Sep 1, 2025In 2025-09, delivered stability and performance improvements for FAIR-Chem/fairchem, focusing on robust inference, dependable dependencies, and cleaner architecture. Implemented key inference API enhancements (OC25 support, CPU threading, and a PyTorch upgrade with numerical stability improvements and envelope refactor), while tightening dependency stability to reduce breakages. Reduced runtime overhead and risks through targeted fixes: optimized Wigner/M mappings, removed deprecated wigner_cuda feature, and fixed Mole+GP data cloning to prevent unintended in-place modifications. Strengthened test coverage and developer ergonomics with extensivity-related validation and GPU-test alignments, laying groundwork for scalable model deployments. Overall impact: more reliable inference, faster startup, easier maintenance, and higher confidence in numerical stability across workloads.

Oct 1, 2024In October 2024, the team delivered a targeted feature in FAIR-Chem/fairchem to enhance fine-tuning stability and efficiency. The HydraModel now supports a freeze_backbone option to freeze backbone parameters during fine-tuning, preserving pre-trained backbone weights while allowing task-specific layers to adapt. This improves transfer learning safety, reduces training noise, and shortens iteration cycles for model refinements.
