Chinese chipmaker CXMT reported DRAM trial chip validation for its sixth-generation process, whose 4F² layout gives each memory cell about two-thirds the silicon of today's standard design. Meituan says it trained LongCat-2.5 on Chinese chips, and Leiphone reports the food delivery company's 1.6-trillion-parameter model is the largest training run completed on Chinese hardware to date. Apple and Alibaba set December China launch for Apple Intelligence features that can send iPhone users' requests in Siri and Apple's writing and camera tools to Alibaba's Qwen model. AI firm ModelBest's agent outperformed DeepSeek's chip code with a kernel that ran 9.8% faster on Nvidia's B200, QbitAI reports, and Huawei's Ascend software team said the open-source agent topped three of its kernel performance leaderboards.
ChangXin Memory Technologies (CXMT), a Chinese maker of DRAM, the working memory in computers, said trial chips from its sixth-generation process, which it now says is built on the 4F² cell design it reported progress on in the October 13th edition, have passed validation. Each memory cell in the process's 4F² layout takes about two-thirds the silicon of today's standard design, so a working process would put more memory on every wafer. Sina Tech judges CXMT the first company to report reaching this stage with 4F², a layout Samsung and SK hynix are also developing. CXMT's research spending rose 73% year on year to 11.07 billion yuan ($1.7 billion) in the first three quarters, PingWest reports.
