    Behold! The winners of the @southpkcommons x @OpenAI Hackathon! Over 40 teams spent 45 hours last weekend hacking together these and many more impressive projects. Thanks again to our judges @snsf, Irina Kofman, @mvernal, @arnaudai, & @finn_meeks! 🧵

    4 top-tier startup accelerator programs opened applications in the last week (spoiler, I work for one). YC is doing advanced interviews for AI companies. Programs are competing for founders like it's 2021 again. Here's a list of accelerators accepting applications:
