GLM-5.3's weights, its trained parameters, are public, so anyone can modify them. Anthropic says the model was released without meaningful safeguards and calls for governments to safety test sufficiently capable models, including GLM-5.3's successors. Chinese AI outlet QbitAI says Claude's resistance to the same attacks comes largely from product design and closed weights. Unmodified GLM-5.3 refuses harmful requests about as often as Claude on three public benchmarks in Anthropic's report, QbitAI notes. Zhipu delayed releasing GLM-5.3's weights after its August launch to finish safety evaluation, QbitAI reports.

Huawei executive Richard Yu said advanced chipmaking capacity remains limited and the phone chips share one pool with Ascend, Huawei's AI chips, so phones and AI chips compete for the same output. Logic folding, which Yu said uses more wafers, stacks layers of circuitry and links them vertically, Huawei's route to more performance without moving to a smaller manufacturing process. Huawei rates the top-end Mate 90 Pro Max, which runs the Kirin 9050 Pro, 31% faster overall than the Mate 80 Pro Max, and the entry Mate 90, on the Kirin 9030, 27% faster than the Mate 80.

The mission shows how the solar wind, the stream of charged particles flowing from the sun, interacts with Earth's magnetic field. That interaction drives magnetic storms, which can disrupt satellites, navigation and power grids. Sina Tech's report says SMILE's soft X-ray imager makes it the first spacecraft to observe Earth's magnetic field in X-rays in detail and over long periods. Its ultraviolet camera can photograph the aurora for up to 44 hours without a break, which the report calls the longest continuous run of any spaceborne aurora imager.

A variable-speed unit can vary how much power it draws while pumping water uphill for storage, so the plant can soak up fluctuating wind and solar output. Changing its rotation speed by 7% lets the unit adjust its power in real time across a 50% range, according to a Xinhua report carried by Global Times. The unit has been on China's energy sector list of first-of-its-kind major equipment since 2022. The plant is due to run fully in the first half of 2027.

The plant adds capacity for flip-chip ball grid array (FCBGA) substrates, the layered base a large data center processor mounts on to carry its signals and power to the circuit board. Guangxin, in Huangpu since 2021, already makes substrates for radio-frequency chips and FCBGA. Public records show it is a core supplier to several leading global packaging firms. The district hosts more than 150 chip companies, and its semiconductor output topped 31 billion yuan ($4.6 billion) from January through August.

PLA Daily, the Chinese military's official newspaper, says domestic ultra-high-purity aluminum helps secure raw materials for semiconductors and other strategic industries and reduces dependence on outside suppliers. Zone refining sweeps impurities to one end of a metal bar by moving a narrow molten band slowly along it, and at this purity impurities make up less than two parts per million.

A University of Manchester team won in 2025 on Zhishen's earlier Gangbeng L1, meaning that the challenge's last two winners, from Singapore and Britain, both competed on Chinese-built hardware. Zhishen also sells the robots for power-grid inspection, firefighting, emergency response and security work. Its newest model, the Gangbeng L2, has joint motors with a peak torque about double the previous generation's, the company says.

The patrol follows the drone and warship drills there that CTD reported in the [Sept. 28](https://chinatechdaily.org/archive/china-daily/2026-09-28/) edition. The command says its forces have kept strengthening patrols there since September to tighten control of the area, a feature the Philippines also claims. In July, the Philippines deposited a chart of the shoal's baselines and territorial sea with the United Nations, the same week it presented a separate UN bid to extend its seabed claim off western Palawan.

The account adds detail to the dialogue launch CTD reported [Sept. 28](https://chinatechdaily.org/archive/china-daily/2026-09-28/), naming an AI incident communication channel and measures to prevent AI misuse as the most ready areas for cooperation, where experts on both sides already broadly agree. Xiao Qian, a deputy director at Tsinghua University's Center for International Security and Strategy and core participant in unofficial China-U.S. talks, confirmed to the author that both items align with China's interests.
