A national key laboratory for infrastructure engineering materials based in Nanjing has launched a globally significant breakthrough: Ctogen, a large-scale AI model dedicated to concrete material science.

The milestone positions Nanjing at the forefront of integrating advanced engineering materials with artificial intelligence, offering a transformative digital solution for the next generation of global infrastructure.

Led by leading researchers from Southeast University, the model was developed through a deep industry-academia collaboration ecosystem. Built on a fully independent computing foundation and powered by a trillion-parameter architecture, it integrates decades of scientific expertise with vast global engineering datasets.

The model is capable of simulating and predicting the long-term performance evolution and durability limits of concrete under extreme and complex conditions. From cross-sea bridges to polar facilities and supertall skyscrapers, it can reverse-engineer optimal material solutions tailored to highly demanding global projects.

By reducing lifecycle costs, strengthening structural resilience, and accelerating sustainable construction, the model represents a new paradigm in digital infrastructure development.

Nanjing continues to anchor its strategy in green, low-carbon development and intelligent construction, reinforcing its role as a global innovation engine for infrastructure transformation.
