--- date: 2026-10-27 subject: "Baidu open-sources document AI for any length | AVIC unit tests giant metal press | 360's AI bug hunter passes state test" --- **Baidu open-sourced a long-document OCR model** that it says can parse files of any page count, and its technical report says the model cut memory use on a test document from 47GB to 1.77GB. **An AVIC subsidiary pressure-tested a hot isostatic press** that Sichuan Aviation Industry Chuanxi Machinery says has the world's largest hot zone and reached 205 MPa in testing. **360 Group's AI bug hunter passed a state evaluation** and is the first product in China to meet all 12 requirements of a new assessment by a research institute under the industry ministry. **Xiaomi unveiled a robot hand for its car plant** and says simulated grasps drawn from factory procedures showed that 21 degrees of freedom gave the largest gains in stable gripping. # Top Stories - **Baidu open-sources document-reading AI it says parses files of any length** — Baidu open-sourced Unlimited OCR 2, an optical character recognition (OCR) model that turns scanned pages into text. The company calls it the world's first system to parse documents of any page count. Models reading long files normally keep a memory record of every page already seen, which caps how long a document one chip can handle. Baidu's technical report says the new model cut that memory from 47GB to 1.77GB on 100-plus-page documents, so book-length files need far less chip memory. On two long-document benchmarks, one Baidu-built, Baidu says the model beat Alibaba's Qwen 3.8-Max and Google's Gemini-3.8-Flash. Tech outlet QbitAI fed it an 884-page edition of "The Lord of the Rings," and spot-checked output pages matched the original. [PingWest](https://www.pingwest.com/w/318803) [QbitAI](https://www.qbitai.com/2026/10/505773.html) - **Aircraft maker AVIC's subsidiary pressure-tests what it calls the world's largest hot isostatic press** — Sichuan Aviation Industry Chuanxi Machinery, a subsidiary of state aircraft conglomerate AVIC, says its hot isostatic press, the world's largest by hot-zone size, has passed its pressure test. Such presses use heat and high-pressure gas to squeeze internal voids out of metal parts. The hot zone, the heated chamber, caps how large a casting they can treat in one piece. This one measures 2,400 mm (about 7.9 feet) across and 3,500 mm (about 11.5 feet) tall. Presses of this kind densify large titanium and superalloy castings and 3D-printed parts. Sichuan province's special equipment inspection institute monitored the test in Anshun, Guizhou province, where the unit reached 205 MPa, roughly 2,000 times atmospheric pressure.

Such tools can audit code at a scale human teams cannot, and CAICT's first published results give Chinese buyers an official yardstick for judging them. Tulongfeng met all 12 of CAICT's requirements, which cover the range of software examined, task complexity, automation and accuracy. 360 says the system has found more than 15,000 vulnerabilities, including long-hidden Windows and Office flaws that Microsoft credited. More than 500 companies, including operating system makers Kylin Software and UnionTech, use it for security testing. [PingWest](https://www.pingwest.com/w/318814) - **Xiaomi unveils robot hand designed around tasks in its own car factory** — Xiaomi disclosed a robot hand with 21 degrees of freedom, the independent ways a hand can move, designed for flexible manufacturing in its electric-car plant. More joints let a hand grip more kinds of parts but add motors, cost and points of failure. Xiaomi used factory data to find where adding them stops paying off. In simulated grasps drawn from the plant's work procedures, hands with 17 to 21 degrees of freedom gripped stably up to 38% more often than hands with 6 to 15. Xiaomi found 21 gave the largest gains, with returns slowing markedly at 23 or more. It says the hand built to that figure outgripped its simpler predecessor in grasping tests.

DPU performance has been hard to compare across vendors' incompatible designs, and the standard gives buyers one basis for selecting and testing these chips. It sets requirements for developing DPUs and for deploying, running and managing them in AI computing clusters. The China Academy of Information and Communications Technology, a research institute under the industry ministry, led the drafting, with China Telecom, ZTE and DPU maker Yusur Technology among the co-drafters.

The drill revives the Sharp Knife series after a 14-year break, and its program includes manned-unmanned coordination, troops operating alongside drones. Military commentator Song Zhongping told Global Times the featured scenario is a mountain-jungle hostage rescue, from drone reconnaissance through helicopter rope insertion to close-quarters room clearance. The two earlier rounds ran in Bandung, Indonesia, in 2011 and in Jinan, Shandong province, in 2012. [Global Times](https://mil.huanqiu.com/article/4Tm5XtNzIrc) [China Military Online](http://eng.chinamil.com.cn/2025xb/C_251453/EC/16496359.html) [state media] # Talent & Capital - **TikTok owner ByteDance advertises chip architecture and AI compiler jobs** — ByteDance is advertising chip architecture, compiler and quantization jobs, including work on compute-in-memory designs that calculate where data is stored, according to Yicai's search of its listings. Compilers and quantization tools decide how efficiently an AI model runs on a given chip. iFlytek executives quoted in the same report say such tuning is how they offset domestic chips' lag behind Nvidia GPUs in memory capacity and bandwidth. Liu Quan, chief technology officer of iFlytek's Ciyuan Spark unit, said a model version that once took about a month to train could take about three without such optimization.
