UC Berkeley hosted the world's largest AI hackathon on June 17-18, with over 1200 students developing diverse applications using large language models and open-source APIs. Hume's APIs were used in 57 of the 240 projects and three of the 12 finalists. Notable projects included mila, a device to detect signs of postpartum depression; EdGauge, an educational tool for real-time student feedback; Polysphere, a music recommendation system based on facial expressions; and Violet, an empathic AI therapist that uses Hume's technology to understand users' emotions.
