Jensen Huang Announces Formation of Open Security AI Alliance to Enhance Cyber Defense with Open Source Models
On July 27, Jensen Huang, founder and CEO of NVIDIA, posted again on the X platform, stating that attackers have mastered cutting-edge AI, and that defenders need a 'cutting-edge AI ecosystem' composed of both open-source and closed-source advanced models, amplified by the global community to enhance defense capabilities. He mentioned that during the recent Hugging Face security incident, some closed-source AI hindered critical forensics, while open-weight advanced models played a role in mitigating intrusions. Therefore, he decided to promote the establishment of the Open Security AI Alliance. Previously, NVIDIA (NVDA.O) collaborated with Palantir, IBM, CrowdStrike, SpaceX, and Hugging Face to form the 'Open Security AI Alliance' aimed at strengthening the security of open-source AI. -

Russia Develops 150nm Lithography Machine, Performance Comparable to Pentium 4 from 20 Years Ago
On July 22, according to Fast Technology, Russia's Green City Nanotechnology Center (ZNTC) has successfully developed a prototype of an electron beam lithography machine (ELL) with a design standard of 150nm. The project is a key research and development task under the framework of Russia's national plan for scientific and technological development, codenamed Progress ELL 150. This device is mainly used for manufacturing photomasks, and can also directly draw circuit patterns on substrates without using masks. The 150nm process roughly corresponds to the performance level of Intel's Pentium 4 from 20 years ago. In 2025, ZNTC demonstrated a similar device with 350nm resolution, and has now advanced to 90nm and 130nm technology nodes. Industry experts point out that such equipment is only suitable for small batch production of specialized chips in fields such as aerospace and defense.
