Statistical attribute alignment for black-box generative AI via output post-processing

Kevin Jiang, Morgane Austern, Edgar Dobriban et al.1 min readarXivSep 25, 2026

Key Takeaway for Students

Generative AI systems are increasingly used, but aligning their outputs with user requirements poses a continuing challenge. Here, we aim to ensure that the distribution of an attribute of an AI-generated output aligns with a user-specified target. This is motivated by examples such as fairness, where we want to ensure that a protected attribute (e.g., gender, race, or age cate

This paper addresses a critical challenge in generative AI: ensuring model outputs align with specific statistical distributions, particularly for fairness and synthetic data generation. For ML engineers, this means developing methods to control generative models even in black-box settings, which is crucial for deploying responsible and useful AI systems.

Interview questions

Describe how you would approach aligning the gender distribution of generated faces from a black-box GAN to a target demographic, given only query access.
What are the trade-offs between exact and approximate attribute alignment in a black-box setting, especially concerning computational cost and output quality?
Design a system architecture for a service that takes a black-box generative AI model and a user-specified attribute distribution, and returns a set of outputs that statistically align with the target distribution, considering scalability and latency.
