Dear Readers:
    This is the supplementary material for our paper titled "HiFlow: Training-free High-Resolution Image Generation with Flow-Aligned Guidance".
    We have included a slightly compressed version of the additional qualitative results due to the file size limitations for supplementary materials. We apologize for the inconvenience, but we have ensured that the content is still clear and informative. 
    Additionally, we have provided the uncompressed version of the teaser figure in the paper for your reference. Moreover, we have included the source code for HiFlow. 
    We kindly invite you to also consult our appendix, which contains complementary information (e.g., more discussions, the psedo code, etc) that supplements the main paper.
    We hope this will provide further insights into our work. Thank you very much! 
Sincerely,
Authors
