first_img Zhipu Tangjie filed a defamation complaint against Xiaohongshu, ZCode has been open-sourced for rectification

On September 21, netizen "Zhang Kangkang kk" revealed on social media that Tang Jie, the founder of Zhipu and a professor at Tsinghua University, filed a complaint on Xiaohongshu regarding a user post. The complaint stated that the post used phrases like "code is pretty much the same as copy, both start with c and steal code" without factual basis, fabricating rumors that Zhipu's ZCode was involved in code theft and plagiarism. It also used terms like "Uncle Tang Jie" to associate Tang Jie with the plagiarism rumors for character defamation, while utilizing AI technology to synthesize Tang Jie's image with anime materials in a defamatory context. The complainant believed the content constituted malicious defamation and commercial disparagement, damaging both Tang Jie's personal reputation and Zhipu AI's reputation, and requested the platform to take down the post and deal with the user who posted it.On the same day, Zhipu announced that it had completed rectifications regarding the safety issues of the independent desktop AI programming client ZCode in response to community feedback and apologized to all users. The company has open-sourced ZCode, handing over the code to community supervision, and will establish a regular product security vulnerability mechanism moving forward. Previously, developers discovered that ZCode had silently uploaded user local repository data without prior notice. On September 18, Zhipu publicly apologized and made an emergency fix, explaining that the root cause was the "repository indexing" feature, which was enabled by default and had no option to turn it off. On September 20, Taiyuan Chengming Technology Co., Ltd. sent a letter to Zhipu, accusing ZCode of unauthorized uploading of company data assets and trade secrets, making claims for rights protection and reserving the right to pursue legal responsibility.

first_img TSMC N2 mass production, Zhongsha Shengyang Semiconductor and other supply chains benefit

TSMC's 2-nanometer N2 mass production marks the transition of advanced semiconductor processes from FinFET to GAA generation. Industry analysts point out that with the simultaneous increase in process complexity, CMP track counts, wafer monitoring frequency, and material specifications, the demand for equipment, CMP consumables, reclaimed wafers, and advanced materials is rising, providing growth opportunities for suppliers like Zhongsha, Shengyang Semiconductor, Xinying Materials, and Songsheng. TSMC's N2 adopts nanosheet GAA technology, which can improve performance by 10% to 15% at the same power consumption compared to N3E, or reduce power consumption by 25% to 30% at the same speed, with chip density increasing by over 15%.In Zhongsha's largest customer Diamond Disk business, advanced processes account for 63%, with N3 and N2 each accounting for 22%, and 1.4 nanometers already shipped in small quantities; after N3 enters N2, the value of CMP content increases by 10% to 15%. Shengyang Semiconductor's monthly production capacity for reclaimed wafers is adjusted to 1.1 to 1.2 million pieces by the end of 2026, with a capital expenditure budget of 4.82 billion yuan for 2026, and it is estimated that the compound annual growth rate for reclaimed wafer expansion from 2025 to 2029 will reach 25% to 30%. Xinying Materials' core products Rinse, BARC, and EBR are expected to see shipments rise seasonally as N2 capacity ramps up, while Songsheng's semiconductor revenue accounted for 66% in the first half of the year, with a year-on-year increase of about 25%, and TSMC-related revenue increased by about 170% year-on-year.
