1.3.1.I Other training data size: 607,684 crystal structures
1.3.1.J Other training data content: DFT-relaxed inorganic crystal structures (unit cell lattices, atomic fractional coordinates, and element types) from Materials Project (v2022.10.28) and Alexandria; filtered to energy above hull < 0.1 eV/atom, excluding noble gases and elements with Z>84 or Tc, Pm.
1.3.2 Latest date of data acquisition/collection for model training: 18-Aug-2023
1.3.3 Is data collection ongoing to update the model with new data collection after deployment? No
1.3.4 Date the training dataset was first used to train the model: 18-Aug-2023
1.3.5 Rationale or purpose of data selection: Datasets of DFT-relaxed inorganic crystalline materials were selected to train a diffusion model that jointly generates atomic coordinates, element types, and unit cell lattices for stable materials across the periodic table. Filtering to structures within 0.1 eV/atom above reference convex hull emphasizes stability, while excluding certain elements and limiting to ≤20 atoms targets the intended model scope and computational feasibility
