Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

Snorkel Flow Platform

Data-development platform where teams write programmatic labeling functions and use AI-assisted labeling to build and refine training data for machine learning and LLM systems, instead of hand-labeling manually.
Snorkel Custom Data Development Data service

Bespoke dataset, environment and benchmark development for organizations with specialized failure modes existing datasets don't cover.
Snorkel Data Series Data service

Off-the-shelf curriculum-structured training/eval datasets for frontier-model task areas (terminal coding, software engineering, enterprise workflows, computer use, scientific research), with rubrics and difficulty tiers built in.
Snorkel Specialized Agents Agent platform

Develops specialized AI agents for enterprise tasks, built on Snorkel's data-development stack.
