Social AI platform building real-time video and character generation models

Software Development San Francisco, California 201–500 employees Founded 2023 Privately Held

Cantina Labs builds real-time generative models that animate AI characters for social storytelling, paired with native iOS (Swift, UIKit) and Kotlin/Jetpack Compose mobile apps. The stack of PyTorch, Ray, Spark, Airflow and FFmpeg across AWS, GCS and Azure points to heavy in-house video model training, and recurring pain points center on video data pipeline scale, storage spend and inference cost. Hiring skews senior and research-heavy.
