A new research paper proposes that the selection of data during supervised fine-tuning (SFT) acts as an implicit alignment mechanism, rather than alignment being solely a later step. The study compares various online data selection methods—random, loss-based, quality-based, and diversity-based—demonstrating that these choices significantly alter model behavior, such as refusal rates and verbosity, even without explicit preference optimization. The researchers introduce Alignment Drift Auditing (ADA) to quantify these selection-induced behavioral shifts and Alignment-Aware Selection (AAS) as a diagnostic tool to manage drift while maintaining data efficiency.

IMPACT Suggests that data selection during fine-tuning is a critical, often overlooked, factor in AI alignment, potentially simplifying future alignment strategies.
