P-Guide cuts CFG inference time by 50% with single-pass steering

Researchers have introduced P-Guide, a novel framework designed to enhance the efficiency of conditional generation in flow matching. This method significantly reduces computational overhead by performing guidance in a single inference pass, unlike traditional approaches that require dual forward passes. P-Guide achieves this by modulating only the initial latent state, effectively steering generation from the prior space and maintaining competitive fidelity and prompt alignment while reducing inference latency by approximately 50%.

    P-Guide: Parameter-Efficient Prior Steering for Single-Pass CFG Inference

    arXiv:2605.06124v1 Announce Type: new Abstract: Classifier-Free Guidance (CFG) is essential for high-fidelity conditional generation in flow matching, yet it imposes significant computational overhead by requiring dual forward passes at each sampling step. In this work, we addres…
