Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

| Research Type | Experimental | We then verify these insights in real-world, nonlinear diffusion models: over a broad range of noise levels, linear CFG resembles the behavior of its nonlinear counterpart. Although the two eventually diverge at low noise levels, we discuss how the insights from the linear analysis still shed light on the CFG s mechanism in the nonlinear regime. |

| Pseudocode | No | The paper includes mathematical equations, derivations, and descriptions of methods, but it does not contain any explicitly labeled 'Pseudocode' or 'Algorithm' blocks, nor does it present structured steps in a code-like format. |
| Open Source Code | No | The code and instructions for reproducing our experiments will be released at: https://github. com/Morefre/Towards-Understanding-the-Mechanisms-of-Classifier-Free-Guidance. git. |
| Open Datasets | Yes | We perform our experiments on CIFAR-10 [42] and Image Net dataset [29] |
| Dataset Splits | No | The paper does not explicitly provide training/test/validation dataset splits with percentages, counts, or predefined citations. It mentions using the CIFAR-10 and ImageNet datasets and generating samples from a trained diffusion model, but it does not detail how these datasets were originally split for training or evaluation. |
| Hardware Specification | Yes | All experiments are performed on A100 GPUs with 80 GB memory. |
| Software Dependencies | No | The paper mentions using specific models like EDM-1 and EDM-2, but does not specify version numbers for programming languages (e.g., Python) or libraries (e.g., PyTorch, TensorFlow, CUDA). |
| Experiment Setup | Yes | CFG is applied to the entire noise interval σ(t) [0.002, 80], with guidance strength γ = 4. The samples are generated using 20 steps of Euler method (first-order sampler). |
