Tencent pledged to publish Hy4's weights, the trained parameters that let anyone download and run a model, which would let anyone modify a model that works software on its own. The company says a system card will accompany the release and that the release will focus on risks such as cybersecurity and biosecurity. Its own tests put the hallucination rate, the share of answers stating false information, at 7.2%, down from 12.95% for the preview version. [Sina Tech](https://finance.sina.com.cn/tech/shenji/2026-11-04/doc-inixpvuw9459767.shtml) [state-affiliated] - **Taiwan lawmakers weigh adding chips and wafer materials to export controls on mainland** — Taiwan's legislature held a hearing Monday on a Foreign Trade Act amendment that would extend export controls on mainland China from chipmaking equipment to specific chips, key wafer materials and components. Mainland chipmakers and electronics makers that buy chips, wafer materials or parts from Taiwan would see those purchases come under control too. Exports of 12 categories of wafer fabrication equipment, including machines that polish wafers flat between processing steps, already need a government permit as strategic high-tech commodities. The draft would also raise criminal penalties for illegal exports to the mainland and for transshipment, routing goods through a third place before they reach their real destination.

Driverless cars most need testing in rare, dangerous situations that ordinary driving seldom produces. Simulated road users that react to the car let Baidu rehearse those situations in volume off the street. Every simulated car and pedestrian is an AI agent that makes its own decisions, said world-model team head Yang Ze. The system also generates live camera and lidar (laser-ranging sensor) data, so whole trips can be tested with the car's actions changing what happens next. [InfoQ China](https://www.infoq.cn/article/tIt75FRqU2hwy4eWrOIu) - **Xiaomi humanoid robot works its first full eight-hour shift in its car factory** — Xiaomi's CyberOne 02 humanoid robot completed its first full eight-hour continuous shift at a station in the company's car plant, lining up large center-console side panels for final assembly. Eight hours is a full factory shift, the span a robot must run at line pace to cover a station's daily output by itself. Xiaomi says the robot corrected anomalies on its own and posted success rates of 94% to 98% across the stations it now works. The panels are large, irregular and arrive in random positions, which 36Kr reports demands more precise visual positioning and grip control than standard parts. The factory trial began in March with three autonomous hours at a nut-loading station.

AI coding assistants send the code and documents they work on to their makers' servers, so the block keeps that material in-house. The rules, which TMTPost reported from a social media leak, also cover employees' self-paid accounts. Technology Vice President Hong Dingkun wrote internally that a leak of higher-tier content would be very serious and that forcing staff onto in-house tools works poorly. In July, a vulnerability platform under China's industry ministry warned that Anthropic's Claude Code sent users' location and identity data to remote servers without consent.

Open-weight models can be downloaded, run and modified by anyone, so the download count is a rough gauge of how far Alibaba's models have spread into other developers' systems. DeepSeek research engineer Gao Xi said at the same summit that opening new model architectures and training methods brings artificial general intelligence sooner than guarding a short-lived lead. Liu said the team opens small and mid-size models so researchers who lack computing power can experiment at lower cost.

In it, robot AI models write their own training code, train in simulation or the real world and are scored on test results. Coding and experiments, work engineers normally do, would pass to the models, leaving people to set goals and judge results. Trained robot models can approach 100% success on some single, fixed factory steps, he said, but leading multimodal models' success stays low on precise tasks such as assembling and taking apart a phone or threading a needle.

A laser shot costs little compared with an interceptor missile, which makes lasers a candidate defense against cheap drones arriving in large numbers. The system comes from an institute of the Aviation Industry Corporation of China (AVIC), the state aviation conglomerate. Lab director Zhou Shuiliang says performance hinges on the system's rare-earth-doped optical fiber, which carries and amplifies the laser energy. Hand tuning of the dozens of settings used to draw the fiber had made production slow and fiber quality inconsistent, and team member Tan Guang proposed replacing it with an algorithm.

Storage that discharges for eight hours or more can carry daytime solar output across a full evening, far longer than the 2.5-hour global average duration that research firm Wood Mackenzie reports. EnerQB was designed for a 24 gigawatt-hour portfolio of Australian projects, enough to deliver 3 gigawatts for eight hours. The first units, each holding 5.64 megawatt-hours, will be deployed at the Stanwell power station in central Queensland. [EV Industry Supply Chain](https://www.evchanye.com/2026/1104/56019.shtml)
