Beating AI Express (Dongcha) reports that DeepSeek has adjusted the shutdown schedule for its V4 Pro AI model. Yesterday, the company had announced that once V4.1 Flash launched, all V4 Pro requests would be automatically switched to the new model. The latest update now sets V4 Pro’s shutdown for September 14 at 12:00, with all requests transferred to V4.1 Flash at that time and billed at Flash’s rate. The earlier automatic replacement plan drew opposition from many developers, who worried that their carefully tuned prompts, agents, and production workflows built around V4 Pro would malfunction due to the backend model switch. Some developers suggested DeepSeek retain the old model for a period, allowing users to decide their own migration timing. DeepSeek did not clarify whether the adjustment was related to this feedback. However, compared to the original plan of switching immediately upon launch, the new schedule gives existing V4 Pro users at least several days for migration and testing.

Legendary trader Paul Tudor Jones published a provocative thesis in The Wall Street Journal today, claiming that artificial intelligence (AI) could become the third superpower alongside the U.S. and China. In response to recent warnings from employees at several major U.S. AI companies that rapid AI development threatens human society, Jones argues this threat is real and requires coordinated action from the world’s major powers. He stresses that the U.S. and China must commit to setting timelines to control AI development and proliferation in a safe, controllable, and understandable manner. “If an AI model repeatedly rewrites itself thousands of times, what is the chance it will make a single error, leading it to pursue a goal inconsistent with its intended target, thereby causing harm or even catastrophic consequences to humans? Now multiply that risk by tens of thousands of users,” Jones wrote. He notes that a new superpower—AI—is about to enter the global arena. It is unpredictable, endless, and could far outpace the scale of existing powers, whether individually or collectively. He calls on leaders of existing major powers to make AI safety their top priority for the remainder of their terms in office.

Beating AI Express News: Ant International, Visa, and Mastercard announced a partnership to advance mutual recognition of KYA (Know Your Agent). KYA can be understood as "identity authentication for AI Agents" — it confirms who an agent is and who it represents, allowing payment networks to assess its trustworthiness. The three companies aim to integrate this authentication system. Going forward, once an AI Agent completes verification in one ecosystem, it will be recognized across other payment networks with its identity and trust data already on file, eliminating the need to re-register and re-verify from scratch each time.
