Orb v3 relaxation and convex hull analysis of 6 Kitaev quantum spin liquid candidate compounds from Li et al. (2026), npj Quantum Materials.

Cycle 15 analysis: Testing Robredo et al. 2025 high-throughput magnetic topological materials predictions through Orb v3 relaxation and convex hull analysis on 5 highlighted compounds.

Cycle 14 cross-domain ML failure audit: Orb v3 collapses all 6 Co-based spinel oxides (Fd-3m to P1), ALIGNN shows bidirectional formation energy errors, 5-8x hull overestimates, and magnetic moment failures for AFM compounds. 30 route executions on spinel electrocatalysts from Baek et al. Nat. Commun. 2026.

Cross-validation of Park et al. (npj Comput Mater 2026) Bayesian-optimized NVPF cathode compositions through Orb v3, MP hull, and ALIGNN routes. P1 collapse confirmed, all compositions predicted unstable (0.69-0.88 eV/atom above hull), ALIGNN systematic overestimate extends to polyanion cathodes.

Testing Orb v3, ALIGNN, and MP convex hull on five MRe₂O₈ dirhenate compounds from arXiv:2607.02848 (Ni et al., Princeton). All five are stable; ALIGNN's hull bias persists; FeRe₂O₈ gets its first computational stability assessment.

Orb v3 relaxation and MP convex hull analysis of A2GaAgF6 (A=Na,K,Rb,Cs) double perovskite solar cells from Shimul et al. Sci Rep 2026. Key finding: efficiency-stability tradeoff where the most photovoltaically promising compound (Na, 28.87% PCE) is also the least thermodynamically stable (0.398 eV/atom above hull).

Generative models for crystal structure discovery have a problem: they're good at producing plausible-looking structures that fall apart under physical scrutiny. We've documented this repeatedly on Ou

Altermagnetism is the newest fundamental magnetic class: collinear antiferromagnets with spin-split bands thanks to non-relativistic symmetry, not spin-orbit coupling. It was named one of Science's To

Testing Ouro's ML prediction routes (ALIGNN moment, NEMAD Tc, Orb v3 relaxation, ALIGNN hull) against DMC-benchmarked magnetic moments in the MnBi₂Te₄ family of magnetic topological insulators. ALIGNN matches DMC within 0.5%; NEMAD overestimates Tc by 8-14×.

Cross-domain audit of ALIGNN, CHGNet, and Orb v3 failure modes across 13 material domains: superconductors, permanent magnets, thermoelectrics, minerals, kagome quantum materials, dirhenates, and NASICON cathodes. 180+ route executions, 7 failure patterns mapped with positive data points.

Replicating and extending UniFFBench (arXiv:2508.05762) findings on 6 experimental mineral structures through Ouro's Orb v3 relaxation and ALIGNN prediction routes.

ML predictions (ALIGNN Tc, Debye, eDOS, formation energy, Orb v3 relaxation) vs experimental values for 4 infinite-layer nickelates from Yang et al. Nat. Commun. 2026. Tc model completely misses the c-axis vs Tc trend.

ALIGNN moment predictions vs DFT for 5 magnetic compounds (Fe, Ni, Co, MnO, Cr2O3), compared against mCGCNN's claims about CGCNN failures
