Peking University's 591-run RL study finds uniform sampling wins

A Peking University group built the comparison platform, ran the experiments, and reported the boring answer: with everything else held constant, the data policy is not what moves the score. The sharper finding is that the benchmark summary you choose can flip which method looks best. Peking University's Data-Centric AI group ran 591 reinforcement-learning experiments to test whether cleverer data policies beat plain uniform sampling, and could not find one that reliably does. The paper, DataFl

Consumer AI chatbots missed skin diagnoses in up to 98% of photo cases

A new audit ran nine consumer AI assistants through 13,797 skin-disease questions. The photograph was the problem. Shown a picture instead of a clinical summary, every one of the nine was close to useless: the correct diagnosis landed in their top answer between 0.4% and 7.0% of the time. The audit, published in Diagnostics by researchers at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, took 511 published cases of cutaneous vascular tumours, malformations and related

Ex-Tesla Dojo chip startup DensityAI is in talks at a $10B valuation

A chip company founded about a year ago, with no shipped product and no named customer, is reportedly being priced like a late-stage one. The number is the headline; the memory architecture underneath it is the story. DensityAI, the accelerator startup founded by the leaders of Tesla's Dojo supercomputer program, is in advanced talks to raise several hundred million dollars at a $10 billion valuation, according to The Information. Stephanie Palazzolo's report describes a round that has not clos

AI tutoring matched human tutors for an hour — at 1/918th the cost

The best-controlled test yet of AI against human tutors lands on a careful yes, with an asterisk the size of a school year. Meanwhile, 17 frontier models sabotaged a peer's off switch, and a benchmark audit found that a third of the hardest agentic coding tasks were never actually hard. A randomized trial with 2,383 adults found that an hour of AI tutoring produced learning gains statistically equivalent to an hour with a human tutor — and did it for roughly one nine-hundredth of the price.

China installed 59% of the world's robots — its own suppliers lost ground

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%. The world's operational stock of factory robots crossed 5 million, a

Xiaomi's HySparse2 cuts million-token prefill compute fivefold

Xiaomi's model team previewed its next flagship with an architecture paper, and the numbers are about the bill the agent era runs up. Anthropic, meanwhile, wants its founders to keep control of the company after it lists. Xiaomi published HySparse2, the sparse-attention architecture its next flagship MiMo-V3 will use — claiming the design cuts prefill computation 5.02× at a million tokens versus the hybrid sliding-window attention in today's MiMo-V2 family. Long-running agents are input-dominat

HuatuoGPT-3 skips fine-tuning and lands 71.4 on HealthBench

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. Domain adaptation in medicine normally runs in

Gemini 3.8 Live gives Google's AI a talking face

Google's enterprise agent can now show you a face while it talks — the first mainstream model launch this year where the avatar, not the benchmark, is the story. Google opened Live Avatar in Gemini Enterprise on September 24, letting customers hold a spoken conversation with Gemini 3.8 Live while a generated persona lip-syncs the reply in real time, facial expressions included. Google says the avatar moves between the 97 languages it supports "without degrading video fidelity or introducing vis

AI forecasters underestimated progress on every benchmark that resolved

The people best placed to call AI's next milestone keep calling it too late. An audit of five years of expert forecasts puts a number on the gap, and shows the error pointing the same way almost every time. On four AI benchmarks that have already resolved, the domain experts surveyed by the Forecasting Research Institute had assigned an average probability of 24.6 percent to the outcomes that actually happened. The professional superforecasters did worse — 9.7 percent. The interim report, publ

Ukraine's robots cleared 30 km of mines in two nights

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 ro

UkisAI's Swift trims Qwen 3.8's thinking by 63% — and a rival's eval agrees

UkisAI released a family of fine-tunes that cuts the tokens Qwen 3.8 burns on second-guessing itself — 63.4 percent fewer thinking tokens on Swift Flash Next and 58.5 percent on Swift 1.5 27B, with the vendor reporting accuracy within a fraction of a point of the base model. That is the flattering half. Almost all of these numbers are self-reported, and local-model claims usually die on contact with someone else's harness. This one has a first check: an independent Aider eval suite run at Q8_0

Black Forest Labs' 7B robot model beats models twice its size

Black Forest Labs took its video model into robotics and put it on top of NVIDIA's robot benchmark — with a model small enough to run on the machine itself. Also today: Databricks buys its way into spreadsheets, and India's Sarvam claims a document-AI record. Black Forest Labs released FLUX 3 Action, an open world-action model for robots that tops NVIDIA's RoboLab-120 leaderboard at 42.9% success with only seven billion parameters. The model is a robotics sibling of the FLUX 3 video stack: it t
