    ### About Dynamic Highscores
    
    This platform allows users to select benchmarks from HuggingFace datasets and evaluate models against them.
    Each user can submit one benchmark per day (admin users are exempt from this limit).
    All evaluations run on CPU only to ensure fair comparisons.
