Snorkel AI

Snorkel AI is a data-development / AI data platform built on the open-source Snorkel weak-supervision library. The enterprise Snorkel Flow platform supports programmatic labeling, data curation, model training, and evaluation, and is driven programmatically through a Python SDK that targets a per-instance REST API rather than a single public hosted endpoint. Snorkel also delivers Expert Data-as-a-Service for frontier-model training and evaluation data.

Snorkel AI publishes 3 APIs on the APIs.io network: Snorkel Flow SDK / Platform, Programmatic Labeling, and Evaluation. Tagged areas include AI, Data Development, Programmatic Labeling, Weak Supervision, and Evaluation.

Snorkel AI’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.
