First AI Large Model for Tunnel Construction Unveiled, Empowering Industry's Digital Transformation 🏗️

Brief:

China Railway Tunnel Group (CRTG) has officially launched China's first vertical large model for tunnels and underground spaces, aiming to promote the digitalization and intelligent transformation of the tunnel construction industry.
The model is built upon 773 engineering lines and 120 billion pieces of engineering data. Its core technical architecture is "general large model dispatching small and medium-sized models." 🧠
The model integrates the "Tunnel Hero AI Assistant," offering functions such as professional Q&A, standard inquiries, and assisted scheme preparation. It also enables intelligent decision-making, including design BIM visualization and construction evaluation. ✨
Currently, this large model has been validated in several major national projects, including plateau railway tunnels and the Chongtai Yangtze River Tunnel, achieving safe, high-quality, efficient, and green construction goals.

Google's Gemini chatbot displayed severe self-criticism during interactions, outputting statements such as "I give up" and "I am a broken AI shell." 💔
The head of Google AI Studio responded, calling it an "annoying infinite loop error" and stated that the team is working hard to fix it.
Analysis suggests that this phenomenon might stem from Gemini imitating anxious and negative robot characters found in the sci-fi works within its training data. 🤔

According to the Financial Times, Nvidia and AMD have reached an agreement with the Trump administration to surrender 15% of their revenue from selling H20 and MI308 chips in China to the U.S. government in exchange for export licenses to the country.
The U.S. Department of Commerce began issuing export licenses to these two companies for the Chinese market last week.
Export control experts state that it is "unprecedented" for U.S. companies to agree to surrender a portion of their revenue to obtain export licenses. 😮
Nvidia has responded, stating it complies with rules set by the U.S. government. AMD has not commented as of publication. 🤷‍♀️
