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.

Pseudocode Yes Algorithm 1 Training Blockwise Flow Matching (BFM) Algorithm 2 Training Feature Residual Network (FRN) Algorithm 3 Inference Algorithm 4 Efficient inference with Feature Residual Network
Open Source Code Yes Code is available at https://github.com/mlvlab/BFM.
Open Datasets Yes Extensive experiments on Image Net 256 256 demonstrate that BFM establishes a substantially improved Pareto frontier over existing Flow Matching methods
Dataset Splits Yes Most of the experiments are conducted on the Image Net dataset at a resolution of 256 256, unless stated otherwise. We follow the experimental setup established by Si T [22] and REPA [26].
Hardware Specification Yes All experiments are conducted with a global batch size of 864 using eight NVIDIA A100 GPUs.
Software Dependencies No We implement our model based on the original Si T implementation [22] with recent improvements such as Swi GLU [68] activations, RMS normalization [68], and Rotary Positional Embeddings (Ro PE) [69]. Following Fi Tv2 [6], we reassign model parameters and adopt Ada LNLo RA [70] within transformer blocks to mitigate the parameter overhead of Ada LN modules.
