  • Auto-dispatch: numpy arrays use FAISS, cupy arrays use cuML - data stays on GPU
  • Batched operations: vectorized neighbor search & imputation (no Python row loops)
  • Backwards compatible: FaissImputer alias with deprecation warning → use FastKNNImputer
  • New dependency: array-api-compat for array-agnostic operations
