III. AI Industry & Corporate Developments

1. Revised Regulations on the Protection of Integrated Circuit Layout Designs promulgated

As of August 4, the revised *Regulations on the Protection of Integrated Circuit Layout Designs* were promulgated, effective October 15, 2026. The Regulations aim to protect the exclusive rights to integrated circuit layout designs, encourage innovation in integrated circuit technology, and promote the development of science and technology.

2. Independent Variable Robotics open‑sources HOST framework: robots can "learn in seconds" new skills by watching human videos

On August 3, Independent Variable Robotics released and open‑sourced the HOST framework (Human‑to‑robot One‑Shot Skill Acquisition). The framework enables robots to acquire new skills by watching just a few dozen seconds of human video, while retaining previously mastered skills.

3. China's weekly large‑model call volume surpasses that of the US for the fourteenth consecutive week

As of August 4, according to the latest data from OpenRouter, global AI large‑model total call volume for the week of July 27 to August 2 reached 56.8 trillion tokens, down 2.07% week‑on‑week. Among the listed AI large models, Chinese models recorded a weekly call volume of 28.13 trillion tokens, down 14.76% week‑on‑week, while U.S. models recorded 4.38 trillion tokens, up 87.18% week‑on‑week. China's weekly large‑model call volume has now surpassed that of the United States for fourteen consecutive weeks, maintaining its global lead.
