Enhanced Materials Discovery Workflow
Our novel multi-stage workflow combines state-of-the-art generative models, universal machine learning interatomic potentials (uMLIPs), and specialized graph neural networks. This synergistic approach drastically reduces computational cost and improves the accuracy of identifying compounds close to the convex hull, achieving a 99% success rate within 100 meV/atom—a threefold improvement over prior methods. The process begins with MATRA-GENOA for candidate generation, followed by ORB-V2 for initial geometry relaxation, ALIGNN for rapid distance-to-hull prediction, and culminates in DFT validation for high-accuracy results.

Alexandria Database Expansion & Quality Assurance
The ALEXANDRIA database has undergone a massive expansion, now housing 5.8 million DFT-calculated structures, with 175,000 confirmed to be on the convex hull. This includes 1.3 million newly DFT-validated compounds and 74,000 previously undiscovered stable materials. A critical finding is Alexandria's predicted structural disorder rates (37-43%), which closely align with experimental databases like ICSD (35%) and are significantly lower than other recent AI-generated datasets such as GNOME (80-84%). This indicates a strong bias towards ordered crystal structures, enhancing the reliability and synthesizability of discovered materials.

Key Discoveries & Advanced Material Properties
Beyond raw numbers, the expanded Alexandria database facilitates deep insights into fundamental materials science. Analysis of space group distributions reveals specific preferences and identifies underrepresented groups, while coordination number analysis confirm chemical trends and uncovers novel, unconventional bonding environments. The database also enables the study of emergent 'collective' properties, such as the nobility index, which quantifies a material's connectivity within the convex hull. This metric helps identify central 'hub' materials important for synthesis and processing, and analysis suggests a sub-linear scaling of network connectivity, indicating potential saturation in local phase relationships.
Insights from Convex Hull Connectivity
Investigation into the convex hull reveals fundamental patterns in space group distributions, coordination environments, and phase stability networks. A significant finding is the sub-linear scaling of convex hull connectivity, where the average number of neighbors within the stability network grows at a slower rate than the total number of materials. This suggests a form of saturation in local connectivity, offering insights into which materials play central roles in synthesis pathways as decomposition products or stable intermediate phases. Elemental distributions and coordination number analysis confirm well-established chemical trends while also highlighting structurally unconventional materials, such as six-fold coordinated carbon and nitrogen, indicative of antiperovskite compounds.

Technical Methods & AI Models
The core of our methodology relies on Density Functional Theory (DFT) calculations performed using VASP, ensuring compatibility with the Materials Project database. Geometry optimizations and total energy calculations employ PBE exchange-correlation functional with U corrections for specific elements, with convergence criteria set at 0.005 eV/Å for forces.
For machine learning models, ORB-V2 is employed as the universal machine learning interatomic potential for preliminary geometry relaxation due to its balance of accuracy and computational cost. ALIGNN, a graph neural network, is trained to predict the distance to the convex hull, acting as a highly efficient filter after uMLIP relaxation.
For fine-tuning force fields, the GRACE model, built upon the Atomic Cluster Expansion (ACE) framework, is used, demonstrating state-of-the-art performance on benchmarks like WBM when trained on the extended sAlex25 dataset.
