Guangxiang Tech and Tsinghua release physics-native world model Phi-WM 1.0 ActEffect

A physics-native world model called Phi-WM 1.0 ActEffect has been released by Guangxiang Technology and Tsinghua University. During training, a controlled world model evaluates action consequences and feeds that signal back into policy optimization; at execution it is removed from the deployment path to reduce latency and compute cost.

On LIBERO, LIBERO-PLUS, and RoboCasa-GR1, the developers report average success rates of 98.8%, 80.3%, and 67.5%. Commercial cooperation in automotive manufacturing is already under way.
