On October 20th, CITIC Construction Investment released a report highlighting that on October 17th, DeepSeek rolled out an updated V4.1 Flash version. This upgrade saw its DeepSWE metric soar from 74.2% to 77.0%, all while keeping API pricing steady and introducing open search and web scraping interfaces. According to third-party assessments, the new version successfully completed all hidden tests under the high-difficulty setting of the Pi framework, with an average cost of just $0.045 per task—a significant 77.7% reduction compared to the medium setting of GPT-5.6 Sol. Additionally, Zhipu unveiled a specialized legal model, and Jieyue shared details of its long-term Agent training initiative. These advancements in domestic models—covering enhanced capabilities, reduced deployment costs, and improved tool support—are anticipated to fuel growth in enterprise workflow applications and drive up demand for inference services. Against this backdrop, we recommend focusing on enterprise-level AI applications, computing power services, as well as domestic chips and supernode technologies.
