- Design modular, composable model interfaces β e.g., DAG-style composition, DRY config, not requiring unused dependencies, separable training and inference code
- Support complex training schemes β e.g., curriculum learning or learned feature extractors
- Ensure that we always know how each model was trained and on what data
- Implement best practices for distributed training β e.g., Megatron, DeepSpeed
