatter

Two open-weight releases landed within hours of each other today, and both are about the same unglamorous problem: making a model do a real job end to end instead of answering plausibly. Ant Group put the weights for its finance-tuned Ling model on Hugging Face, and the local-inference crowd got a speedup that doubles throughput on a consumer card. Ant Group released the open weights for Ling-3.0-flash-Fin, a finance-tuned model that trades breadth for verifiable work. The model keeps the Ling-

Google's WeatherNext 3 trades the six-hour lag for hourly forecasts

Two stories this afternoon point the same direction: AI is being pushed closer to the physical world it's supposed to describe. Google rebuilt its weather model to learn from live satellite and station readings instead of yesterday's simulation output, and Equinix is turning its colocation floors into a marketplace for inference — the part of AI that has to sit near the people using it. Google released WeatherNext 3, and the important change isn't the resolution — it's what the model learns fro

How to — tell a real benchmark from a marketing one

Every model launch ships a benchmark table. Almost every one of them is, in some sense, true. None of them are telling you the same thing. The job is not to find a fake benchmark — most aren't fake — but to find the one whose number you can carry into a decision. Here is the routine. Benchmarks are the scoreboard the field runs on, and the scoreboard is under strain. Terminal-Bench 4.0 spent recent releases removing saturated tasks and fixing broken ones; SWE-bench had to be split into a "Verif
