Launched by Microsoft Research, MatterGen is a generative AI tool for material design. It can directly generate new materials with specific chemical, mechanical, electronic, or magnetic properties based on application design requirements, providing a new paradigm for material exploration. This tool is expected to accelerate the R&D process for novel materials, lower R&D costs, and play a significant role in fields such as batteries, solar cells, and CO2 adsorbents. Currently, MatterGen's source code is open-sourced on GitHub for public use and further development.
