Spawning AI offers Source.Plus, a marketplace that uses classifier models to detect nudity, gore, and personally identifiable information in images, helping AI developers curate consenting, high-quality training datasets.

Source.Plus is seeded with nearly 40 million public domain and Creative Commons Zero (CC0) images sourced from libraries and museums worldwide. To help developers filter the dataset, Spawning trained classifier models designed to detect nudity, gore, and personally identifiable information within the image collection. The platform also filters out images whose creators have opted out via the Do Not Train Registry. Users can adjust the detection thresholds of these classifiers to flexibly filter the dataset to their needs. Source.Plus launched in limited beta in 2024, with plans to expand to licensed content from rights holders.
