    The following freqaimodel is released to sponsors of the non-profit FreqAI open-source project.
    If you find the FreqAI project useful, please consider supporting it by becoming a sponsor.
    We use sponsor money to help stimulate new features and to pay for running these public
    experiments, with a an objective of helping the community make smarter choices in their
    ML journey.

    This strategy is experimental (as with all strategies released to sponsors). Do *not* expect
    returns. The goal is to demonstrate gratitude to people who support the project and to
    help them find a good starting point for their own creativity.
