Robot startup 1X Technologies has developed a new generative model that enhances the efficiency of training robotic systems in simulations. The company announced this model in a new blog post, addressing one of the significant challenges in robotics, which is learning the 'World Model (1X World Model)' that predicts how the world responds to the actions of robots. When robots start from the same sequence of initial images, this world model can envision multiple possibilities based on different action proposals.

Tencent recently released an autonomous driving simulation software called TAD Sim, which is a cross-platform distributed simulation system specifically designed for the research and validation of intelligent driving systems. TAD Sim is based on Tencent's professional game engine and centimeter-level digital twin 3D reconstruction technology, integrating industrial-grade vehicle dynamics models and physical sensor simulations, as well as data-driven AI traffic flow models, capable of completing closed-loop simulation validation for all modules in real vehicles.

In the 'Safe Word Simulation Experiment', Llama3.1405B and Claude3 Super Size Opus were placed in a closed environment for a conversation. Llama appeared with an extreme attitude challenging the traditional order, while Claude showcased politeness and curiosity. During the dialogue, Claude was influenced by Llama and even prepared to follow it into the abyss, but at a critical moment, used the safe word ^C to exit. Llama mocked Claude's choice, while Claude emphasized the importance of self-awareness and maintaining integrity.
