Internal Guidance for Diffusion Transformers

Published:Dec 30, 2025 12:16
1 min read
ArXiv

Analysis

This paper introduces a novel guidance strategy, Internal Guidance (IG), for diffusion models to improve image generation quality. It addresses the limitations of existing guidance methods like Classifier-Free Guidance (CFG) and methods relying on degraded versions of the model. The proposed IG method uses auxiliary supervision during training and extrapolates intermediate layer outputs during sampling. The results show significant improvements in both training efficiency and generation quality, achieving state-of-the-art FID scores on ImageNet 256x256, especially when combined with CFG. The simplicity and effectiveness of IG make it a valuable contribution to the field.

“LightningDiT-XL/1+IG achieves FID=1.34 which achieves a large margin between all of these methods. Combined with CFG, LightningDiT-XL/1+IG achieves the current state-of-the-art FID of 1.19.”

Guided Path Sampling Improves Diffusion Model Refinement

Published:Dec 28, 2025 11:12

ArXiv

Analysis

This paper addresses a key limitation in iterative refinement methods for diffusion models, specifically the instability caused by Classifier-Free Guidance (CFG). The authors identify that CFG's extrapolation pushes the sampling path off the data manifold, leading to error divergence. They propose Guided Path Sampling (GPS) as a solution, which uses manifold-constrained interpolation to maintain path stability. This is a significant contribution because it provides a more robust and effective approach to improving the quality and control of diffusion models, particularly in complex scenarios.
Reference

“GPS replaces unstable extrapolation with a principled, manifold-constrained interpolation, ensuring the sampling path remains on the data manifold.”

Composite Classifier-Free Guidance for Multi-Modal Conditioning in Wind Dynamics Super-Resolution

ArXiv

Analysis

This article describes a research paper on a specific application of AI in wind dynamics. The core focus is on improving the resolution of wind dynamics simulations using a technique called "Composite Classifier-Free Guidance" with multi-modal conditioning. The paper likely explores how different data sources (multi-modal) can be combined to enhance the accuracy and detail of wind simulations, which could have implications for weather forecasting, renewable energy, and other related fields. The use of "Classifier-Free Guidance" suggests an approach that avoids the need for explicit classification, potentially leading to more efficient or robust models.
